What we do

Our Services

Medical Care

We offer the highest level of medical care for your dog or cat.  If your pets’ needs are outside of the scope provided in our clinic, we offer a network of provider partners.


Part of being healthy is being clean and groomed.  We offer an in-house grooming service to keep your pet looking and feeling its best.


Not all vets are equipped and staffed to board animals safely.  We offer boarding services, however we only board our feline patients and animals that we have seen and certified as healthy and at no risk to others. Boarding is not available over holidays.

Support to Rescue Agencies

Dr. Diesel and his team are proud of the work that they do with Pet Rescue agencies around the St. Louis Metro area.  Weekly we treat rescues and prepare them for adoption.  Our services for these agencies are deeply discounted if not donated in some cases.

What Drives Us
