Michael Greener, DVM

University of Illinois

Dr. Michael Greener grew up on Long Island, NY, where his passion for animals began early—he started volunteering at his local public animal shelter at just 12 years old. Inspired by this experience, he knew from a young age that he was destined to become a veterinarian.

He earned his bachelor’s degree in Environmental Biology from the State University of New York College of Environmental Science and Forestry (SUNY-ESF) in Syracuse, NY. He then attended the University of Illinois College of Veterinary Medicine in Urbana-Champaign. 

Since 2022, Dr. Greener has been practicing in the Bay Area, working both as a full-time general practitioner and a relief (locum) veterinarian. In 2025, he took dedicated time to deepen his knowledge in dermatology, an area of special interest.

Dr. Greener is committed to building strong, lasting relationships with both his clients and their pets. He focuses on creating a calm, low-stress environment during every visit to ensure the best possible experience for his patients.

A lifelong animal lover, Dr. Greener brings compassion, expertise, and dedication to every aspect of his work.

  Russell Nichols, DVM

University of North Carolina

Dr. Russell Nichols pursued a career in veterinary medicine after rediscovering a passion for animal behavior during graduate studies in the social sciences at the University of North Carolina.  Previously, while at UCSD, he had done fieldwork with migratory juncos and volunteered with harbor seals during pupping season, and after deciding to become a veterinarian, he worked in a laboratory with spadefoot toads, at a small animal clinic, and conducted behavioral research with peafowl at Duke University.  Once in veterinary school at North Carolina State University, Dr. Nichols specialized in comparative medicine and, after graduation, completed a residency in this specialty at the University of Michigan.  Seeking to address Global Health challenges through both research and companion animal medicine, Dr. Nichols has worked with a large variety of species, but believes that supporting the human-animal bond through companion animal health is of critical importance.  Dr. Nichols is dedicated to thorough, compassionate animal care, and to finding solutions that give pets the healthiest, happiest lives.
