Stephanie Kossaras, CPA, HCCP, Senior Manager

Stephanie is a senior manager in Maner’s Tax department, joining the firm after completing graduate school at Michigan State University in 2014. She provides tax support, planning and preparation to Maner’s for-profit clients, specializing in affordable housing and multi-state entities. Passionate about supporting clients in the affordable housing space, she offers consulting advice to clients on Section 42 tax credits and has passed her exam to become a Housing Credit Certified Specialist (HCCP).

In addition to her extensive affordable housing knowledge, Stephanie supports the firm’s Employee Benefit Plan specialty, helping clients ensure their retirement funds are managed properly through employee benefit plan audits.

Outgoing, friendly and driven, Stephanie is actively engaged in numerous initiatives throughout the firm. In 2021, she chaired Maner’s Employee Engagement Committee, leading the firm’s efforts to help increase engagement and belonging for associates throughout the pandemic. She continues to be actively engaged in the committee’s ongoing efforts.

Stephanie’s passion for accounting started in high school when she fell in love with debits and credits in one of her first accounting classes and decided to become a CPA. She worked in the Accounting department for the Lansing Lugnuts throughout college and grad school, gaining valuable experience prior to transitioning into public accounting. Always up for a challenge and someone who thrives in a busy environment, Stephanie’s goal is to become a partner at Maner.

In her free time, Stephanie enjoys reading, playing games of all kinds, spending time with family on the lake and relaxing up north. A graduate of Michigan State University, she lives in St. Johns with her husband and Maner colleague, Nick, three animals, Willow, Denard, and Zelda, and son, Geo, who the pair welcomed in the fall of 2021.

I learned early on that while I could look up to others in the firm, and always have role models or go to them for guidance, my career path, progression, and focus didn't have to look like someone else's, because we are fair but not equal.
