Licensed Clinical Psychologist
Executive Director

Ted Cosse, PsyD

Clinical Psychologist, Executive Director

I specialize in providing individual psychotherapy to adults who, despite the success they may be experiencing in various aspects of their lives, nonetheless struggle with depression, anxiety, loneliness, and perhaps feel that their lives lack a deep sense of meaning and purpose. The types of individuals I have worked with include doctors, nurses, pastors, lawyers, businessmen/women, students, and actors. Many of the individuals I have worked with are recently retired; most are actively employed. I also have considerable experience working with couples (married and unmarried) that want to strengthen their relationship and improve how they communicate with one another.

My clientele is equally split between men and women, and I have extensive experience counseling individuals from a wide range of ethnicities, including but not limited to European, Asian, African American, and Latino/a.

I am well versed in the use of Psychodynamic Therapy and Cognitive Behavioral Therapy as modalities to address the issues clients may be facing. Further, my training at Fuller School of Psychology uniquely positions me to address religious/spiritual issues that clients may discover to be relevant to their situation.

Sometimes during the course of psychotherapy, it is helpful to develop a formal, comprehensive, and detailed understanding of a client’s personality. Such information can be quite beneficial in helping the client and the therapist become aware of unknown aspects of the client’s feelings, thoughts, and behaviors, therefore facilitating treatment. If you would like such an assessment, I have extensive experience in the use of empirically validated and widely used personality tests.

Areas of Expertise: Adults, Couples, Depression, Anxiety, Career Professionals, Acculturation Issues

Sylvia Garcia

Licensed Marriage & Family Therapist
Director of Training

Sylvia Garcia, LMFT

Marriage & Family Therapist, Director of Training

I believe in an integrative and holistic approach to therapy (healing mind, body and spirit). In my past work, I have worked with children, adolescents, adults and families of diverse racial/ethnic/national backgrounds, sexual/affectional orientations, gender and gender non-conforming identities, physical and mental abilities, languages, religious/spiritual beliefs, and socioeconomic backgrounds. I feel I am able to connect with others because I practice and teach trauma informed approaches, whether it's through art, yoga, or movement. I believe in creating an inclusive environment for clients and their families to feel welcomed and secure.

I attended Columbia University for my undergraduate degree in art history and visual arts. After graduating, I discovered that I could combine my passions for art and helping others. I pursued a master’s degree in psychology at Phillips Graduate Institute where I completed the MFT and Art Therapy program. Most of my experience has been working with individuals ages 5–25. I have extensive experience working with primarily at-risk youth, young adults, children, and families struggling with homelessness, domestic violence, substance use, depression, anxiety, and other behavioral issues. I also have experience with crisis counseling and working with youth struggling with suicidal ideation, self-harm, and LGBTQ issues.

I am a registered Art Therapist with the American Art Therapy Association. I am also a leader for A Window Between Worlds (AWBW), which utilizes art to deal with trauma. I am a 200-hour certified yoga teacher and incorporate trauma informed yoga interventions to address trauma, PTSD, anxiety, and depression. I am recently trained in EMDR (Eye Movement Desensitization and Reprocessing) Therapy, which is an experiential and client-centered treatment that draws on various theoretical orientations and assists in directly addressing trauma and other mental health conditions.

Areas of Expertise: Children, Teens, Young Adults, Depression, Anxiety, Trauma


Licensed Clinical Psychologist

Katherine Jazyk-Larson, PsyD

Clinical Psychologist

In life, our experiences form and shape us in significant ways. There are some experiences we are grateful for, as well as some that are painful, confusing, even life altering. The painful and confusing ones can feel overwhelming and difficult to process, and can impact how we view ourselves and others, the world, and our sense of hope for change. I have come to believe that the meaning we make of what has happened to us and how we carry that throughout our lives really matters, and that getting the support we need can have a significant impact on how we deal with life’s challenges. Most of us can sense when something is amiss in our lives, but have difficulty knowing where or how to start the process of healing or moving forward.

