Get Financial Clarity in 15 minutes

What changes with MASCPA?

MASCPA works with service and trades businesses when growth creates cash, job, and tax complexity. We install financial systems that evolve as the business grows, without forcing yearly overhauls.

  • Mark, and his whole team, have been absolutely incredible! I had a mess of a situation in growing my business and they tirelessly combed through each component to set it all straight. Mark adds a personal touch and personally called me on multiple occasions to sort everything out. As a small business owner, my taxes and accounting is certainly not where Mark’s team will make their money so the fact that he went out of his way to accommodate me means a lot.

  • I started using Mark’s services for my business, and liked him so much I had him take over my personal as well! Mark has a great process, is easy to work and communicate with, and is skilled at utilizing modern methods and systems to better streamline your accounting. Highly recommend!

  • Mark has been my CPA through the start of two successful businesses.  He, and his team are responsive, thorough and very helpful.  I recommend his services with zero reservations!

  • Very happy with Mark’s customer service, quality of work, and ease for which he conducts all aspects of business! I would recommend it to anyone!

  • My rating is best available since Mark, Nicole and the team have earned it by demonstrating throughout the process of delivering accountancy services that they are genuinely dedicated to delivering a “professional service” I can count on; passionate about getting it done swiftly and reliably; and, earning this client’s trust and confidence along the way.  I’m quite fortunate to have them.

  • We have been using Mark’s services for the past three years and could not be more satisfied with the results! Filing taxes is the one thing that you know you have to do every year, and knowing that you have a caring professional to support you makes this necessary task so much easier.

    With Mark and his team, we feel confident that our taxes are filed correctly and on time. He makes himself available to answer questions. I know that he must have many clients, but he makes us feel like a priority!

    Before Mark, we used online platforms and we will never go back! For the same price, we get the compassion and confidence of a trusted professional who we know has our best interests in mind
