Dr. Mondrian Contreras

Facebook Reviews:

We love CSAH! Dr. Contreras is our favorite. When my cat passed a couple of years ago and he was caring for him, he called to express his condolences. We are currently working on getting another one of our kitties healthy again, and he has been incredible. He is always so caring and informative. If you're looking for a great place to take your fur babies, this is the place! The rest of the staff is amazing, too!

Everyone at Carol Stream was super nice! My chinchilla has the best vet ever! She is super knowledgeable about the chins and addressed all of my concerns! Jack jack and I have found our vet and will be back in March to come for our annual checkup!

Animals are your family and when they are in pain, so are you. I visited Dr Contreras today for the 1st time and unfortunately it was not for a check up but a back injury to our little Moxie. The office staff and dr were fabulous! It's nice to see a dr do a very thorough exam, explain options and spend the time to not only care for your pet but make sure you are fully informed!

If you care about your other family members (sorry they are not just "pets" to me) this is the place to go. Depending on what needs to be done, it can be expensive, but if you weren't spending the money on your kids or your hubby, I can't think of a better way to keep my favorite companion healthy and happy for many years to come! Dr. John, Dr. Elise, Dr. Bhat and Dr. Contreras as well as the whole staff are welcoming, friendly, discuss options with you, call you before doing anything additional and will work with you if you are financially strapped. Not everything involves surgery and things can be done in a less invasive way depending on situation or pet's condition. I will forever miss Dr. Marty as he was so passionate about what he did and the patients he took care of too as they all touched him in special ways. God Bless you Marty - we all miss you terribly!

Dr. John Ciribassi and the amazing staff at CSAH are nothing short of perfect. My dog has gone here for every appointment from puppy vaccinations to routine checkups to microchipping (they even did her paperwork for us) to 2 ACL repairs to checkups during and after the therapy that followed. After each surgery, we were referred to different physical therapy facilities (because we moved) and I was pleasantly surprised to find Dr. John's business card at both locations. We commute from Chicago to Carol Stream because the level of care my pet receives, the friendly demeanor of the staff and the thorough answers to all of our questions, especially after major surgery, cannot possibly matched by any other veterinarian.

All the staff a CSAH are awesome, but we especially love Dr. John and Dr. Elise. They have been caring for our pets for the last 19 years, and they've seen us through good and bad. They are professional yet caring, technical and compassionate. We highly recommend CSAH to everyone who has a pet.

Yelp Reviews:

We LOVE the staff at this place! They are so good with both our dog and cat, treating them like their own fur babies. Their prices are reasonable and they take the time to explain everything and answer your questions.

Tracy Z.


Outstanding care for our dog. Even a phone consultation was informative, compassionate, and helpful. Truly top notch. If you care about your pet's medical care, don't hesitate to see them.

Peter S.


Dr. Contreras is am amazing veterinarian! He is competent, compassionate,
and genuinely listens to you and cares for your pets. He makes instructional videos, too. The other vets are really good, too, and the staff is friendly.

Anita A.


My husband and I LOVE this place. Our dog has some anxiety (she was neglected in her early months of life) and I swear Dr. Contreras is a dog whisperer. He makes her so comfortable the way he talks to her and handles her. He definitley found his calling in his love for animals. The WHOLE staff is so nice and accommodating as well. Shout out to Denise and Diane too!

Carol Stream Animal Hospital is an EXCELLENT facility all around.

I had a bad experience with an unnamed vet in the Aurora area, so I tried CSAH. Both Dr. Cirabassis (they are husband and wife) are excellent! They are kind, caring, and very gentle with my somewhat shy poodle mix rescue.

Their facilities are clean, and the staff is all very kind and personable. They are always friendly and answer my questions. Dr. Cirabassi even called to check on Harold the day after a procedure.

When I was traveling and needed to board my dog spur-of-the-moment, they faxed records immediately to the boarding facility.

When I moved to California, I was definitely sad to leave CSAH. Highly, highly recommended.
