Jeff Maas received his real estate license in 1988 and Broker's License 2 years later. In 1991, after being a Top 5 agent at Century 21 for 3 years and earning his B.S. in Finance, Real Estate and Law from Cal Poly, Pomona, Jeff founded National Realty Group. Three years later he realized that only offering real estate services was short-changing his clients.

With a partner, Maas purchased a mortgage company that would become National One Mortgage Corp. National One Mortgage had 5 agents and employees at that time. Jeff later bought out the partner to become sole owner. A few years later that number the company had over 300 agents in 9 locations. It became the largest One-Stop for all your Real Estate needs office in California.

In 2001, Escrow One was added to provide escrow services. A year later, America's Best Property Management was added to provide management services to the investor clients.

Jeff Maas continues to personally provide real estate and loan services to his clients. Nearly 100% of his business comes from referrals, showing the experience and care he provides everyone he helps.
