Charles Holzner MD is an internal medicine doctor with additional training in endocrinology and diabetes. He chose to pursue additional training in endocrinology because the incidence of diabetes and its complications such as end stage renal disease (ESRD), is high amongst the local population. Dr. Holzner has always been interested in science and was a chemistry major in college. He thought that medicine was a great way to use scientific discoveries to benefit people. And he believes that internal medicine is the most challenging branch of medicine since it covers all aspects of patient care. As an internal medicine doctor, he can do so much to help people live longer and better lives. Dr. Holzner thrives on finding solutions for complex and difficult medical problems.

Dr. Holzner was born in Budapest, Hungary and came to the United States during the Hungarian Revolution in 1956. His wife is from Uzbekistan, where there are only two dialysis units and 35% of the population who are diabetic have no access to dialysis. To help provide greater access to care, he and his wife recently traveled to Uzbekistan to help set up a dialysis center. As a problem solver, Dr. Holzner previously initiated a plan to convert 80% of diabetics to lower cost insulin without causing any complications, and he was integral in starting an ESRD special needs health plan that enrolled 1,800 patients and decreased hospitalizations by 50% below the national average.

Dr. Holzner is an avid skier and tries to go skiing as often as he can.

Well, he wasn't my... my regular physician. So I didn't really go in with many expectations, but I believe that with the level of pain that I was experiencing, I felt like I should have gotten an anti-inflammatory. However, he did give me a cortisone shot. However, I did not feel any subsequent relief. So I feel maybe he just not knowing me as a patient was hard for him, but he, he could of made light of the situation and I was in severe pain.

Dr. Holzner's knowledge of care and maintenance of my personal health is excellent. He is honest, straight forward and has a great "bed side manner" with a super sense of humor which makes dealing with visits much easier. Staff front to back was very good. I would refer anyone to Dr. Holzner but be careful referring to PIH .

This was an appointment that was made for me. My only comment is that I wasn't told in advance that it was a phone appointment. I appreciated it being remote, but I would have liked to have known that in advance.
