CPA, Senior Manager


Christy Sommers, CPA, Senior Manager

Christy joined Maner Costerisan in 2014 as part of a merger with McCartney & Company, PC. She brings 25 years of experience to the firm and specializes in supporting Maner’s telecommunications and nonprofit clients. In her role as a senior manager, Christy focuses on providing audit and attestation services. She also supports clients with their outsourced accounting needs and corporate taxes. An active member of Maner’s Telecommunications industry team, Christy is always looking for opportunities to grow as a professional and support her Maner teammates.

After completing two years of college, Christy switched from studying Aeronautical Engineering to Accounting. After changing her focus, she found she loved everything about accounting and realized right away she wanted to be a CPA in a public accounting firm.

Her passion for accounting has continued throughout her career, and while she loves numbers, she enjoys building relationships with clients across different industries even more.

Christy grew up in Davison, Michigan. After high school, she graduated cum laude from Franklin University in Columbus, Ohio, with a Bachelor of Science degree. She now lives in Brighton, Michigan, with her husband, Russell, and dogs, Einstein and Darwin, enjoying the small-time life. Christy enjoys reading (especially books by Steven King), remodeling and repairing her home, adult coloring books and apps, paint-by-number painting and spending time with family.

Her favorite quote is by Simon Sinek, author of Start With Why:

"Working hard for something we don't care about is stress. Working hard for something we love is called passion."
