About

Dr. Susan O’Brien followed her life-long aspirations of becoming a veterinarian.

She graduated from the Atlantic Veterinary College in 2010 with a Doctor of Veterinary Medicine degree. She is a 2006 graduate of Sweet Briar College in Virginia with a Bachelor of Science degree in Biology.

In her final year of veterinary school, Dr. O’Brien completed a rotation in a rural Peruvian village treating dogs, cats, donkeys and horses. It started a drive to continue philanthropic efforts and volunteerism throughout her career.

Following veterinary school, Dr. O’Brien completed a year-long extensive internship at a mixed animal practice in her native Ohio. She stayed on as an associate veterinarian at this practice for two years once she completed the internship in July of 2011. A lot of her focus during this time was general medicine and emergency care of horses, dogs and cats. She made the move to Colorado and began working at a small animal veterinary clinic while she developed her business.

Her inspiration behind Colorado On-Site Veterinary Services was to provide enhanced preventative care of dental maintenance, vaccination protocols, strategic deworming as well as nutritional guidance to maintain optimal health. She pursued several advanced certifications in the modalities of acupuncture, chiropractic care and laser therapy in order to offer a full array of services to her patients. Dr. O’Brien is certified in veterinary acupuncture by Medical Acupuncture for Veterinarians. She is certified in chiropractic care by the International Veterinary Chiropractic Association and the Options for Animals College of Veterinary Chiropractic.
