On October 4, 1924, Harvey H. Blank and Warren E. Fenstermacher opened the Grand Theatre in East Greenville, PA. It was designed and built by Souderton, PA architect Jerome S. Landes, who was also the designer and builder of The Palace Theatre in Quakertown, PA and The Broad Theatre in Souderton, PA. The Grand was to be the most modern and beautiful theatre in the Upper Perkiomen Valley. At the same time Blank and Fenstermacher built The Grand, William W. Bieler built and owned the restaurant in the front right corner of the theatre's "footprint". Through the window in the lobby, ice cream and other treats were sold as this was the theatre's only concession area.

In May of 1945, Warren Fenstermacher passed away, and his 50% interest in The Grand was inherited by his son, Linwood K. Fenstermacher. In December of 1951, Harvey Blank’s 50% interest was sold for $10,000 to Linwood Fenstermacher. Linwood became full owner of The Grand. In January of 1953, Linwood and his wife sold 50% of their interest to June Clarke (Linwood’s daughter) and her husband.

By August of 1966, The Grand, at 42 years old, was showing its age. The operator of The State Theatre in Boyerton, PA, Mr. Jack B. Kline and his son Mr. Jack H. Kline, leased The Grand from Fenstermacher and Clarke. The Grand closed for a 5 month renovation project that newly transformed The Grand Theatre into The Valley Theatre.

On January 20, 1967 (advertising the former Grand as "Everything New Including the Name") the Kline’s officially opened The Valley Theatre as a 7 day a week operation. The Valley boasted improvements such as a newly renovated lobby and concession area, new carpeting, new auditorium curtains, and a modern marquee. The younger Kline, Jack H. became the manager of The Valley.

By January 1970, after 3 very successful years of leasing the building, the Kline’s purchased the building from Fenstermacher and Clarke. In July 1975, the Kline’s sold The Valley to Thomas Thornton Enterprises, due to Jack B. relocating for his job.

January 1977 saw The Valley closed for many months by Thomas Thornton Enterprises. The Kline’s bought the theatre back, completed additional repairs, and re-opened The Valley under the care of Mr. Doug Bricker as Manager until Jack B. returned to the area.

In the Winter of 1982, extensive remodeling was done to The Valley, featuring new seats, a new heating system, new concession stand, new draperies, new carpeting, and a brand new Kintex sound system.

In September 1987, the Kline’s sold The Valley to Ms. Wanda G. Kerver, who also owned and operated The Broad Theatre in Souderton, PA.

The Valley, the last remaining theatre in the Upper Perkiomen Valley, showed its last film and closed in March 2004. All equipment and seating were removed from the building as rumors circulated about the theatre's future. There is no doubt that the rather harsh Winters of 2002 and 2003 accelerated the decay of the compromised roof. Sections the auditorium ceiling began to collapse. Everything left inside was drenched.

On August 20, 2004, Souderton Real Estate Agent Ed Buchinski and his business partner John Schortz purchased, and subsequently christened the building. Buchinski and Schortz’s company, Grand-Valley Holdings, LP, announced that the building would be saved from demolition. Several weeks later, after an extensive evaluation of the building’s condition and hidden historical elements, Buchinski and Schortz announced their final plans to embark on an extensive restoration project to return the building to its spectacular 1924 appearance and continued use as a theater. As part of the restoration, the original name "The Grand" would be used for the first time in almost 40 years. Following "modern times", the spelling of theatre was changed to theater.

On October 4, 2004, The Grand Theater turned 80 years old. Gifts included a new roof, new HVAC, and a very bright future!
