We recently moved to town, and have been looking for a good place to take our poodles, and we found it! The staff was so friendly, and Dr. Harres was wonderful with our 2 miniature poodles. Dr. Harres answered all of my questions, and was very helpful.

I can’t possible say enough, about the greatest Veterinarian around, Dr. Mike Harres. I am so grateful to have met him on a baseball field, and ask him if he would take care of my dogs, I had 7. Very soon, I will be down to 2, as one more has reached that point in life to go to a better place. And Dr. Mike will do the duty. He is the most comforting, patient, courteous, wonderful Vet that I have ever met, and I had several. Thank You Dr. Mike and your staff, for your wonderful care of all my dogs. God Bless You

I trust Mike & his staff so much that I drove 18hrs back from near Orlando Florida where I had been visiting friends to have him take care of Daisy & Suzie my 2 dogs & have him do their surgery. I’ve been seeing Mike for my (our) dogs since 1979 when he was in the old bank down the street. There are many stories I can tell, like the day we picked up the wife’s poodle Mindy who had broken her leg. Mike told us “I hope you’re not mad at what I did”. When asked what it was he told us he was in the office on a Sunday & Mindy looked lonely so he took her for a ride when he did his errands. Both Denise & I laughed about it & told Mike that Mindy would forever be his buddy for doing that. The wife & I considered Mike more then just our Vet, we consider him a good friend because of all the years of taking care of our dogs & the relationship that has grown over the years.

Everyone there is so professional from the office staff, vet techs and vets. They are very caring and the doctor herself called with lab results for our cat. Highly recommend Mon-Clair!

After leaving our old vet with a bad taste in our mouth, I spent an hour reading reviews on vets in my area. I picked this practice and couldn’t be happier. Dr. Meyer was kind, thorough and knowledgeable. I especially liked the fact that she got me involved in how to treat my dogs ear infection to ensure it would be properly taken care of once we were home and on our own. I can now relax knowing that my fur babies will be taken care of at a quality I have always felt they deserve.

Dr. Harres has treated our dogs like family for somewhere around 20 years now and I wouldn’t dream of taking them to any of veterinarian office.
