Meet the Owners

Hello! I’m JR Pentolino. I am a licensed glazing contractor, and my wife Natalie and I own and operate ClearChoice Windows and Doors in San Dimas, CA.

We are a Christian family that runs our company upon biblical principals. We care deeply about our customers and our business, and strive to put out the best product we possibly can.

I got my start I started in the window industry in the late 90’s. During that time, I have seen a lot of changes in the industry. The quality of the windows has improved. Energy efficient glass has gotten much better. There are more options than ever.

We are happy to explain your options to you and help you find a window package tailored to meet your personal needs.

What Our Customers Have to Say

We hired ClearChoice to replace all 24 windows, a sliding glass door and an entry door and all of the interior doors. Everything turned out perfectly. The installers showed up on time, and got right to work. And the work was flawless.

Kristen W. Rancho Cucamonga

The windows are beautiful and have really changed the look of our home.  From first meeting Billy to the end with the installers we were very pleased.  If you are looking for windows this is company to talk to.

Angela B. Garden Grove

I can’t recommend Clear Choice highly enough. I have worked with three other window and door contractors in the past and have NEVER been happy afterwards until Clear Choice.

William B. Pasadena

The difference in the house is amazing, with no noise and temperature stay the same and it is easier on the A/C to maintain temps. We are happy with the whole experience.  Thank You Clear Choice!