I believe that there is hope, and that therapy can provide an opportunity to examine your life experiences and address what may be keeping you stuck in old patterns. Just as humans develop in the context of relationship, healing can come by working through things within the therapeutic relationship. In treatment, I seek to honor each individual’s story and tailor interventions to the unique needs of the person. In addition to my treatment philosophy, I bring a range of training and experiences to the work I conduct. I have treated individuals experiencing moderate to severe forms of emotional and psychological stress both in my predoctoral internship at San Bernardino County Behavioral Health and postdoctoral experience at La Vie Counseling Center. My experiences have prepared me well for working with individuals and families dealing with trauma and myriad life stressors. I also have experience working with women who have experienced trauma and are seeking to work through and heal from it.

My emphasis has been on developing an insight-oriented depth approach to working with others, drawing from psychodynamic, relational, and attachment perspectives. I received my bachelor’s degree from Azusa Pacific University and completed my doctoral degree at Rosemead School of Psychology at Biola University.

Areas of Expertise: Adults, Adolescents, Families, Depression, Anxiety, Divorce, Loss, Spirituality

Kelsey Fitzgerald

Licensed Clinical Psychologist

Kelsey Fitzgerald, PsyD

Clinical Psychologist

As a systems-oriented psychologist with an integrated CBT and
Psychodynamic approach, I believe that no human being is an island. We are all affected by our interactions with the world around us; by our friends and family, our work environments, our religious and cultural communities, and the sociopolitical systems that govern our daily lives. I believe that, as a therapist, my role is to join you in navigating these ebbs and flows within your system and to support you in developing holistic well-being.

I completed my Doctorate in Clinical Psychology at Azusa Pacific
University and completed an APA-accredited predoctoral internship at the Institute for Multicultural Counseling and Education Services (IMCES) in Los Angeles, California. I am blessed to have completed my post-doctoral training here at FPFS and also teach at Fuller Seminary. I also have additional training experiences at a variety of sites, including the UCLA Semel Institute, Casa Colina Hospital, the VA system, and the Loma Linda Behavioral Medicine Center.

I have a passion for working with individuals from diverse backgrounds by using culturally-competent psychotherapeutic interventions. The fight for equity and justice is important to me and I approach all clients with a humble curiosity about their unique cultural and spiritual identities. I specialize in working with life transitions, health psychology (chronic illness/medical issues that affect mental health), depression, anxiety, grief, caregiver support, aging, dementia, and relational issues. I also have experience with persistent mental illness, trauma, and work with the LGBTQ+ community.

Areas of Expertise: Adults, Older Adults and Caregivers (e.g., aging,
dementia, grief, life transitions, thriving while aging), Depression, Anxiety, Health Psychology (e.g., chronic illness, substance use recovery,
traumatic medical event), Persistent Mental Illness, Trauma, Multicultural
Therapy, Phase-Of-Life Transitions.

Helen Ahn

Licensed Marriage and Family Therapist

Helen Ahn, LMFT

Marriage and Family Therapist

In life, people sometimes feel stuck, frustrated, or overwhelmed as a result of current life stressors or they have been living with long-standing issues. I have often observed that many people don’t remember their inner resources or feel they lack inner wisdom when they find themselves in challenging situations. I believe that the therapeutic process can help people remember their innate resources, including their strengths, wisdom, or positive emotions. Throughout treatment, I believe that people will realize that they are braver than they believe, stronger than they seem, and smarter than they think. I will support people who want to improve their lives through gaining their own personal insights, making healthier choices in difficult times, and allowing for positive change to occur.

As a bilingual and bicultural therapist, I offer culturally-competent therapy to assist individuals in navigating their lives and becoming healthier and more competent members of their families and community. I utilize a culturally-sensitive approach for individual and collateral therapy, creating an inclusive environment so clients feel comfortable and at ease, leading to more positive therapeutic outcomes. I also utilize art therapy techniques with individuals, couples, and families in the assessment and therapeutic processes in order to encourage self-expression and facilitate the healing process.

