About Dr. Jennifer Lewis
Beginning therapy often comes at a moment when something no longer feels sustainable — whether you are feeling overwhelmed, navigating a transition, experiencing strain in your relationships, or trying to make sense of changes that feel difficult to manage alone. You may be looking for greater clarity, a different way of coping, or simply a space to slow down and feel more grounded in your day-to-day life.
I am a licensed clinical psychologist providing individualized and group psychotherapy for adults in New York and New Jersey.
Professional Background
My clinical background includes extensive work informed by a health psychology perspective, supporting individuals navigating the psychological impact of medical illness as well as more general mental health concerns.
My work is grounded in a health psychology perspective, with a focus on supporting individuals navigating anxiety, life and work transitions, relationship concerns, and the emotional and psychological impact of medical illness.
I approach therapy as a collaborative and thoughtful process—one that offers both space for reflection and the development of practical, effective strategies. My goal is to create an environment that feels supportive, steady, and responsive to your individual needs; while helping you move toward meaningful, sustainable change.
Biography
Dr. Jennifer Lewis is a doctoral-level clinical psychologist whose work integrates evidence-based psychotherapy, health psychology, and psycho-oncology. Originally from Oxford in the United Kingdom, she completed her undergraduate training in London and earned her Master’s and Doctor of Psychology degrees in Clinical Psychology at the California School of Professional Psychology, with an emphasis on multicultural issues.
She brings a breadth of experience from private practice, educational settings, and medical and community-based environments on both the East and West Coasts. Her clinical work has included public and private medical settings, as well as schools and community mental health systems. In these varied settings, she has worked with diverse populations throughout the lifespan, with attention to the cultural, interpersonal, and health-related factors that shape experience.
Dr. Lewis provides thoughtful, individualized care for adults navigating cancer-related experiences, chronic or serious illness, caregiving roles, and life transitions that bring emotional, psychological, and existential complexity. Her work at the intersection of health psychology and psycho-oncology supports individuals in making sense of change, managing distress, and engaging in reflective psychological work that fosters resilience, meaning, and quality of life.
Her clinical approach is grounded in collaboration, cultural responsiveness, and respect for each person's lived experience. She draws from cognitive-behavioral, acceptance-based, and mindfulness-informed approaches, as well as trauma-informed and meaning-centered frameworks, tailoring treatment to the needs and pace of each individual.
In addition to psychotherapy, Dr. Lewis brings extensive experience in clinical consultation and interdisciplinary collaboration, having worked closely with physicians, healthcare teams, and institutions to support psychologically and medically nuanced care.
She has been affiliated with NYU Grossman School of Medicine, NYU Langone Psychiatry Associates and the Perlmutter Cancer Center, where she provided individual psychotherapy services and worked within multidisciplinary medical settings to support integrated, patient-centered care.
Her practice is grounded in the belief that psychological care should be both clinically rigorous and deeply human. She offers care through both in-person and telehealth formats, as appropriate, and welcomes individuals at all stages of health-related experience and life transition.
