I would like to make an addendum to my entry of June 18th. At that time there were problems with the patient portal system and the telephone voice mails in Dr. Kalvaria’s office. Once I was able to talk with Dr. Kalvaria I felt very comfortable with him and his expertise. In fact, due to his experience and attention to detail he found a very small growth in an unusual area and it was able to be removed before it could create major problems. One never knows but this thoroughness may well have sa

I spent 2+ yrs, $20,000 in prescriptions and my issues are the same. I complained to his staff never received a response. I had to threaten them to get my records. Not so helpful since this doctor is a mbr of the Florida Digestive Health Physicians group, Dr. Lee Mitchel refused to see me because I had been a patient of dr. Kalvaria. Restraint of Trade comes to mind! A shock to me that another referred doctor would not see me because I fired a member of their group. Stay from this whole group
I reviewed this patient's chart. I made a number of recommendations which worked for him. Unfortunately due to his medication coverage the medications which worked were expensive. This is a problem that prescribing physicians are facing increasingly and have no control over. Since he is having trouble finding another gastro-enterologist in the area, I will be happy to see him back and continue to try to resolve his gastro problems

Dr Kalvaria is a competent physician, however the office is so poorly run that it could put your health at risk. In addition to being disorganized, the attitude of the staff is dismissive, somewhat careless, and bordering on a lack of respect for patients. Just getting through to the office staff is next to impossible. You leave voicemails only (no humans available) and someone may or may not return your call. The office administration is unreliable.
Due to recent retirement of 2 gastroenterologists we have been flooded with new patients. My partner and I are trying to recruit a new doctor and increasing our staff. For existing patients, we strongly encourage you to register for the patient portal which allows you to communicate with us bypassing the telephone system

Although Dr. Kalvaria was excellent along with his anesthesiologist Dr. Sunday his staff is completely INCOMPETENT. At the time of my procedure I was incorrectly charged hundreds of dollars and still have not received a refund yet have been sent overdue bills that the office said was a mistake. Over a dozen phone calls to staff have NEVER been returned. I received the wrong orders for the lab and had to spend an entire day getting the correct paperwork in which I actually had to go to his off

I had a very complex colon polyp situation, and Dr. Kalvaria was able to keep me from having my colon removed. I have found him to be an excellent diagnostician, and he has been a friendly and caring physician.

Dr. Kalvaria is fantastic...his staff is not.

Dr. Kalvaria has been my gastroenterologist for several years. The level of care is outstanding. He takes the time to explain conditions and procedures fully with recommendations for self care. He seems to connect with patients on a personal level. I mentioned once that I often had leg cramps after hard exercise. He said he takes yellow mustard, which contains soluble magnesium. IT WORKS!! My favorite anecdote from any doctor I ever visited, it was totally candid and I am grateful.

I highly recommend Dr. Kalvaria. I had a consult with another physician who recommended surgery. Dr. Kalvaria was thorough in exploring other options first and I am now successfully in remission with medication and surgery isn't needed.
