I have no words to express how grateful I am with Dr Mark Zelkowitz and his team, honestly I am not a person that leaves reviews, but I want you to know in case you are looking for a great Doctor.
I took my 18 year old daughter who was on peritoneal dialysis to see Dr. Z for a second opinion because her Blood pressure, phosphorous, potassium and more were not under control.
Dr. Z was very knowledgeable, honest and kind, we decided to change Doctors and in a month thank God and the Doctor my daughter’s blood work results are in the range and she finally feels great again.
Thank you Dr. Zelkowitz