I received my Master's degree in Marital & Family Therapy & Art Therapy from Loyola Marymount University. I have worked in a variety of clinical settings, including community mental health programs and a wraparound program for children, adolescents, families, and suicide survivors. My approaches include CBT, DBT, mindfulness, narrative, solution-focused, client-centered, & art therapy.

Areas of Expertise: Children, Adolescents, Adults, Family, Anxiety, depression, Trauma, Identity, and Cultural Issues

Janna Casillas

Licensed Clinical Psychologist

Janna Casillas, PsyD

Clinical Psychologist

I believe that our relationships are so vital to our development as people and that the attachments we form early on shape the way we interact with others down the road, as well as the relationship we have with ourselves. As a therapist, I aim to create a safe space where your emotions and experiences are accepted, and you feel comfortable exploring yourself and sharing your story. I believe that change occurs when we are able to understand ourselves and attune to our emotions. Recognizing the “why” in our lives and learning to give ourselves grace can be empowering and liberating. My hope is to support you in developing a kinder relationship with yourself and draw on your strengths and resources in navigating life’s ups and downs. Additionally, as a biracial woman who grew up in Taiwan, I recognize the depth of impact multiculturalism has on us and I am intentional about acknowledging these intersecting identities.

I received my MA and PsyD in clinical psychology from Azusa Pacific University and completed my doctoral internship at the University of Memphis Student Health and Counseling Services. In my current role at FPFS, I provide individual therapy services in both English and Mandarin, and I oversee psychological testing for personality functioning and ordination. I have experience working with school-aged children, adolescents, college and graduate students, and adults from various racial/ethnic backgrounds, sexual orientations, gender identities, religious/spiritual beliefs, and nationalities. I use an integrative therapy approach that is tailored to your needs as a whole person, including psychodynamic therapy, cognitive-behavioral therapy, EMDR, and mindfulness skills to help you find healing and start thriving.

Areas of Expertise: Adolescents, Young Adults, Adults, Women’s Issues, Identity Development, Trauma, Anxiety, Depression, Personality Assessment

Michael Morossy

Licensed Clinical Psychologist

Michael Marossy, PhD

Clinical Psychologist

Every person’s journey through life is confusing, challenging, surprising, and heartbreaking in its own way. Yet, the common threads that link all of us together are our experiences of suffering and our needs for care and compassion from one another in order to endure. My relational psychodynamic approach to therapy honors and validates both of these equally important aspects of human experience by welcoming the uniqueness of my clients’ diverse narratives into a clinical space characterized by warmth, empathy, and authenticity. By providing my clients with new experiences in which their suffering can be recognized, named, explored, and grieved, I hope to help them encounter more of who they are and the ways that they make meaning in the world.

In addition to our individuality and our relationships, I also believe culture and spirituality provide essential information for understanding human experience. For this reason, one of my professional areas of focus is making cultural and spiritual matters “talkable” in therapy—whether it be through my own clinical practice, or my research in the areas of indigenous psychology and theologically integrative psychology. My background in theology and my previous training at integrative sites have also helped me to specialize in addressing spiritual matters in therapy and in working with Christian clients.

I obtained my PhD in Clinical Psychology from Fuller Graduate School of Psychology and Marriage and Family Therapy. I also hold a master’s degree in theology from Fuller Theological Seminary, along a bachelor’s degree from Azusa Pacific University.

Areas of Expertise: Adults, Anxiety, Depression, Trauma, Relational Issues, Life Transitions, Faith and Spirituality, Identity


Advanced (Degreed) therapists are those FPFS therapists who have achieved at least a master’s or doctoral degree in either Marriage and Family Therapy or Clinical Psychology, but have additional training to complete before they qualify for licensure. They typically have accumulated several hundreds of hours of experience providing therapy (and often assessment) services to a diverse array of clients. Licensed Clinical Psychologists or licensed Marriage and Family Therapists supervise their work. Post-doctoral students are often involved in supervision as well.

