Our Owner

Joe Pentolino started Design Windows and Doors Inc. in 2005. He already had 10 years of experience in the window industry at the time and realized that he had the tools and experience to potentially make an even better company. He's been guiding Design Windows and Doors Inc. to success ever since. Joe plays a huge role shaping the direction of the company both by making major decisions and simply making sure that the company maintains the commitment to quality workmanship and exceptional customer service that it was founded on.

When he's not working he enjoys spending free time with his two Chihuahuas and traveling. He also has a strong interest in American history, especially the old west.
