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.

Headway makes it easy to find support for your mental health — from finding the right provider, to understanding costs, to scheduling with ease.
Finding the right psychiatrist in Sunnyvale starts with understanding the type of care you need. Psychiatrists are medical doctors who can diagnose mental health conditions, prescribe medication, and monitor how those medications are working over time. If you're looking for help with anxiety, depression, ADHD, bipolar disorder, or other mental health concerns, a qualified healthcare professional can help you understand what type of care may be appropriate for your needs. Psychiatric nurse practitioners (PMHNPs) can also evaluate, diagnose, and prescribe medication, and are another provider type available through Headway.
With many mental health providers practicing across the South Bay, narrowing your search can take time. Consider what matters most to you — whether that's a provider who specializes in a specific condition, offers virtual appointments, or is located near your neighborhood in Sunnyvale. Reading a provider's bio can help you understand their approach and decide if they're a good match before you book.
Psychiatry in Sunnyvale and the broader Bay Area can be expensive without insurance. Using your in-network benefits is one of the most reliable ways to lower your out-of-pocket costs. On Headway, you can enter your insurance details to see estimated session costs upfront, and your out-of-pocket expense may be as low as $0 per session. Nationally, Headway partners with over 100 insurance plans, making it easier to find a psychiatrist who is both the right clinical fit and covered by your plan.
