Created by a Physician for Clinicians

Lecat’s Ventriloscope® LLC was established in 2008 by Dr. Paul and Fran Lecat. The Lecat’s founded the company on the principle that physical examination, when performed correctly, can reduce mortality through earliest recognition of deadly conditions. Frustrated by the inability to incorporate realistic abnormal sounds in teaching, Dr. Lecat invented and patented the technology behind the Ventriloscope®.

Dr. Lecat works at NEOMED’s College of Medicine, where is he a Professor of Internal Medicine, Pediatrics, and Family and Community Medicine. He has practiced Internal Medicine and Pediatrics at Cleveland Clinic Akron General.

Dr. Lecat earned a Bachelor’s of Science in Biology at Tulane University, where he was recognized with honors. He was also named Salutatorian in the Doctor of Medicine Program at the University at Buffalo (SUNY).
