Barbara Lamar

Barbara Lamar has provided legal and accounting support to small businesses and their owners for more than 26 years. One of her primary goals is to make sure that fees paid to our firm will be a profitable investment for our clients – for every dollar paid in fees to our firm, the client should gain more than a dollar in taxes saved and/or increased business profits.

When she is not being an accounting and legal geek, Ms. Lamar works on her Permaculture farm in Caldwell County, Texas.
