Dr. Albert Chai and Dr. Jasmine Tom are the founding veterinarians of Blue Spruce Animal Clinic. Both doctors graduated from the prestigious veterinary medicine program at Colorado State University.

Dr. Chai is a native of Austin, Texas and grew up with a passion for all animals. At a young age he knew he wanted to help animals as a veterinarian. Before opening Blue Spruce Animal Clinic, he had the unique opportunity to intern with zoo and exotic animal veterinarians in Tucson, AZ.

Dr. Tom is a native of Honolulu, HI and spent large parts of her youth volunteering at animal shelters and clinics. In addition to general practice, Dr. Tom discovered a passion for emergency medicine years ago as an intern at Animal Hospital Specialty Center in Highlands Ranch.

She met Dr. Chai during their freshman year of college, and found somebody who shared her passion for animals. They both remain ever grateful to Colorado State University and the great state of Colorado for bringing them together.

When not in the clinic, Dr. Chai and Dr. Tom, along with their dog, Tucker, can be found hiking Colorado's mountain peaks and alpine lakes in the summer, and skiing fresh powder or snowshoeing the backcountry in the winter.
