About Kathy Moore-Nietrzeba, CPA
Kathy Moore-Nietrzeba prides herself on her over 30 years of experience working in the accounting field. Kathy is a Georgia native who received her Bachelor’s degree in accounting from Kennesaw State University in 1987. Kathy began an internship at age 21 with a CPA firm that specialized in working with medical and dental practices. This internship later turned into a 17-year career there and grounded her desire to continue working with medical and dental groups. It was also during this tenure that she became a CPA knowing that one day she would open her own CPA firm.
Kathy started her first CPA firm, Moore & Associates, in 2004 where she established herself as an expert CPA in the medical and dental niche. From there, Kathy merged her firm with a local wealth management firm and supervised the Accounting and Tax Department bringing in interns from Kennesaw State University, training them and even eventually having one of them come back and work with KMN CPA and is with us today – Whitney Boyd.
It was in 2014 that Kathy decided to relaunch her own firm under a new name, KMN CPA LLC. She was then able to tailor her services directly to her clients’ wants and needs by providing them with an optimal level of service, whether it is in person, over the phone or virtually. Kathy is also a proud member of the GA Society of CPAs.
Kathy lives in Marietta with her husband. She has two children and three grandchildren. During her free time, Kathy enjoys her family and church, leaving some time for personal fitness and travel.
