About Us

I started my career with a Big Four public accounting firm, working with entrepreneurial and non-profit-based organizations, and it was during these years that I realized that while I loved the work, my true life goal was to follow my family’s tradition of owning and operating my own business. After fulfilling this goal in 2012, I vowed to build an accounting practice based on the premise that I’d treat clients just as I do my friends and family. I pride myself as a hard-worker who learned that trait through my upbringing and working in my family furniture stores through my teenage years.

My family and I now live on Capitol Hill, where I enjoy the city’s vibe and am excited to see how small businesses continue to reshape the landscape. We’re dedicated to Washington D.C. and have chosen to raise our family here. No matter where you’re located, we consider you a part of our community and understand that your life goals become ours.

Prior to starting the J.S. Miller Group, I:

• Was an Auditor with Ernst & Young and KPMG.
• Worked as in-house CPA for Marriott International’s Internal Audit and SEC Reporting Group.
• Held the position of CFO at Universal Air Travel Plan, a global financial services firm, responsible for all financial and risk management.
• Earned an MBA from The George Washington University.

Then in December 2012, I started the J.S. Miller Group.
