Dr. Duda Jr's bio

This content was provided by Dr. Duda Jr "Born and raised in Chicago, Illinois, Dr. Duda gravitated in his early years of education to mathematics and the basic sciences. A product of middle class parents of Polish and Italian ancestries, his childhood was steeped in tradition and culture and an impetus to succeed in school. Attending Weber HS proved preparatory for entrance to Illinois Benedictine College, a school reputable in the basic and natural sciences achievement. Graduating Summa Cum Laude with a BS in Biochemistry, he thereafter sought and received admission to Northwestern University Medical School. Completing a rigorous four years of study in downtown Chicago, Dr Duda matched and ultimately spent 6 years at the Mayo Clinic in Rochester, MN, finally completing fellowships there in Internal Medicine and Endocrinology. His first employment was at Smith-Glynn-Callaway Clinic in Springfield, MO, where he founded the Department of Endocrinology and ultimately spent 23 years before relocating to Tulsa to be part of the team of endocrinologists at the Oklahoma Heart Institute in early 2010."

Patient Comments (6)
I have had Type I diabetes for 47 years and Dr. Duda is one of three endocrinologists I have seen who is an expert in the field. His explanations and answers are very informative and helpful to patients who desire making the best decisions for their health. I appreciate Dr. Duda's expertise and kind personality.

Dr. Duda is a straight shooter who has my health as his top concern. He is up on history when he enters the room. Have had a few glitches in getting prescriptions worked out through insurance, but hear that is par for the cause these days. Glad to have him as my Endocrinologist and glad he chose to practice in Tulsa. Don't mind a wait time because I know he is giving attention to a patient. Dr Duda is a great Doctor. I'd give six stars if I could!

Dr Duda is very nice. Takes the time to really get to know you, answers questions, and is very knowledgeable. Being the first time I saw him I was thoroughly impressed and glad to be one of his patients.

I have never met a more kind compassionate, yet firm and caring doctor, I have been seeing Dr. Duda since 2006. I started seeing him in Springfield MO and continued seeing him when he moved to Tulsa at Oklahoma Heart. I coiuld not recommend him more highly! He is a gift from the Lord!

Very personable and really listens. He wants to treat the whole patient, not just throw medication at a problem.
