I have know Mark for years, however, just recently started doing my taxes with him and his team. I did not make this decision without much thought as the old rule of thumb is don't do business with friends . Well, I broke the rule and could not be happier. Mark and his team are amazing. They are on time, accurate, helpful and always available. I can't say enough great things about The Sunderland Group.

My only regret as far as hiring Mark and his team is that I didn't get their help sooner. When my wife and I started our business, things were so simple: (not so much) money coming in - money out + turbotax = happy IRS + happy us. But as our business grew over the years, the shadow and terror of the U.S. Tax Code started to creep slowly into our lives, drowning in paperwork, obscure rules, and estimated tax payments. Dun-dun-duuun! Anyway, we found out we were really screwed and that my training as a PhD in Aerospace Engineering hadn't really prepared to deal with the almighty IRS when we applied for a home loan. Boy, you think dealing with IRS is tough? They got nothing on home loan underwriters. Enter Mark. I searched on Yelp for an accountant, and his name came up. I scheduled an appointment. I went into his office feeling like an idiot because at our income level we should have gotten an accountant years ago. He was super friendly, devoted a lot of time to listening to us, and knows more about the monstrous tax code that I could ever hope to learn. More importantly, and what really sold it for me after talking to other accountants, was that he understood what our business was about. Our business model is unconventional -- we sell eBooks and other printable goods. As simple as that sounds, people have a difficult time comprehending how we make money. Mark didn't. He asked us several specific questions about the business, until he really understood what it was about. Fast forward a few months, our business is still going strong, we do not feel the cloud of the IRS over our heads, and we have a better plan for paying payroll and estimated taxes. Granted, we never leave Mark's office happy, as he always has a accurate idea of the exorbitant estimated taxes that we have to pay; but we do leave satisfied and confident that the IRS won't be knocking on our door anytime soon. I highly recommend Mark and his team!
