    Dr. Dan Atlas, DVM

    Dr. Dan Atlas grew up in New York and obtained his Bachelor degree in Animal Science in 1998 and his Doctorate of Veterinary Medicine in 2004 from Cornell University. He began his career in a busy small animal practice in southern New Hampshire, but was easily lured to his wife's home state of Colorado (as many of us are) for the beautiful landscape and endless outdoor activities and amenities.

    Prior to purchasing Beaver Brook Pet Center from Dr. Manobla in 2012, Dr. Atlas practiced primarily in southwest Denver, including serving four years as the medical director at VCA Dakota Ridge Animal Hospital. Dr. Atlas is a member of the American Veterinary Medical Association, the Colorado Veterinary Medical Association and the Denver Area Veterinary Medical Society (DAVMS). He has a special interest in preventative care and geriatric medicine, but enjoys all aspects of general practice, including soft tissue surgery and dentistry.

    Dr. Atlas lives in Evergreen with his wife and two daughters as well as their two cats and dogs, Blue and Hobbes. Dr. Atlas enjoys skiing, running, golfing and playing soccer.

Client Care Team

  • Sherri
    Sherri Velte
    Client Care Specialist

    Sherri grew up in the suburbs of Motown, always with a pet at her side. During that time, her family took many road trips to Colorado, where like many, she fell in love with the Rocky Mountains. It became a dream to live in them one day!  After serving decades in a fast-paced TV production and design career, she followed her heart by moving to a more community-based and pet-oriented career closer to home in the mountains. She enjoys combining her past customer-service experience with her life-long love of animals!

    She and her husband have raised their two children and eight family dogs here in Evergreen. They currently have a redbone coonhound and a funny little rescue-mix that always keeps them smiling.  Sherri says she is blessed to be able to “work” at Beaver Brook Pet Center, where her family has been taking their own pets for over twenty years!
