Meet the Team


I am David Miller, and I am the founder of Miller CPA. I completed my undergraduate degree in Accounting at UMass Dartmouth in 2013. Then went on to get my Master of Business Administration with a concentration in Tax and Law at Bentley University graduating in 2015. The same year I also became a Certified Public Accountant (CPA). Before I started this practice, I had 2 years of experience in Cost Accounting, 4 years in Public Accounting, and 4 years in Corporate Tax at a Biotechnology company. Outside of work, I enjoy golf, boxing, and my wonderful dog, Juno. Juno is a Husky/German Shepard mix for those who are wondering 🙂


My name is Brittany Lewis and I have worked as the Office Manager for Miller CPA since 2019 but have been working in the accounting world for over 10 years. I am a Hartford graduate. Parks and Recreation is my favorite show. I am considered the coolest member of the team.


I am Liam W. Millens, a Tax Associate at Miller CPA. My background includes the completion of an Undergraduate degree in Mathematics from the University of Vermont in 2021. In January of this year, I earned the distinction of becoming an Enrolled Agent, and I also hold the title of Certified People Advisor for Gusto. Beyond my professional endeavors, I have a strong passion for sports, particularly basketball, football, and rowing, as well as a deep appreciation for the outdoors.
