I believe deeply in the power of words and how they shape our mental and emotional well-being. My work is rooted in speaking life, clarity, and hope into spaces where patients may feel discouraged or stuck. I work with all adults who are seeking thoughtful, intentional, holistic care.

Headway makes it easy to find support for your mental health — from finding the right provider, to understanding costs, to scheduling with ease.
Finding psychiatrists in San Jose starts with understanding the type of mental health care you want. Psychiatrists and psychiatric mental health nurse practitioners can diagnose mental health conditions, prescribe medication, and provide medication management. Therapists provide talk therapy and support through approaches like cognitive behavioral therapy, dialectical behavior therapy, or trauma-informed care. If you are looking for care related to anxiety, depression, ADHD, bipolar disorder, or OCD, review each psychiatrist’s listed specialties, training, and care approach to see whether their experience matches your needs.
San Jose offers access to psychiatrists across a wide area, including nearby communities like Campbell, Cupertino, and Los Gatos. Location, appointment format, and scheduling can shape which psychiatrist is a practical fit. Some people prefer in-person visits close to home or work, while others choose virtual appointments for more flexibility. Psychiatric medication management appointments are often shorter and less frequent than therapy sessions, and some psychiatrists also offer therapy. Some people work with both a therapist and a prescriber, so it can help to read bios for details on session structure, availability, and communication style before booking.
Psychiatric care in San Jose can be a significant expense without insurance. Using in-network insurance is one of the most reliable ways to reduce session costs and understand what you may pay before your first visit. Headway helps you search for psychiatrists who are accepting new patients, check whether they take your plan, and view estimated costs before you book. You can compare specialties, read profiles, and choose a psychiatrist who fits your needs, schedule, and insurance coverage.
If you're already taking psychiatric medication and considering switching providers, talk to your current prescriber before changing or stopping any medication — most psychiatric medications shouldn't be stopped abruptly. Anyone experiencing thoughts of self-harm or in acute crisis should call 988 or go to the nearest emergency department rather than wait for an outpatient appointment.
