Hello and welcome. Entering therapy is not always easy, but an important step towards change. I believe that therapy should be a collaborative process that both my clients and I work on as a team. Trust, empathy, experience, and education are key components to successful treatment that produces long term sustainable results. I hold a B.S. in psychology with an emphasis in law and criminal behavior, a M.S. in clinical psychology, and a Psy. D. I am a Clinical Psychologist licensed in California and in Arizona. My training and experience in forensic, hospital, inpatient, and private practice settings allows for a wide range of therapeutic experiences that allows for a wide range of treatment interventions with my clients. I am CBT (cognitive- behavioral) and DBT(dialectical- behavioral), and ACT ( Acceptance and Commitment) trained. I believe in evidence based treatments that will provide long term change. I am a Clinical Psychologist licensed in California and in Arizona. I have been in practice for over 15 years with my practice focusing on Addiction, ADHD, Mood Disorders, Anxiety, Depression, Trauma, and PTSD.

My husband and I have talked to several couples counselors and Jennifer has been the best. She’s given us steps to communicate better while in conflict. We are very grateful.

I love Jenn. We have worked together for a while now and she's always great. I feel better after each session and empowered to tackle the challenges that I'm in therapy for (as well as anything else I can think of).
