Serving Las Vegas and Henderson, NV for Over 25 Years—Welcome to Park Animal Hospital

Park Animal Hospital opened in 1991, and we have operated under one premise: We want to see the same clients 20 years from now that we are seeing today!

We strive to provide the warmest and most knowledgeable customer service, the highest quality assistance, and state-of-the-art patient care through preventative medicine, and diagnostic and surgical procedures.

Park Animal Hospital also takes an active role in our community by working closely with many nonprofit organizations and we always have our own rescue projects going. You can see many pictures of our successful rescue projects in the Photo Gallery. We promote pet population control and adoption where possible and many of our staff are proud owners of rescue pets, which include but are by no means limited to dogs, cats, reptiles, rabbits, rats, horses, and numerous birds.

With so many years’ experience, Dr. C likes to share his knowledge by encouraging others in the veterinary field. He often hosts interns and continuing educational programs for the staff. With the highest level of standards and quality of medicine, Dr. C aides others to be able to achieve their dreams of helping pets and wildlife.

We recognize that your pets are not just animals; they are part of your family and as your family’s doctor, we will do our best to make both you and your pet feel welcome and comfortable.

We want your family to be our family too!

She found Atlas as a starving street dog while in vet school and vowed to find him a home- turns out the home was hers. Not long after joining us at Park, a homeless ferret (now named Harvey) came in for being sick and he weaseled his way into her home as well.

When she is not caring for pets, Dr. Graben enjoys wheel thrown pottery, painting, photography, anything with glitter, hiking, and traveling.
