WellHaven COVID-19 Updates

Your Full-Service Denver Veterinarian

WellHaven on Park Ave.


Full-Service Veterinary Hospital in Denver

If your dog is acting down in the dumps or your cat just isn’t as curious as they usually are, your Park Avenue WellHaven is here for you and your pet. It can be a stressful time when your four-legged family member isn’t feeling their best and you just aren’t sure what to do. As pet owners ourselves, we know how important pets are for a happy home.

We do our best to get your pet back to their old selves through annual examinations, monthly treatments, and other scheduled visits. Our Fear Free exam rooms and welcoming lobbies are designed to make our patients (and their parents) as comfortable as possible while we provide unsurpassed care.

I’ve been taking both my dogs there for a while. I really like how fast I can get an appointment and they do a good job calming me down every time I freak out about a mark on one of my dogs. One of my pups is a lot to handle (doesn’t like other dogs, doesn’t like people making eye contact, etc…) and they do a great job working around her difficulties.

This team has been so so helpful and loving to my Trapper. We’ve been coming here for a few years now and I have nothing but great things to say. Thank you all!

The WellHaven Difference

Our clinics are designed to give you pets the best possible care while ensuring our doctors, nurse technicians, and the rest of the staff have the support and resources they need to provide that care. By allowing our doctors to focus on their patients, providing state-of-the-art technology, and ensuring a healthy work/life balance, they are better equipped to care for your pet.

We promote healthy collaboration among all staff members and offer continuing education for those that want it. We feel this creates an environment where our caregivers truly feel supported. And it shows in the level of care they provide your pet. It’s not just a slogan: We truly believe in “Happy Vets, Happy Pets.”

Denver Vet Services

WellHaven offers a full slate of preventive, dental, and overhaul pet health care at its Park Avenue location in Denver. It all begins with our initial examination when you first get your pet. No matter if it’s an older rehomed dog or a new kitten, this first appointment will let us set a healthcare baseline that we can use throughout their lifespan.

We also provide necessary vaccinations, regularly scheduled parasite treatments, and dental care for your pets. Our hospitals are equipped with radiology and internal medicine equipment, an in-house lab, and on site pharmacy so we can quickly test, diagnose, and treat most issues. If your pet has had an accident, please call ahead so we can recommend a course of action.

AAHA Accredited

WellHaven takes great pride in having our hospitals meet the criteria of accreditation set by the American Animal Hospital Association. With nearly 900 checks and standards to meet, the AAHA sets the bar very high for veterinary hospitals and the animal health care industry as a whole. We want all of our locations to meet, if not exceed, those standards.

To our loyal clients,  

To provide you and your pets with the best possible care, we have made the decision to merge our WellHaven Park Ave. Location with our South Colorado Blvd. location. All our staff from this closed location is moved over to our South Colorado Blvd. location. They are located a short drive away from WellHaven Park Ave., along South Colorado Blvd and I-25.  

Our South Colorado Blvd. hospital is equipped with new state-of-the-art equipment to service your pets. We understand that you have come to love and support the team at WellHaven Park Ave; we are excited to announce that the Park Ave. team will be moving to our South Colorado Blvd. location. Although we are merging these locations, we believe that you will experience the same passion and professionalism you have come to experience at WellHaven Park Ave. We encourage you to check out the hospital's website or social media platforms listed below to gain a better understanding of the hospital and the team! 

We appreciate your loyalty as a client and for those of you who choose to continue services with WellHaven at our South Colorado Blvd. location, we would like to offer you a discount on your next visit. 

Thank you for your support and we look forward to scheduling you soon.
