After graduating from Pennsylvania State University, Lou got his start in finance working first for the former ‘Big 8’ firm Price Waterhouse & Co. in Manhattan, and then as a money manager at First Interstate Bank in Los Angeles. As a Founding Partner, Lou launched the financial consulting firm known since 1999 as Gatto McFerson, a CPA and Finance Firm that specializes in the Veterinary Industry. During his 40 years as a Veterinary Practice Management Consultant and owner, he has helped veterinarians accomplish their personal and professional goals.

Lou and his wife Kathy care for more than 80 of their own pets (cats, dogs and exotic birds to name a few). The animals bring such joy, and they consider themselves fortunate to connect with Mother Nature in this way. When not in the office, Lou & Kathy explore the world by boat, fish, golf, are Dodgers fans, and enjoy playing with their grandkids.
