Dr. Gwendolyn Steffen, DVM

Raised in rural Campbell County, Dr. Gwendolyn Steffen received her B.S. from Northern Kentucky University before studying abroad to receive her D.V.M. from Ross University School of Veterinary Medicine on the island of St. Christopher and Nevis. Dr. Steffen has never known life without an ever-present menagerie of animals to enrich her experiences.

From within her own tri-state, to Oklahoma, St. Kitts, Newfoundland, Greece, and Asia, Dr. Steffen has interacted globally with people who love animals so she may better understand the depths of the relationships and the cultural values held in areas way beyond the scope of her textbook and clinical training. As the sole owner of Companion Animal Medical Centre, Dr. Steffen now incorporates several holistic modalities that envelop the more traditional methods of practicing veterinary medicine.

Giving Back

Dr. Steffen also gives of her time and energy to move beyond the walls of her veterinary practice. She has provided relief work to veterinary clinics/hospitals in various locations, along with donating her time and skills to help animal shelters and other organizations in the tri-state area with spays and neuters. She has established and facilitates a lucrative fund-raising event, The Blu Cat Benefit, annually since 2009 to benefit local no-kill, non-profit animal rescues.

Dr. Steffen is also a partner with Luv Fur MuttsClermont to the Rescue, and Sacred Hearts Animal Sanctuary which are all a 501c3 non-profit no-kill animal rescues in the tri-state.

Holistic Modalities

Dr. Steffen is a level II Reiki therapist and is the only veterinarian in the United States certified in Chiro + Kinesiology. She is trained in dōTERRA and Young Living essential oils, Standard Process, Thorne Research, and Vet Classics along with other nutraceutical product lines. She also has over 100 hours of continuing education in cannabinoid therapy and nutritional diets for companion animals suffering from cancer.

Past and Continuing Experience

Dr. Steffen was the Recording Secretary on The Cincinnati Veterinary Medical Association’s Board of Directors for three years and a member of Business Network International for one year.

Dr. Steffen was appointed to the WAVE Foundation Board of Directors in the fall of 2013 and recently resigned from the organization after holding the following positions: Executive Secretary (2 years), Trustee (2 years), Chair for the Resource and Development Committee (3 years), Co-Chair on the Nauti Nite Committee (2 years), Committee Member (3 years), and on the David Fulcher’s Putt For Penguins Committee (3 years).

Companion Animal Medical Centre Affiliations

Dr. Steffen is an active member in the following veterinary associations:

American Holistic Veterinary Medical Association Logo
  • Having your female cat or dog spayed reduces their risk of developing breast tumors, which are malignant or cancerous in 50% of dogs and 90% of cats. 
  • Neutering your male cat prevents unwanted behavior such as urine marking, roaming, fighting, and aggression.
  • Pets are much safer when they're at home. Spaying or neutering helps prevent roaming behavior, making it far more likely your pets  will stick close to home and be easier to locate in the unfortunate event they're lost.
  • Kittens as young as 8 weeks old can be safely neutered or spayed, completely preventing your female cat from ever going into heat or your male cat from urine spraying.
  • Having your pet spayed or neutered is much more cost effective than taking care of an unexpected litter of kittens.
  • The number of both cats and dogs euthanized each year has been decreasing in part to spay and neuter campaigns. We'd love to see this continue!
  • Your pets will be as sleek as ever! The idea that having your pet spayed or neutered will make them overweight is a myth.
