Sherilynn De Maio


Hello neighbors! I’m Sherilynne DeMaio, owner of The Glass Guru of Carlsbad since 2012.  I grew up in the Massachusetts area, went to Colonial High School in Orlando, Florida, and then college at the University of Central Florida where I graduated with a degree in Education. 

Prior to The Glass Guru, I gained valuable experience in business ownership, restoration, and DIYing as in so many roles. From being a VP at a national bank, then I ran a business and later founded and directed a charity. After receiving my degree, I taught. With more twists and turns in insurance brokerage, I ended up joining my sister at The Glass Guru. 

I took over The Glass Guru because I enjoy meeting people and wanted to have a positive impact on my community. I am extremely proud of growing a great team and watching our excellent reputation grow. 

Outside of work, I enjoy reading and gardening. I have two amazing adult children, one dog, three grand kitties, and a soon-to-be son-in-law. On weekends you might find me exploring mountain trails or checking out local events and venues.

It’s a great honor and privilege to have the opportunity to serve you and we hope to be the local glass shop you can trust and rely on for many years to come. I love helping people find cost-effective ways of making their homes happier, prettier, and more comfortable. The Glass Guru enables me and my team to do that every day!

"Great experience with Glass Guru! I received fast, professional and high quality service. My technician (Sean) explained the repair process very well, and he did everything he said he was going to do. Sean was prompt and left the work area clean.

"Beautiful, clean, timely and professional work done by Jacob and the Glass Guru team. We had a previous shower door crash out of nowhere and felt confident that Glass Guru could install a better door and do it the right way. They sure did, and I’d highly recommend! In fact, I already did recommend to my neighbor and they successfully fixed her door a few days later."

"From start to finish I had a positive experience. When estimator came, he was on time and professional and friendly.

Jacob installed. He was fantastic! I wish I could clone him. Thoughtful about landscaping surrounding the window. Vacuuming and picking up debris. Seems basic, right? After building this house with one contractor and deck with another and garage with yet another, I have yet to find a worker who treated their task as if it were their own, until Jacob.

Thank you Glass Guru team! Grateful."

"Great customer service. I left a text asking for a quote via their website, and it was answered immediately. And no dancing around and trying to delay the quote or have you come in, etc. as many “get a quote” sites do. They just provided the exact price immediately."
