  • Our vision at Tiresias Consulting LLC is to transform lives by bringing novel therapeutics to human and animal patients.
  • Our business is named for Tiresias (ty-REE-see-uhs) the greyhound, who lived with Jay and his family from 2014 to 2021. He was a professional racer and was forced to retire early due to serious illness. Tiresias saw an army of veterinarians during his life and took myriad drugs. Throughout his medical odyssey, he maintained a gentle spirit and contagious joy for life that touched everyone he met.
  • The namesake of our greyhound mascot is Tiresias the blind prophet of Thebes, a character from Greek mythology. The ancient Tiresias appears in several tales, including the Odyssey, and has the gift of foresight. Tiresias was famously transformed by the gods from male to female (and eventually back again) as a punishment for striking two intertwined snakes with his staff. These mythological serpents are featured in the logo for Tiresias Consulting LLC.
