After a two-year interruption, MASH – Main Street Animal Services of Hopkinton is back to doing what it was created to do: helping animals heal and supporting the people that love them. Having returned to practice since last November after the state veterinary board voted to reinstate her veterinary license has reinforced why owner Margo Roman, DVM, CVA, COT, CPT, FAAO, became a veterinarian nearly five decades ago—and why the Veterinary Oath still matters to her.

The Veterinary Oath commits doctors to use their scientific knowledge and skills to protect animal health and welfare, relieve suffering, advance medical knowledge, and practice with dignity, ethics and lifelong learning. That oath has guided her work for 48 years. It’s not a ceremonial statement; it’s a living commitment that shapes clinical decisions every day.

“Science, however, doesn’t belong exclusively to universities, pharmaceutical companies or institutions,” says Roman. “True scientific progress comes from observation, inquiry, outcomes and the willingness to learn from patients themselves. Over the last two years, I authored two comprehensive textbooks reflecting that philosophy: one on veterinary medical ozone therapy [A Practical Guide to Veterinary Medical Ozone Therapy co-authored with Dr. Jyl Rubin] and another on the microbiome and MicroBiome Restorative Therapy (MBRT), an approach that supports the immune system and gut ecology as a whole. Many of the cases described in these books changed how we understand healing—not because they followed convention, but because they followed results.

“Today, I continue to teach and share this work through RACE-approved courses [part of the American Association of Veterinary State Boards’ Registry of Approved Continuing Education program], national conferences and the AVMA Annual Convention in 2026. Knowledge shared responsibly strengthens a profession; it does not threaten it.

“Every healing profession should be motivated by the same question: How do we best support the body’s innate ability to heal? For me, the answer remains grounded in science, ethics and the oath I will always honor.”

As a full-service integrative veterinary clinic, MASH provides a variety of treatments and services including acupuncture, functional nutrition, homeopathy, chiropractic, herbs, ozone therapy, surgery and dentistry.
