Michael Lebner
Founder & Director

Michael Lebner is the developer of Clozex technology, the founder of Clozex, and resides on the Board of Directors. Michael has held senior management positions in various industries in addition to consulting with a national CPA firm for 7 years.

Michael’s idea for an improved skin closure stemmed from family accidents in which he felt the suture closures that were used seemed overly crude. His Clozex idea attracted the immediate interest of surgeons, patent attorneys and manufacturers who joined Michael in developing the original patents, gaining FDA approval and building and testing sample products. Clozex’s early years of development are still studied at the Harvard Business School. More recently, Lebner has led the positioning of Clozex product for mass distribution, which has included high speed manufacturing, building the patent portfolio and demonstrating its adoption in New England hospitals.

Michael has a Bachelor of Science in mathematics from McGill University and a Masters of Business Administration (MBA) from the MIT Sloan School of Management.
