Since its founding, Muhlenberg Greene Architects lists over 3,500 commissions to its credit,[1] including many landmarks in the city of Reading, such as Berks Heim, the Reading Medical Arts Building, and Stokesay Castle.

Officially retiring from the firm in 1977,[12] one week after his 90th birthday, Mr. Muhlenberg still came to the office daily until physical limitations prevented him from doing so about a year later.

Following Mr. Muhlenberg's retirement in 1977, the Firm became the sole proprietorship of Lawrence A. Greene, Jr, (who had, at that time, been a partner of the firm for 25 years)[12] until January 1, 1980 when the present corporation, Muhlenberg Greene Architects, Ltd., was established.

The original principals/stockholders were Lawrence (Larry) A. Greene, Howard Quaintance, and James (Jim) E. Dockey.

The current principals are Larry Greene, Howard Quaintance, Dennis W. Rex, and John R. Hill.
