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.


Raenn Thomas, Veterinary Technician












I live in Edwardsville with my large, extended family of humans and animals who I love and care for.  I have been working in the veterinary field for over 20 years, and I am currently enrolled in school working towards becoming an CVT in the state of Illinois.



Robyn Martin, Office Manager




I have worked in the Veterinary industry as a receptionist for over 18 years. My background was in the Customer service/Retail industry. But I have always felt at home, once I was able to work in this field  helping animals. I have had countless cat and dog rescues over the years.  I currently have 1 dog Bugsy and 5 cats. My animals are my furbabies, however I do have my niece Kelsea and her 2 year old son Liam that live with me. He keeps us on our toes.
