About G Griggs CPA

Top quality accounting services for your business 

G Griggs, CPA Inc. was born from the founder’s desire to provide top-notch services to people looking for a long-term relationship with their CPA. Our goal is to be much more than tax preparers, rather trusted professionals working with our clients toward a single goal. We never want to grow to the point that our clients find us too busy to be accessible to them.
