What People Say About Dr. John Marcellus, MD
RecentHighestLowestMost Helpful

I used to like Marcellus. He’s a very good and thorough doctor. However, the patient wait time is ridiculous. You could have an appointment scheduled for 3 and won’t be seen until 5. And that’s on a good day. He cares immensely for his patients but needs to manage his time slots better. One time, I was 15 minutes late to my scheduled appointment with him. When it was my turn, I had already waited an hour and a half after my scheduled appointment time to see him, and they were going to skip me (and make me wait longer) and let the next patient go ahead of me. Because they were on time for their appointment. Luckily, the other patients were well aware of his lateness so they let me go. I understand that he has a lot of patients that need to be seen and taken care of, but maybe manage the schedule a bit better, and don’t schedule so many appointments in one day.

Most unhelpful in getting refills for my son. It took over 3 weeks, multiple phone calls. They still did not get it right. I finally found the script at the wrong pharmacy and had it transferred to where I originally wanted it.

I can't say enough wonderful things about Dr. Marcellus. My past experiences with therapists often felt like awkward interviews (stuffy, too serious, straight-faced etc). But with Dr. Marcellus I feel very at ease and conversation flows naturally. I never find myself over analyzing or over-thinking before every response I give. I can speak very freely, which I think really helps to solve the real issues. He is always VERY professional, but in a warm, genuine way. He has helped me tremendously.
