We have been clients of Mercer Flanagan for more than 20 years, trusting them with both our personal taxes and our business accounting needs. Throughout two decades of changing tax laws and business growth, their team has consistently provided outstanding, thorough, and reliable service. They take the stress out of tax season, communicate clearly, and always offer great insight and advice. Finding a partner you can trust for the long haul is rare, but this team has been a steady and invaluable asset to our family and our business. Highly recommend!

Mercer Flanagan did both my personal and business taxes and did a great job on both. Service was excellent throughout — responsive, organized, and no chasing him for answers. On top of that, his pricing was very reasonable for the amount of work involved. Highly recommend.
