About Us

Griffin Accounting began in 1997 when Terry Griffin started preparing tax returns from his home to earn extra income. What started as a modest side business quickly grew through word-of-mouth referrals and client trust. By 2008, Terry transitioned to full-time work from his home office, steadily expanding the firm's services to include payroll, bookkeeping, tax, and estate planning—laying the foundation for a full-service accounting firm.

In 2010, after passing the IRS Enrolled Agent exam, a second office in downtown Port Huron was opened to offer IRS representation and comprehensive support for local small businesses. However, limited parking and accessibility challenges led to the decision to close this location in

favor of better serving clients elsewhere. 

In 2012, Griffin Accounting experienced significant growth with the acquisition of Webb Financial Services in Wadhams, expanding the client base to over 2,300.

By 2014, the office could no longer accommodate the growing team. A larger space was opened on Krafft Road in Port Huron, and in 2015, the Wadhams location was merged into this new space, bringing all staff together under one roof, offering convenient front parking.

In 2022, Griffin Accounting acquired All Needs Tax, enhancing services for clients in Marysville and the southern region. Barb Chase, the owner of All Needs Tax, graciously continued serving her clients at Griffin Accounting until her well-earned retirement in 2023. 

After ten dedicated years in Port Huron, and with a lease renewal approaching in 2024, Terry and his wife Patt made the decision to merge the Port Huron and Marysville operations. In October 2024, they proudly opened the new office at 1140 Gratiot Blvd, Marysville, MI, located in the Market Square Plaza. This transition enables Griffin Accounting to continue providing outstanding service to our longtime clients while extending our reach to new communities across St. Clair County and throughout Michigan. Our dedication to personalized accounting solutions remains at the heart of everything we do.

Terry and Patt, along with friends, staff, and family, dedicated their entire off-season to personally build out the new office. To keep costs down and maintain a familiar, welcoming feel, they repurposed items from their previous locations, including doors, desks, trim, and even the full kitchen, which is now a much-needed break room for the staff. Moving items to the new office helped maintain the comfortable, home-office atmosphere that was originally cultivated back in 1997 at the inception of what is now known as Griffin Accounting. Terry and his wife Patt would like to extend their heartfelt thanks to everyone who dedicated their time, energy, and support in preparing the new office space. Your hard work and commitment have not gone unnoticed.

As Terry and Patt take a step back, and a new generation steps forward, we are honored to continue to serve you and we look toward the future of Griffin Accounting.
