Susan O'Brien, DVM

Dr. Susan O’Brien followed her life-long aspirations of becoming a veterinarian when 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 three dogs, two cats, a haflinger and two quarter horses and a host of ducks and chickens.

Liz Neill

My name is Elizabeth and I hail from the sunshine state, Florida. I spent my school holidays in Eagle County visiting family for most of my childhood and absolutely LOVE the snow. I worked in the Bahama’s for three years before moving to the Rocky Mountains and I have a degree in Zoo Animal Technology. I am continuing my education through Colorado Mountain College and will be graduating from their veterinary technician program in May. I love photography, especially nature/wildlife and couldn’t ask for better scenery; summer, winter, spring and fall. I love the valley and am so happy that I finally get to call it home.

I am new to the Colorado On-Site Vet team but not new to the valley. My husband and I were both born and raised here as well as our four children. We have no intention of leaving anytime soon. We are a very busy family; living in nature’s playground it’s hard to not be doing something. We all love golf; here it’s easy to play nine months out of the year. Skiing and riding are our second favorite thing; the kids and dad love the trees, while mom likes taking it slow. We have two pound puppies; they’ll be eleven soon. Our hikes our getting shorter as the recovery time for them keeps getting longer and longer but, they still love camping and swimming in any lake or stream they come across. Anyway, I’m happy to be a part of team with so much care and compassion in everything they do, and I can’t wait to see what the future holds.
