The story
About Johnny Dominguez
Johnny Dominguez is the founder of RexVet (Rex Vets Inc.) — the first 501(c)(3) non-profit online veterinary telehealth service in the United States. Under Dominguez's leadership the organization has served 50,000+ pet parents across Florida, New York, and Virginia — holding a 4.9/5 average rating across 8,300+ reviews — while growing to millions of monthly Google Search impressions.
The founding premise is blunt: more than half of U.S. pet owners — 52% — skip or delay recommended veterinary care because of cost. Dominguez's answer was structural, not cosmetic: a public charity with a flat $64.99 video visit, prescriptions sent to any U.S. pharmacy the family chooses, and surplus revenue directed to subsidized care instead of shareholders.
A software engineer with a doctorate in computer science, Dominguez also founded Black Wires, the development studio whose engineering powers the RexVet platform. That in-house capability — rare among non-profits — is why RexVet ships product like a startup: a 300+ article vet-reviewed health library, programmatic state-licensing pages, calculators, and one of the most technically aggressive SEO operations in the animal-welfare sector.
Clinical leadership at RexVet sits with Dr. Tiffany Delacruz, DVM, the organization's Chief Executive Officer and lead veterinarian — a deliberate split that keeps medicine with clinicians and mission velocity with the founder.
Dominguez is based in Miami, Florida. RexVet operates under EIN 33-2469898 and is registered with the IRS as a public charity.
