We are fortunate to have a team of dedicated, caring people as your pet's healthcare team. Each and every one has been called to this profession by a deep respect and love for animals. We look forward to getting to know you!
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 two dogs, Calvin and Blue. Dr. Atlas enjoys skiing, running, golfing and playing soccer.
Don Kammerzell, DVM
Dr. Don Kammerzell is a Colorado native, born in Denver and raised in Wheat Ridge, Colorado. He graduated in 1983 from the University of Colorado in Boulder, with a BS in Business, with honors. He then graduated in 1989 from Colorado State University receiving his DVM degree again with honors. For 9 years Dr. Kammerzell worked as a mixed animal practitioner treating cattle, horses and companion animals in both Limon and then Fort Morgan, Colorado. In 1998 he moved to Littleton and has been treating only companion animals since. As of 2003, he has specialized in companion animal relief practice, filling in as a substitute for veterinarians and their practices in the greater Metro Denver area.
He lives in Littleton with his wife, Debbie, and their two dogs Rascal and Anna. Dr. K, as he prefers to be called, enjoys spending time in the great outdoors with his family and cruising with his wife on his motorcycle. He currently works every Thursday and every other Saturday, for Beaver Brook Pet Center, to allow Dr. Atlas some deserved time off.

Veterinary Technician Team
Lance Bradbury, Certified Veterinary Technician (head technician)
Lance is a Denver native and grew up in Littleton. He started college in Utah, at Brigham Young University, but was a more serious skier than student. He came back home and worked in the Hotel and Restaurant industry for 6 years before finding his niche in the Veterinary field. He graduated from the Bel-Rea Institute in 1990 and then Metropolitan State College in 1993 with a B.S. in Zoology. Lance worked in Littleton as a CVT for 23 years where he met and worked with Dr. Atlas, Kevin, and Susan. The opportunity came to work in Evergreen at Beaver Brook Pet Center in July of 2013 and he made the move up the hill. Lance plays competitive Beach Volleyball year round and depending on the season, he loves to hike, bike, snowshoe, and ski.

Client Care Team
Elizabeth Campbell, Client Care Specialist
Born and raised in Georgia, Elizabeth felt the draw of the west! Attending both CSU and University of Utah, she graduated with advanced degrees in Geology. She worked in the Oil and Gas industry for many years during which time she and her husband, Bob, moved to Texas and then Canada. After moving back to Evergreen, she took time off from work to raise a family (both 2 -legged and 4-legged!). She is thrilled to be a part of the wonderful team at Beaver Brook.
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 the fast-past media environment, 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!
