Mark G. Agresti, M.D., LLC — Ketamine Clinic in Palm Beach, FL

I have worked with various psychiatrists since I was 12 years old over the years, and I can say without hesitation that Dr. Agresti stands in a category of his own. His approach to medication management is thoughtful, precise, and grounded in a deep understanding of both the science and the individual sitting in front of him. For the first time, I feel genuinely stabilized and supported — I’m almost tempted to use the word “cured,” which is not a word I use lightly. What sets Dr. Agresti apart is his ability to combine clinical expertise with a level of attentiveness and clarity that is rare in this field. He listens carefully, explains his reasoning, and makes adjustments with intention rather than guesswork. The result has been a level of improvement in my daily functioning and overall, well‑being that I didn’t think was possible. I’m profoundly grateful for the quality of care I’ve received. Dr. Agresti is, without question, the best psychiatrist I have ever worked with, and I recommend him with complete confidence! I would give ten stars if I could ********** -J. Eve Hall

Dr. Agresti is an amazing psychiatrist. He has helped me overcome the battles in my head. He is very diligent and cares for his patients, making sure that my medication regiment was fit for me and that the doses weren't impacting my health in a negative way. Thank you so much for all the help!

When I was out of work and in need of help Dr. Agresti was there for me. I’ve known him for almost 20 years now and he helped me get back on my feet when I needed it the most. Love him for that and would recommend him to my friends and family.

I've worked with Dr. Mark Agresti for over 5 years. I can confidently say that he is compassionate, truthful, and trustworthy while faithfully serving South Florida & the palm beaches. If you're looking for help then look no further! Best in the business in my opinion.

Saved my daughter's life. Dr Mark Agresti is the best. Daughter is 4 yrs sober and loving life.

Dr. Agresti was so helpful in helping my wife detox and withdrawal from alcohol. We worked as a team along with my wife late at night to ensure she had the appropriate vitamins and meds to make sure she was safe. I trust Dr.Mark with my family and our lives. The responsiveness and level of care he provides is unparalleled.

Dr. Agresti knows what he is doing and takes his time with me every time. If you are looking for an excellent doctor that knows medicine and addiction then he is it. very impressed! the office also always calls back right away and helps with anything. So glad I found Dr.Agresti, he came highly recommended from a doctor in Jupiter and now I see why. Thank you Dr.Agresti to you and your team.

I'm not a patient and don't live in florida, but i was reading an article Dr Agresti wrote on the good, the bad and the ugly of lithium. I've been on lithium for a short while and heard such good things and then i started taking it. I was on 300 mg for only a week and I've been sick everyday, migraines all the time throwing up and not sleeping. Im in Chicago and honestly there is a 3 month wait minimum to get in and see a doctor for my depression. So after reading the article i decided to reach out by email with the hopes of getting some advice. Surprisingly dr mark reached back out with some advice and even offered to help treat me. Now being in Chicago i don't see that happening i can't afford a flight to florida and can't afford to take time off of work but the fact that he took time out of his day on a weekend to help me means alot. You can tell he really cares. Thank you for the advice 🙏 and i will look into the advice you have given me.
