James M. Kemmerling, M.D.

Board-Certified Surgeon and Vein Specialist

Dr. James M. Kemmerling, M.D., F.A.C.S., is a board-certified surgeon who specializes in vascular surgery. He is a registered vascular technologist, is certified in venous ultrasound, and is a Fellow of the American College of Surgeons. He has experience with vascular procedures like carotid endarterectomy, aortic resection for aneurysm, aorto-bifemoral bypass, femoral-popliteal bypass, and femoral-distal bypass. 

Prior to his work with United Vein Centers, Dr. Kemmerling owned and operated a vein clinic in Green Bay, Wisconsin where he performed minimally- invasive procedures such as endovenous laser ablation, radiofrequency ablation, microphlebectomy, and sclerotherapy. While he enjoyed operating his own practice, Dr. Kemmerling enjoys being able to focus more on patient care with UVC and less on the business side of running a medical office.

A veteran of the United States Air Force, Dr. Kemmerling served as an active duty general surgeon for several years at the start of his medical career. He has a great deal of surgical experience in both private practice and hospital settings. He served as the Medical Director of Bariatrics at Aurora BayCare Medical Center where he established the Bariatric Center of Excellence. He was on staff at four hospitals in the Green Bay area for two decades.

Dr. Kemmerling graduated magna cum laude from the University of Wisconsin with a Bachelor of Science degree in biochemistry. He received his Doctor of Medicine degree from the Medical College of Wisconsin. He completed his residency at Wright State’s Integrated Surgical Residency program.
