Dr. Lelan R. Olsen, DVM

I have been serving the Glen Carbon area as a licensed veterinarian since 2001. I graduated from Kansas State University in 1990, and am a member of the American Veterinary Medical Association. It has been a career goal to provide our community with the current and best medical care for a wide variety of pets. These animals are the essential key in the mental and physical well being of our clients. Without them, many of us would have a much lower quality of life. With that being said, it only makes sense to do our best to keep our pets healthy and happy as well.
