Louis M. Gatto, CPA — Founding Partner

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. He calls his clients truly great people from whom he has learned a lot over the years, and he feels privileged to have served a few for over 30 years. Lou takes pride in knowing that Gatto McFerson has helped so many veterinarians accomplish their personal and professional goals. When not in the office, you can usually find Lou fishing, playing with his grandkids, on the golf course, watching the Dodgers, or caring for one of his 80+ pets.

She finds her co-workers fabulous to work with and feels good knowing she is a contributing member of the team. A fan of the outdoors, Julie enjoys hiking, boogie boarding and playing with her English Bulldog puppy, Rockie, and her mixed breed, Louey.

Sylvia joined our team in 2012 with over 20 years of experience as a legal assistant/paralegal with an emphasis in real estate and corporate matters. She was hired primarily to support founder, Louis Gatto, and has quickly adapted to becoming his right-hand person as well as assumed various other responsibilities. Sylvia enjoys client interaction the most and is eager to learn the consulting end of the business as well as the tax services we offer our clients. She is planning on obtaining certification in Quickbooks and has begun taking financial courses for non-accountants so that she can contribute more to the team.
