The Sunderland Group, Inc. 3000 Center Green Drive, Boulder, CO 80301

"I would give Mark Sunderland 0 stars if I could. We hired him as our CPA last year and it was a massive mistake. He did nothing to save us any money on our taxes and his communication is horrible. He does not explain anything clearly and when we tried to ask him a question about how much we should pay for our quarterly tax payment he sent us an invoice for almost $500 for his time to answer a question that took him probably 5 minutes to respond to about information he should have given us to begin with. He’s also rude and sarcastic in his email responses. I would highly recommend looking elsewhere if you need help with taxes."

"Excellent accounting firm. We use Sunderland for monthly accounting as well as year end tax returns. They're very knowledgeable, responsive, and professional. Because they do monthly accounting, they are in touch with us regularly and contact us whenever they see new line items that they haven't seen before the make sure we know when new charges come in. They spent 6 months auditing our prior years' accounting and fixing any mistakes we had. Very highly recommended small business accounting firm."

"Excellent Service and Professional Staff. I have used The Sunderland Group for several years and have always been pleased with the care and services provided by the team. They offer a great online tool and offer flexibility in face to face meetings as needed. It’s great to have a honest, competent and friendly CPA that’s in Boulder. I would highly recommend The Sunderland Group for your personal and small business CPA needs."

"The Sunderland Group has taken care of our personal tax returns for the last few years with out any problems. Usually near the beginning of the year, we get an update engagement letter which spells out all the deadlines we need to meet in order to get our tax work done. Its very helpful to know what you need to provide and by when. Since their a smaller firm, I understand they don't have hundreds of people sitting around waiting for my paper work like a H&R Block but, can you trust a firm like that?"

"We have worked together with the Sunderland Group for a number of years now and each year gets better! Their client portal is so easy to use to review all of our business and personal finance and tax documents. The Sunderland Group sets specific dates to submit documents for tax time and those dates are very clear. We have learned that it is very valuable to meet with Mark on a regular basis to review our accounts and where we stand. They also helped our small business change from an LLC to an S-Corp, which was beneficial for our taxes."
