Tom Speroni

Executive VP / Principal
Tom studied Real Estate and Construction Management at the University of Denver, where he also earned a degree in Business.

Later, bringing this strategy into the healthcare sector, he successfully applied a similar approach to dialysis centers, Lasik eye surgery clinics, and dental offices.
