On The Job

As a teenager, Dr. Susan Yohn worked as a kennel assistant with a small-town Iowa veterinarian who showed her the long-term joy and satisfaction that comes from working in the veterinary profession. As an internist, she loves the challenge of solving diagnostic mysteries and is thrilled when she helps a pet recover. She feels her niche is diagnosing and “tweaking” long-term cases with medical, dietary and supplement therapies. Dr. Yohn is skilled in all aspects of veterinary internal medicine to include gastrointestinal, liver, renal, respiratory, cardiac, hematologic and oncologic cases.
