Steffen Sum, Medical Director


Internal Medicine

Dr. Steffen Sum comes from an extensive background in teaching beyond academia, and instilling the best of medical practice to his students. After his intensive veterinary studies at Ludwig-Maximilians-Universität in Munich, his focus included extensive work and ongoing training in urology, diagnostic services, hemodialysis, infectious disease, advanced imaging and endoscopy. He published numerous works on these topics as well as providing high level training and mentoring at University of Georgia for 8 years.

Dr. Sum now provides Small Animal Internal Medicine to our patients at VCA Highlands Ranch Specialty & Emergency Center, offering diagnostic services in ultrasound and endoscopy as well as treating our hospitalized intensive care dogs and cats. He also provides internal medicine consultations on an out-patient basis with complicated medical cases such as advanced diabetes, renal failure and other hormonal ailments.

Having grown up in the Black Forest of Germany, he has now completely fallen in love with our Colorado outdoors, where he hikes as well as enjoying horseback riding and his motorcycle rides.

As Medical Director, Dr. Sum serves to assure that the highest veterinary medical care is followed throughout the entire VCA Highlands Ranch team.
