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.

Hello, my name is (PHI removed), I've been a patient of Dr. Holzner's and he's always done very good by us. If he, you know, sends us to a specialist if he thinks that we need to be, and we don't have to really, you know, spend a lot of time asking for that because he seems to know - he's a good doctor. I really have a lot of faith and trust in him. Alright, thank you. This is (PHI removed) - bye.

The Doctor answered very important questions I had regarding my recent heart surgery! He had lab results and shared information freely holding back nothing. I was very happy with the results from the surgery and results from the lab.

-This was a telephone appointment as a follow-up to surgery received on Jan 27 at PIH Whittier. Before this I had never spoken to Dr. Holzner, however I found his fed back and concern most helpful. More than this, I appreciate PIH for their post-op procedures. Thank you. (PHI removed)

I really want to the thank the Medical Assistant that helped me on the day of my visit. I didn't get her name but she was very sweet and answered any questions. Her attentiveness was amazing and she made me feel comfortable. Thank you to Dr. Charles Holzner for seeing me in a timely matter and also answering all the questions I had. I was very pleased with all the staff from the beginning to end. Thank you all for your hard work.

This is a doctor that called me after I was discharged for the hospital. I never physically met him. So, the advice he gave me was all over the phone. I hope to have a follow up call for next week.

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.

Concerned that provider wasn't wearing face mask appropriately, given that there's a high surge of covid cases. He was only covering half of his mouth and chin.
January 04, 2022
His response to all my concerns was I was fat. I know am not the ideal weight. I am dealing with depression and I explained that to him. So to keep reminding me of my weight was not helpful actually kinda hurting my mental health. I was in a car accident and I know from a MRI I have 4 areas of my lower back messed up. Asked about options to relieve my pain. I already go to a chiropractor. His response lose weight. The numbness and random shooting pain effects my quality of life.

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.
