About Jen

Jennifer Gregg is a California-licensed psychologist, author, professor, and trainer. She has a Ph.D. in clinical psychology, with specialized training in behavioral medicine and psycho-oncology. She has over 25 years of experience working with patients who are sad, scared, traumatized, stuck, and who want to find a way to live differently in the face of challenges.

Dr. Gregg's psychotherapy training and approach is focused heavily on evidence-based therapy, with an emphasis on Acceptance and Commitment Therapy (ACT). ACT helps people stop avoiding difficult feelings and live a full life. She studied with the originator of ACT, Dr. Steven Hayes, and is a recognized peer-reviewed trainer in ACT ( here is a recent article about ACT from the Washington Post that she was featured in.)

Therapy is a warm, caring relationship where patients can safely experience their thoughts and feelings in order to be able to build skills to better manage them in their lives. In therapy, Dr. Gregg's clinical approach utilizes mindfulness and evidence-based interventions, with a strong focus on helping patients live in ways that are consistent with their personal values.

Training and Background

Dr. Gregg received her clinical internship training at the Palo Alto Veterans Administration with a specialization in behavioral medicine in 2003, and has served in multiple professional and consulting roles working with PTSD and cancer in veterans within the Veterans Administration.

Since 2005 she has also been a full-time professor in the psychology department at San Jose State University. In addition, she served as a psycho-oncologist at the San Mateo Cancer Care clinic, part of the UCSF Helen Diller Family Comprehensive Cancer Center, in a clinic where she worked as a psychologist with cancer patients and their families for nearly 15 years.

Throughout her career, Dr. Gregg has conducted research on ways to live with more meaning, connection, and awareness, both in the context of serious medical illnesses and in the handling of everyday stressors. She has authored or co-authored two books for the public and dozens of research publications in my field.
