Care Philosophy

In our office, we strive to make sure we meet the patient s needs no matter what. The doctor will spend as much time with the patient as needed. We try to address all of the patient s needs in a timely manner. Our office does not have a very long wait time as far as seeing the doctor and we always try our hardest to work in patients that are sick. The doctor is on call every night after the office closes at 5 and if he is not on call there will be a doctor there to answer your needs.

in Kenneth City Florida |
He is the most genuinely caring about his patients and the health of the community as a whole. He volunteers his time; goes out of his way to be thorough. He is responsible for keeping many people in good health, including me. God bless he and his family

love the doctor, stopped going due to staff. three times i went and found the nurse pounding upon and yelling at her computer. had my doubts. doctor was impressive. returned, blood draw, why they didn't do it immediately, never know. same computer pounding nurse attempted draw. after four blood draw attempts and a rude "gee, guess it's just not my day" comment requested they call me when they get someone who can draw blood. never received call back, guess they never fond one.

Dr. Nirmalan has been my doctor for years and he is the most kind and compassionate person. He treats you as if you were family. I highly recommend him if you need a highly qualified doctor!

Dr Nirmalan was my PCP for about 10 years. He was always caring and compassionate. I just changed PCP as I moved out of county by would highly recommend him to others.

The furnishings in the waiting room are outdated and the Christmas tree and decorations are still up in the waiting room. I have been there at least 5 times and I have yet to see the nurse wash her hands before or during interactions with patients. Some of the exam rooms do not even have a sink and the phlebotomy sink was full of supplies and rusting.
in St Petersburg, FL |
Seems like every appointment I had compiled a list of issues needing attention, Rxs that needed filled, etc. And repeatedly a couple of those items were not addressed. I gave benefit of the doubt earlier when he faced personal grief but as time went on I lost confidence in the practice. Very understaffed to the detriment of patient care.
