“Donovan really cares about what his clients do. Sure, he can geek out on tax codes and regulations… but how many accountants really get into what their clients are doing?”

- D.M., CFO of various Technology and Biotechnology Companies

“Donovan? Two Words: The Best.”

- P.F., VP – Tax

"DTB provides tax advisory services for a number of companies in my portfolio and client list. DTB’s “big 4” origins ensures highly sophisticated and impactful advice nationally and internationally for a variety of entities from venture backed Delaware C Corps to S Corps and LLCs. However, the firm behaves like a personal partner – you get calls returned almost instantaneously and their pricing is well below what you’d spend with an international or national firm."

- M.D., Founder, CFO and COO of various BioTechnology and Technology Companies


"We can't give enough praise for the professional service provided by all DTB staff over several years handling our business inquiries, and returns at year end. Donovan is the man for all of our tax related needs."

- S and B, Personal clients


“I have been working with Donovan for many years. He has tremendous knowledge and experience which translates into exceptional business and personal tax strategy and execution. I’ve worked with many others and there’s no question that Donovan is the best match for me and my business.”

- D.M., Founder and CEO of a Technology Company


"Like most business owners, I consider myself pretty practical. One indication of this is that I typically never pay for anything that I can do myself. In the first years of my company this was my attitude about accounting and taxes - we could input stuff into an off-the-shelf program as well as anyone else, so why pay an accountant? However, for the last decade or so we’ve used Donovan and I have no regrets. I never feel bad paying his invoices because I feel he provides us service and insights that I can’t get elsewhere. Over the years, I have recommended him to many other business owners for both their company's and personal accounting needs."

- M.D., Inventor, Founder, Chairman of the Board and CEO of various BioTechnology Companies


"Donovan Billings has served as tax practitioner and business strategist for a variety of my clients for several years. I can honestly attest that Donovan is the best in his field. His expert command of income tax regulations and technical GAAP accounting requirements has been demonstrated time and again. Donovan exudes an energetic passion for his work that results in first class service for his clients. He is articulate and conveys complex information with friendly confidence such that all involved can understand the issues, alternatives and the most appropriate solutions to be enacted. Although a ‘big picture’ forward thinker, Donovan has a strong attention for detail which is key for accurate and timely filings. Accessibility is important to me and Donovan always takes the time to promptly respond to inquiries as needed. As a fellow CPA, I respect Donovan’s professionalism and integrity and have consulted with him on personal tax matters because of the faith I have in his good judgment. I call Donovan a ‘tax warrior,’ an excellent resource to have on your team when putting strategies in place and maneuvering through year to year performance."

- P.H., Principal and CFO

"DTB Tax has been great to work with in my capacity as CFO of a venture backed start-up. Donovan and his team are very responsive whether it be strategic advice, tax filings, or a last minute copy of a misplaced tax return needed to complete a financing. Donovan has a true passion for tax and guides his clients on valuable timely tax advice so that good decisions can be made. I highly recommend Donovan and team."

- B.H., Venture Capitalist
