While doing this he was hands-on in nearly every aspect of the business which went beyond just the accounting into licensing, human resources, inventory management, practice relations, insurance, and much more. During his tenure in the healthcare industry he has helped each entrepreneurial company that he has worked for grow and eventually be sold to private equity.
