Mental health has long been treated as the forgotten side of healthcare — and for me, that's exactly why it matters so much. As a Psychiatric Nurse Practitioner serving clients across California through telehealth and in-person care, I specialize in helping people navigate depression, anxiety, and ADD/ADHD. I believe that when mental health struggles go unaddressed, everything else in life suffers — and that healing is not only possible, it's necessary. When I'm not supporting my clients, you'll find me out in nature, getting lost in a good movie, or discovering new music — small reminders of the joy and balance I encourage my clients to find for themselves.
My name is Dianne Fontaine, MSN, APRN, and I'm a Licensed Psychiatric Mental Health Nurse Practitioner, Board Certified (PMHNP-BC) by the American Nurses Credentialing Center (ANCC). I obtained my Master’s Degree from Walden University and has undergone advanced clinical training, equipping me to assess, diagnose, and treat a spectrum of psychiatric illnesses, as well as provide psychotherapy.

Welcome. I’m Karen, a Licensed Marriage and Family Therapist (LMFT). I work with adults and adolescents who are navigating challenges such as depression, anxiety, trauma, relationship stress, and major life transitions.
My approach is collaborative and strengths-based. I support clients in developing healthy boundaries, strengthening communication skills, and identifying coping strategies that genuinely fit their lives. Together, we work toward healing, personal growth, and greater emotional balance.
I strive to create a safe, supportive space where you feel empowered to explore your experiences, reconnect with your strengths, and move through life’s challenges with confidence and intention.
I am a compassionate and dedicated psychotherapist who values creating a genuine, trusting connection with each client. I believe therapy works best when you feel safe, understood, and able to be your authentic self.
I earned my Master of Arts from National University and completed doctoral-level training at Pacifica Graduate Institute. My clinical training and professional experience have provided me with a strong foundation in working with individuals from diverse backgrounds.
I have experience working in drug and alcohol rehabilitation settings, where I supported individuals navigating substance use, trauma, and related mental health challenges. I also have experience working with men’s mental health concerns, including emotional regulation, identity, and relationship issues.
I use an integrative approach, drawing from Cognitive Behavioral Therapy (CBT) and Psychodynamic Therapy to help clients understand both present challenges and underlying patterns. I work with individuals experiencing anxiety, depression, stress, trauma, relationship concerns, and life transitions, helping them build insight alongside practical tools for lasting change.
Outside of my work as a therapist, I value staying active and maintaining a strong mind-body connection. I spend much of my time weightlifting, boxing, practicing jiu-jitsu, and participating in CrossFit and Olympic lifting, and I also enjoy running. These practices help me stay grounded and bring a perspective of discipline, resilience, and balance into my work with clients.
