Our History
Family Ties
The story of Trusted Accounting Partners goes back long before the business was founded. In fact, our story begins in 1961, when our fathers met and became best friends—building a bond that’s lasted more than six decades. They grew up together, supported each other through life’s milestones, and passed on the same values of integrity, hard work, and loyalty to us.
The Story Continues - Two Brothers and their Babysitter
Michelle has known Johnathon and Robert since they were born. In fact, she was one of their babysitters when they were kids—creating a bond that’s lasted a lifetime. What started as a childhood connection grew into a trusted partnership built on mutual respect and a deep-rooted commitment to each other.
Our business isn’t just built on numbers and spreadsheets; it’s built on generations of real, lasting relationships.
