Addiction therapists & psychiatrists in Walnut Creek, CA

I work with adults struggling with anxiety, depression, addiction, relationship challenges, and major life transitions. Many of my clients are professionals who appear successful and capable on the outside but privately feel overwhelmed, disconnected, or stuck.

I also work extensively with men and husbands who have spent years believing they should be able to handle life's challenges on their own.

Before becoming a therapist, I spent more than 25 years in engineering and organizational leadership. That experience gives me an appreciation for the pressures of work, relationships, family responsibilities, and the challenge of balancing competing demands while trying to keep everything together.

Anxiety and perfectionism have turned your mind into a battleground. Your inner critic nitpicks every interaction, leaving you exhausted by thoughts of “Damnit, why can’t I just be better!” Painful memories get louder, no matter how hard you try to ignore them. Daily invalidations of your Latina, queer, or immigrant identity sting, and you feel isolated as you keep your suffering to yourself. You’ve tried everything: doom scrolling, drinking, and self-help books, but nothing has worked. You're left feeling hopeless and weighed down.

I’m passionate about helping those who need help mentally and emotionally

Hi! My name is Peter Sherlock, and I’m a licensed clinical psychologist (PsyD) practicing in the San Francisco Bay Area, though I see clients statewide via telehealth. My approach to therapy is warm, focused, and tailored to your needs. I will support you every step of the way as you develop the skills you need to live life in a way that feels right to you. My main areas of focus are depression, anxiety, mood disorders, and addiction.

My passion is to help others find more joy and meaning in their lives. I work creatively and collaboratively with adults, teens, and children to explore the heart of the matter. I have experience working in the schools, with a team at a counseling clinic, and in private practice. I specialize with teenagers and their families and moving into couples work as well.

I have found a calling that allows me to bring my full self – head, heart, and soul – to my work.

I found this calling after a fulfilling career in social services. In addition to working as a teacher, program manager, policy advocate, and peer counselor, I have also married, raised a family, coached youth sports, and pursued mindful self-care, creativity, and personal growth.

I earned my Bachelor’s in English from Harvard and my Master’s in Counseling Psychology from The Wright Institute.

I'm an open minded individual and welcome any topics in treatment

I am a Licensed Clinical Social Worker (LCSW) and Certified Alcohol and Drug Counselor (CADC II) with over 25 years of experience supporting individuals, couples, and families as they navigate life and the concerns that arise.
