Book a therapist or psychiatrist in Walnut Creek, CA covered by Aetna

Hi, I'm Mitch — a psychiatric mental health nurse practitioner with a Doctor of Nursing Practice from Vanderbilt University. San Diego has been home since 2020, when the Navy first brought me here.

My background includes pediatrics at Children’s Hospital in St. Paul, inpatient psychiatry in Nashville and San Diego, crisis stabilization, and outpatient mental health care. I’ve worked with veterans, college students, LGBTQ+ individuals, people experiencing homelessness, and patients navigating anxiety, depression, bipolar disorder, ADHD, trauma, substance use, and severe mental illness.

I primarily provide psychiatric evaluation and medication management while integrating supportive therapy, psychoeducation, and practical coping strategies into visits. My approach is collaborative, direct, and grounded in helping people improve day-to-day functioning and quality of life.

I look forward to getting to know you.

I've been in private practice for 12 years and work with young adults aged18 - 30. I’ve always been interested in the way our experiences, relationships, beliefs, and thought patterns shape the way we see ourselves and the world around us. This interest led me to begin my career by working with an anti-human trafficking organization providing resources and aftercare services for rescued and recovered teen girls. I’ve also worked for local school districts as a high school special education crisis counselor and in-class behavior interventionist.

Outside of the therapy room, I enjoy spending time with my family, staying active, and continuing to learn about health and whole-person wellness.

I have completed a MA in Counseling Psychology. I have worked with diverse populations covering many issues. My approach is client focused through active listening skills and empathic support.

I am a licensed Marriage & Family Therapist (LMFT) providing telehealth services to clients in California. With over 25 years of experience, I firmly believe that my clients are the experts in their own lives. My role as a therapist involves understanding and respecting my client’s experiences and collaboratively developing tools to support their ongoing journey.

I work with individuals seeking therapy for anxiety, depression, grief, women's issues, trauma/PTSD, and chronic illness/pain challenges. I'm experienced in treating relationship and family challenges. I maintain a body-positive, sex-positive, and LGBTQ+ friendly approach, welcoming different lifestyles without judgment.

Sometimes you don’t need someone to simply ask, “And how does that make you feel?” You need a therapist who can listen, understand the bigger picture, help you connect the dots, and work with you on what to actually do next.

That’s the kind of space I strive to provide.

I work with adults who may look like they’re holding everything together while privately feeling overwhelmed, anxious, exhausted, angry, disconnected, grieving, or simply tired of carrying so much. Some of my clients come to therapy because of a specific crisis or life transition. Others arrive saying, “I don’t even know where to start—I just know something needs to change.” Both are perfectly valid places to begin.

I’ve dedicated much of my life to the mind body connection, holistic wellness and creating balance. I am fascinated by how small changes can make such a big impact on someone’s life. I work with individual clients.
