SOUTHFIELD, Mich.--(BUSINESS WIRE)--Atwell has named Sean McMillen as Chief Financial Officer (CFO), succeeding longtime CFO Roderick Petschauer, who will retire at the end of September after nearly 16 years with the company.

During his tenure with Atwell, Petschauer has been a key member of the leadership team, helping guide the company through significant growth and change. His financial leadership and steady guidance have helped position Atwell for the future.
