Meet Our Board-Certified Ophthalmologist

Our Physicians

Ophthalmology Ltd. was founded in 1968 with a revolutionary approach—bringing together a team of doctors with expertise in a wide range of subspecialties would make it possible to deliver truly comprehensive eye care to residents of Sioux Falls and surrounding communities.

Time has proven the wisdom of this approach. Now, more than 40 years later, our staff of highly qualified physicians, nurses, and assistants have made Ophthalmology Ltd.’s name synonymous with the highest quality of comprehensive and specialized medical and surgical eye care.

“Our staff is extremely competent. If I see a patient that needs more expertise in a certain area, I know I can bring in another doctor from our staff and be confident my patient will get the best care possible.” - Dr. Richard Tschetter, MD
