Addiction therapists & psychiatrists in Petaluma, CA

I'm Candice Jeffers, a board-certified Psychiatric Mental Health Nurse Practitioner with an unusual background—I spent nearly a decade in cardiovascular critical care before dedicating myself to mental health. That ICU experience taught me something crucial: psychiatric crises deserve the same urgency, expertise, and unwavering support as any cardiac emergency.

For nine years at Ascension Seton Medical Center's Cardiovascular ICU, I supervised teams through impossible situations. I learned to stay steady when everything felt uncertain, to read the subtle signs others might miss, and to offer hope when families needed it most. Those years shaped how I practice psychiatry today—with precision, presence, and profound respect for what you're facing.

I completed my Master of Science in Nursing at University of South Alabama in 2024, immersing myself in over 600 clinical hours spanning outpatient clinics, inpatient psychiatry, and crisis intervention. My pediatric nursing background adds another layer—I understand how early experiences shape us and how differently mental health shows up across ages.

My practice centers on thorough psychiatric evaluations, personalized medication management, and crisis intervention for all ages. I specialize in suicide risk assessment, trauma-informed approaches, and evidence-based treatments that actually fit into real lives. I'm MOUD-trained and licensed for telehealth in Texas, California, Arizona, and Florida.

Here's what matters most: I approach mental health as someone who's held space for both miracles and heartbreak. I know seeking help requires tremendous courage. I know healing rarely follows a straight line. And I know you need a provider who won't flinch, no matter what you share. My work blends critical care decisiveness with deep compassion—because you deserve both.
