About this Advisor

Mario Hernandez is a partner at Gemmer Asset Management, LLC, a California-based firm with more than $980 million in asset under management (AUM). Hernandez has been with the firm for 22 years and has been in the financial planning and investment management business for 25 years. He currently serves as the financial planner for in-house clients, and he also heads up the the firm’s wealth management division.

A certified financial planner (CFP), Hernandez provides holistic planning for clients and specializes in helping them prepare for retirement. In addition to retirement planning, Hernandez also provides investment management and Social Security planning. He also has an insurance license through the State of California. He has a bachelor’s degree in accounting and finance from Cal State University, Hayward and a master’s degree in financial planning from Golden Gate University.

Hernandez works with investors in the San Francisco Bay area. He specializes in serving high-net-worth-individuals and business owners, and he requires an account minimum of $100,000. A fee-only advisor, Hernandez charges his clients a 1% flat fee per year. However, depending on a client’s asset level, Hernandez may reduce this percentage as clients’ asset levels increase.

The most common mistake that Hernandez sees investors make is not putting enough away for retirement. Hernandez says that his firm takes a holistic approach to finding solutions for a client’s financial situation, considering both the financial and non-financial goals that a client wants to accomplish. In addition, Hernandez says his firm works with outside tax and estate planning experts and insurance and mortgage specialists to help come up with a plan that makes sense for the client. He says the firm manages risk in clients’ portfolios through diversified asset allocation strategies that focus on providing attractive returns with less volatility than the equity markets.

Outside of the office, Hernandez coaches a high school soccer team at Las Lomas High School.