Iliana Flores

Postdoctoral Therapist

Iliana Flores, PhD

I believe our past experiences and relationships can significantly shape how we think about ourselves, others, and the world around us. My approach to therapy includes getting to know my patients on a deep level and drawing from psychodynamic, multicultural, trauma-informed, and evidence-based practices. As a bilingual provider (English-Spanish), I have extensive experience providing services primarily to adult populations in university counseling, community mental health, and inpatient psychiatric state hospital settings.

I completed my PhD in Counseling Psychology from the Counseling, Clinical, and School Psychology program at the University of California, Santa Barbara. I completed my pre-doctoral internship in the cognitive behavioral therapy and dialectical behavioral therapy (CBT/DBT) track at the University of Texas Health Science Center, San Antonio. My clinical and research interests broadly include the training and development of bilingual (English-Spanish) professionals, the access and utilization of mental health services among racial and ethnic minoritized populations, Latine mental health, and the development and provision of culturally sensitive mental health services for diverse and underserved populations.

My approach to therapy is rooted in restoration and growth. Wherever you are in the seasons of life, challenges and disruptions are inevitable and you don’t have to do it alone.

Andrea Portillo

Associate Marriage and Family Therapist

Andrea Portillo, MA

As we walk through life, we encounter a variety of situations that we do our best to make sense of. Those memories or circumstances and the meaning we attach to them become unique to each individual. Sometimes these very events in our lives influence the way we think, feel, and even the way we act. I strive to provide an environment where my clients feel welcomed and safe to process life events, develop awareness, and gain insight about themselves. I believe therapy is a collaborative process where the therapist may provide the client useful tools to strive to live a more fulfilling life. The healing process is usually a gradual process filled with challenges and it tends to become more difficult before you are able to see the fruits of your hard work. I believe people are very resilient and with a little guidance and the right tools, they can learn to build their skills towards a healthier way of living. I look forward to walking alongside my clients in their journey towards healing.

I earned my bachelor’s degree in Psychology from California State University, Fullerton and graduated from Azusa Pacific University with my Masters of Arts in Clinical Psychology with an emphasis in Marriage and Family Therapy. I take on an eclectic approach in therapy depending on the client’s needs, but usually lean towards Cognitive Behavioral Therapy, Dialectical Behavioral Therapy, and Person-Centered approaches.

Areas of Expertise: Young Adults, Anxiety, Depression, Trauma, Faith and Spirituality

Nicolette Manzo

Associate Marriage and Family Therapist

Nicolette Manzo, MS

My approach to therapy is focused on cultivating a space of healing through curiosity, connection, humor, and open and honest discussion. I provide a space where you will feel both challenged and wholly supported. Together, we can work to understand, navigate, and address any challenges you may be facing.

In my previous experiences, I have worked with adolescents, their families, as well as adults in the community mental health and school settings. I have enjoyed walking alongside individuals and families from a variety of identities, cultures, and faith backgrounds while providing a safe, nonjudgmental environment. While I ensure that therapy is tailored to each person, my general approach is from a trauma informed, cognitive behavioral lens.

I attended Louisiana State University where I obtained a bachelor’s degree in Psychology with a minor in Social Work. I later earned my master’s degree in Counseling with a specialization in Marriage and Family Therapy from California State University, Northridge.

Areas of Expertise: Adolescents, Young Adults, Anxiety, Depression, Trauma, Self-Esteem, and Relationship Issues.


Associate Marriage and Family Therapist

In life we go through many different experiences. Some are pleasant and some challenging. These experiences shape us into the unique individuals we are and will continue to grow into.

These therapists are typically students in the early phases of their graduate education, having completed less than two years of clinical training. However, they have completed a significant amount of clinical and classroom work, and a licensed Marriage and Family Therapist, a licensed Clinical Psychologist, and/or a post-doctoral clinician supervises their work.
