Grant Davis, Founder / Agent

Grant Davis, Founder / Agent

Founder/Agent

Grant was born and raised in the San Francisco Bay Area where he met the love of his life, his wife Minnette, and graduated from San Mateo High School. After serving in the United Sates Army, Grant Davis began his career selling insurance door-to-door as a one-man agency in 1980. By 1985 he joined and became partner in a small independent agency until 1987 when it was acquired by a larger firm. In 1989 he decided to start his own agency, the predecessor to GDI Insurance Agency, Inc. (GDI), as an exclusive agency. Frustrated with being hindered by the lack of products provided by exclusive carriers for his clients, Grant decided to leave the exclusive arena and start a scratch independent agency in 1999. GDI has since grown to do business across the country and is ranked as one of the largest and most innovative agencies in its primary markets.

Grant has always taken it upon himself to create and/or improve upon the products and services in the marketplace to ensure his clients are provided with the best programs to meet their needs. Noticing the impending burst of the housing bubble, he created the Home Value Plus program in 2007 to cover 20% of the market value of a home. More recently, he created Credit Enhancement Bonding and Insurance as a program to secure his clients’ Businesses and Projects in order to increase the likelihood of acquiring funding. In addition to receiving acclaim for the programs listed, he has also been featured and published numerous times in trade publications such as Rough Notes, Agent & Broker, Builder & Developer, Personal Real Estate Investor, and many others.

Grant is a nationally recognized thought leader on the topic of insurance sales, and has personally contributed to the success of multiple multi-billion-dollar commercial developments throughout the United States.

Grant resides in Turlock, CA with his wife Minnette. They have four adult children and seven grandchildren. They enjoy spending time together and travelling back and forth to Texas to visit their children and grandchildren.

Bill Waite

Bill Waite

Account Executive, Tulare

Bill Waite literally stumbled upon GDI Insurance in mid-March, 2012.  After attending a webinar that featured a nationally recognized insurance industry consultant, he began to investigate the consultant’s track record by examining the testimonials featured in the consultant’s marketing materials and website.  One company in particular stood out from all the others to him.

Since this company happened to be located just a couple hours away from Bill’s office in Tulare, he decided to contact the founder of this company, Grant Davis – not for a job but rather for encouragement.  You see, after several years as an independent insurance broker, Bill knew the level of service he wanted to give his clients and he knew that as a one-person office he couldn’t meet his own expectations in that regard.  Grant offered many thoughtful insights and the two agreed to sit down and talk further.  In GDI Insurance, Bill found all the resources and expertise needed to deliver the kind of client service that he always knew just had to be available somewhere.  Bill quickly came to realize that GDI didn’t simply deal in insurance but rather in solutions.

Bill has always been a problem solver – in recent years as an insurance broker and in over twenty-five years before that as a business consultant and in various other capacities structuring and placing diverse commercial loans and other asset-backed financing and leases for both U.S. and Mexican businesses.  Some of his transactions completed include restaurant fixtures financings, a cross-border point-to-point satellite communication system and a $24.5 million sale-and-leaseback (via bareboat charter agreements) of two ocean-going cargo vessels.

Bill is a 2002 graduate of Point Loma Nazarene University (Bachelor of Arts in Business Administration with an International Emphasis and a minor concentration in Spanish).  Bill is a husband, dad and “Grampa” and also enjoys his involvement with the Tulare Sunrise Rotary Club.
