About Us

M Squared Accounting is committed to the financial and accounting needs of its clients. We partner with individuals and small business owners to help build their business, craft a fiscally responsible and sustainable business model, and redefine their own path to success.

Monique McDonald

President & Accounting Director

Monique first fell in love with accounting during her high school accounting course. Ever since, Monique forged ahead into an expanding tax and accounting career. Since obtaining her Master’s in Accounting and Financial Management, Monique began considering entrepreneurship. In 2017, Monique walked away from a job she loved to pursue M Squared Accounting on a full-time basis. Because of her more than 10 years in accounting and 12 years in tax preparation, at the time, Monique knew it was a walk of faith and a prompting to pursue her calling. She was called by God to help people find freedom from financial bondage. It is not always an easy conversation, but it is a necessary conversation. M Squared Accounting exists to help solopreneurs, entrepreneurs, and small business owners discover their own financial journey and define their own path to success.

Leslie Best

Senior Income Tax Director

Leslie began her tax professional career in 1989 with H&R Block. She further expanded her technical experience when she became the Tax Advisor at Kadena Air Base in Okinawa, Japan. Since her return to the United States, Leslie has worked as a Legal Assistant and Tax Advisor at Fort Lee Army Base near Petersburg, VA, and as a Tax Advisor and Tax Specialist at Joint Base Myer-Henderson Hall in Arlington County, VA.  Her nearly 30-year connection with the military, both at home and abroad, has exposed her to various tax situations like Injured Spouse, Foreign Earned Income, and others making her a wealth of knowledge for our clients. As a believer in Jesus Christ, Leslie has devoted her life to serving Him both in and outside the church. Her true ministry has been helping people on their own financial journey. There was a point in time where debt restricted her, and her family’s lives. Sewing her financial seed brought increase when she saw no way out. It was her encounter with God and her relationship with Him that began to turn her situation around.
