How Gregg works

Every engagement is personal. Gregg gets to know each client’s finances, family, and business, and that knowledge carries forward from one year to the next.

Directly with you

You speak with Gregg from the first conversation onward. He knows your history, your goals, and the details behind every number on your return.

All year long

Tax season runs all year in this practice. Questions about a sale, a new business, a notice, or a life change get answered when they come up.

Planning first

Good planning makes filing straightforward. Gregg looks ahead with each client, so April confirms a plan already in place.


“Gregg is an excellent accountant. He works very closely with you to ensure everything is considered. Gregg always returns calls and emails promptly, and you are not kept waiting. Gregg offers a very professional and personal service that you will not find with franchise accounting services or the software accounting that is available. I would highly and strongly recommend Gregg to those in search of an accountant.”
