Premium glass solutions that elevate both form and function
Founded in 1977, Diamond Glass Company began with humble roots in a small office-warehouse on South Main Street in Alpharetta, Georgia.
Over the past 49+ years, founders Andy and Susi Kalifeh along with Bob Kuhn have grown the company into a trusted leader in the glass and glazing industry, expanding into Sanford, Florida in 1987, and successfully completing over 250,000 projects across residential, retail, and commercial sectors.
Under the leadership of Andy Kalifeh and Bob Kuhn, Diamond Glass Company remains committed to offering top-tier service, fostering a supportive environment for employees, and giving back to the community.
Our passion for both our customers and our team drives everything we do.

Years of Experience
“If you can think of it and it’s made of glass, we’ve probably done it at least once.”
In 2019, Diamond Glass took a significant step in preserving local history by acquiring the St. James United Methodist Church building next to our headquarters. Built in 1963, the church was originally founded by a group of freed slaves a century earlier. To prevent its demolition and honor its legacy, we repurposed the building as our executive offices—ensuring this vital piece of history remains an enduring part of our community.
At Diamond Glass, we don’t just deliver exceptional glass solutions; we’re deeply invested in preserving the past and shaping the future.
Our team here at Diamond Glass Company is dedicated to quality and service. The team consists of very qualified project managers, estimators, glaziers, glass installers, and technicians with many years of experience.
