Services
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.
Olsen Veterinary Clinic is proud to provide exceptional care to the Madison County, IL area. Dr. Olsen is one of the few vets in the area that is trained to treat larger farm animals such as horses and cows. Since the office is not conducive to treating larger animals in house, Dr. Olsen is happy to come to you to take care of the health of your animal.
The most common MLS Therapy indications are pain relief, intervertebral disc disease, post surgical pain relief, degenerative joint disease, wound healing, arthritic conditions, muscular/skeletal system trauma, and inflammatory conditions. MLS therapy uses both the 808nm and 905nm wavelengths simultaneously.

PLEASE! If you do anything, do NOT take your pet to this clinic. The staff is negligent and blatantly lied to my face. I was told my dog had her parvo and rabies shot when in fact they just never did it. They were then appalled when I questioned why I was lied to and I was hung up on. The service is awful, the communication is awful, and the care was awful. I could write a novel, but please love your pet and do better than this place.

Dr. Olsen was wonderful to work with. He got my dog in right away, diagnosed her problem, and the tooth extraction surgery went well! He personally spoke with me on the phone a few times to discuss her prognosis and was very reassuring. I so appreciate this clinic for treating my pet!

My pup had a likely to be harmful breast tumor growing, leading to taking her in to be evaluated. As it turned out it was cancerous and I was very thankful that she could be seen very quickly (within a week of her being seen the first time) to have the mass removed. The staff have all been very friendly and super accommodating- she can be dog reactive and they've let me into a private room, etc so she isn't being a pain in reception. She loved the staff and post op I was incredibly surprised to find her hanging out behind the desk with the receptionists watching her. Great staff and great service

I have been taking my cats here for 5 years now and will never go anywhere else. They are caring friendly and very professional. I had my two girl kittens spayed yesterday and the stitches are clean neatly done. My kitties are happy and recovering well thanks to the staff at Olsen veterinary clinic.

Absolutely loved the reception I received on a first visit. I felt the workers cared for my Big Kitty (Kit Kat) like I do. Thanks for everything!

They were able to get me in quickly when my previous vet could/would not. Dr. Olsen listened to my dogs history and made good suggestions to help work through his issues.

They were able to get my cat in the same day I called because of an infected leg. This was my first time there and I didn’t expect to be seen the same day but was happy that they could. I will definitely be using them for my vet.

I lost 2 cats in 2020 due to the financial hardship and expensive quotes provided by another well known very clinic in Glen Carbon. I was faced with another illness with my surviving cat this December and at a loss knowing I couldn't go back to our previous vet. I found Dr.Olsen on Google and they got me in the same day. They were able to treat and help my deathly ill cat and save his life without forcing me to make the choice of either giving him thousands of dollars or letting my cast die. I'm very grateful for him and his assistant, Andy! I only wish I would have known of him and his

We have been going here for well over a decade. Dr. Olsen has done a fine job taking care of our pets. He saved two of their lives. Sadly, they have all since died from old age, but we trust him with our new kitten.

Brought my dog here to get neutered and while the surgery was okay, the communication between the doctor, front desk staff, and me was horrific. The front desk staff was useless, including the doctor who never spoke to me after the surgery, and gave me little information about how to take care of my dog's post surgery needs or concerns. When I asked questions about post surgery, I was given a vague answer. BUT my FAVORITE answer I received when I asked the staff if my dog had glue or stitches was "I don't know. I wasn't there." I will not being going back and will tell

Jenna Kueper, who works here, is also involved with Four Paws Sake rescue group in Maryville, IL. These are not "rescuers", they are dog nappers. Just know that she is watching to see where pure breds are having litters so they can come confiscate your puppies and call you a "backyard breeder" when you try to get them back. Dr. Olsen might be great, but his staff is corrupt.

If I can sue this office for negligence I would.

This 'vet' hit my golden retrievers lower intestine during surgery, leading to an eventual death a week later. Absolutely unbelievable I am beyond broken for my angel.

NEVER TAKE YOUR PET HERE!!

If zero stars was an option I'd go with that...

I brought my cat in to see Dr. Olsen for the first time. He was diagnosed with a UTI (common in male cats). Dr. Olsen said that my cat needed to be catheterized and kept over night. He then called the following day to say that my cat was blocked up again so he re-catheterized my cat and kept him over the weekend. The doctor went out of town over this weekend, but decided to clear my cat to be sent home on Monday without seeing him first (which he admitted to). I went to pick my cat up after work on Monday and the
