Susan O'Brien


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.

In her free time, you’ll find her riding, hiking, fishing and enjoying the great state of Colorado with her husband Kenny and daughter Violet. They share their home with three dogs, two cats, a haflinger and two quarter horses and a host of ducks and chickens.

Original Clinic Cat

Gayle was our 18-year-old clinic cat.

She was the original clinic cat at On-Site Veterinary.  She was adopted from a local shelter as a senior cat and lived her best life at the clinic.  She was diagnosed with kidney disease while in our care.  The disease quickly progressed and we made the painful decision to let her cross the rainbow bridge.  May Gayle rest in peace and may her legacy live on!

Previous Clinic Cat

Bueller was our 8-year-old clinic cat.

He was adopted from a local humane society in April of 2023.  Shy and reserved, he was unsure about being in a new setting after all the recent changes in his life.  On his initial exam, we noted that he had significant dental disease.  We performed a dental cleaning and extracted 9 teeth.  After 2 weeks of healing, he was a completely different cat!  He is the most talkative, playful, and happy cat.  He spent almost 7 months as our clinic cat until Dr. O'Brien decided that she loved him so much, she needed to take him home.  He is now living his best life with Dr. O'Brien family!
