Linda Contos, DVM, MPH


Special interests are: BIRDS, (Avian Medicine), THERAPY DOGS, SERVICE DOGS, AGILITY dog training, and international travel.

She has a THERAPY DOG, “Kronk”, and as a therapy dog team they go to schools, nursing homes and hospitals.

She has been practicing in New Mexico since 1989. After graduating from Ross University School of Veterinary Medicine, she worked in an avian specialty clinic, where she advanced her knowledge of birds. So in addition to working with dogs and cats, she has a special interest in exotic animals such as birds, ferrets, reptiles, rodents and llamas.

While her son was young, she worked at the University of New Mexico part time as their Laboratory Animal Veterinarian, and received a Masters Degree in Public Health. More recently she has taught veterinary technician classes at the CNM Veterinary Technology Program. Her home is populated with 5 llamas, 3 dogs, 3 birds, a husband and son.

John Heidrich, PhD, DVM


He recently spent a year in Cambodia teaching veterinarians and technicians so that they can improve their medical skills.

His passion is to find the best care for all animals through educating students.

He has strong surgical interest in orthopedics and the treatment of chronic pain. Besides his interest in pain management of your pet, he has been involved with studies of how diseases can be transmitted between animals and people as well as from people to animals.

He has spent his working vacations over the past 15 years trapping wild cynomologous monkeys in Nepal, Bangladesh, Thailand, Indonesia, and Cambodia.

Because of his international interests he has spearheaded the WORLDWIDE PEN PALS program, linking Albuquerque area schools with those abroad, in encouraging literacy and writing and international awareness in school children. Countries involved in this pen pal program are Cambodia, Guatemala, Tanzania, Malawi, Papua New Guinea and more to come.

Dr. Heidrich was instrumental in the start up of the veterinary technician program at CNM and loves having students in the clinic. We want to share with students our lifelong commitment of providing the best care, as a member of your health care team for your pet.
