About Dr. Mark G. Agresti, M.D.
Board-Certified Psychiatrist | 30+ Years Experience | Palm Beach, FL
A Psychiatrist Who Actually Knows Your Name
Dr. Mark G. Agresti, M.D. is a board-certified psychiatrist and psychotherapist with 30+ years of experience treating the full spectrum of psychiatric conditions — from depression and anxiety to treatment-resistant cases, complex psychopharmacology, addiction, and ADHD.
Based in Palm Beach, Florida, Dr. Agresti has built his practice around a simple but radical idea: you should be able to reach your psychiatrist directly. Not a nurse. Not a patient portal. Not an answering service. Dr. Agresti himself — by text or phone — whenever you need him.
His practice model is what the industry calls "concierge psychiatry," but Dr. Agresti's version comes with no annual membership fee. You pay only for the care you receive. The concierge access — direct cell number, 24-hour appointment availability, same-day prescription refills, text messaging — comes standard.

Treatment Philosophy
Dr. Agresti practices integrated psychiatry — combining psychotherapy and medication management in one provider. Most psychiatrists today see patients for 15-minute medication checks. Dr. Agresti takes a different view: the best psychiatric care is comprehensive, ongoing, and personal.
His approach is medically rigorous and scientifically grounded, but delivered with the warmth and accessibility of a family doctor from a different era — one who knew his patients, knew their families, and was reachable when something went wrong.
For complex cases — treatment-resistant depression, polypharmacy, patients who have failed multiple medication regimens — Dr. Agresti brings 30+ years of psychopharmacology expertise to bear. He has managed cases that other psychiatrists have declared untreatable.
The Concierge Model — No Membership Fee
Concierge medicine typically means paying $2,000–$10,000 per year for premium access on top of regular fees. Dr. Agresti's model is different. There is no membership fee, no annual retainer, no monthly subscription. The direct access, the same-day refills, the direct cell number — these are not premium add-ons. They are how Dr. Agresti has always practiced medicine.
