Patient Reviews

Patient

This review has been a long time coming. I am extremely disappointed in this doctor and his "treatment" provided. I was becoming increasingly frustrated because each time I would leave his office, I would leave crying. I begged him constantly to listen to me and everything just came back to "change your diet and exercise more." I was frustrated by this because, as a former runner and boxer having lost more than 60 pounds, I knew the symptoms I was having were not from me being gluttonous. I tried over and over again to explain my symptoms and tell him what was wrong and he refused to believe it was anything other than me needing to change my diet to something Mediterranean-focused. Low fat dairy, fish, whatever, etc. This was especially concerning because, when treating someone with an autoimmune thyroid disease, he should know that low-fat and dairy products in general can actually trigger the autoimmune response. His Mediterranean wonder diet was actually more detrimental to my health than how I was consuming food previously. Additionally, each appointment, after begging for help and basically being called a liar, I would get very upset. It was at that point that he wanted to take my blood pressure. He would get me upset to the point of tears and then record the blood pressure in my chart - and decided that it was off of that reading he would diagnose me with high blood pressure and prescribe me medication. I was livid. You do not give someone without high blood pressure medication for high blood pressure! The office was nice enough but is extremely behind in their billing. Nearly 6 months after I was no longer a patient I got a $600+ bill from their office. I would recommend that unless you have no other choice, find a different doctor. This guy is a quack.

I have never had a Doctor actually go line by line reviewing the health questionaire I filled. He spent over an hour with me and it was the most comprehensive physical I have ever had. I was very pleased and his staff is very friendly and helpful.
