Meet Our Team
David Gelinas is the Director of Education and Training for 1800MarbleGuy. David is responsible for doing the education & training for all of our field technicians in the various services we provide but also for doing all of the safety training as well. David is committed to making sure our Techs are able to provide the highest level of service possible but to also do it with the highest commitment to safety.
David has decades of experience in projects from small residential restoration work, historic restoration & preservation (private & municipalities), as well as extremely large commercial and industrial projects. He has worked on and consulted on projects from Skaneateles, New York to Guaynabo, Puerto Rico. He is routinely asked for technical advice from both suppliers and fellow contractors from across the country. David also sponsored and wrote the curriculum for a school dedicated to stone restoration and has been a guest instructor at other nationally respected stone restoration schools. He has also been asked to serve as a judge for industry publications and trade events as well as one of five founding members of a stone restoration trade association. David also holds at least one industry related patent.
David originally started his company when he was 16 years old. In the decades since, he is very grateful to have had experience in countless aspects of both his industry as well as closely related industries. This knowledge and experience along with ongoing education is an invaluable blessing that he is able to share with our clients, our technicians (that are such a big part of our success) and with fellow contractors.
The reason David started his company when he was 16 was to have a schedule where he could do volunteer educational work. It wasn’t until he was 26 when was able to finally meet that goal of being able to do that and he has continued ever since, with the exception of one year due to health reasons. Today he tries to average at least 70 hours a month spread across three primary areas of volunteering; educational work, assisting with safety training in construction & maintenance, assisting in emergent health situations involving surgeries and non-blood related cases in several local hospitals.
David is a native to St. Petersburg and has a tremendous love and appreciation for this area. When he has the rare occasion, he loves to ride any number of his bicycles (he only has 11). It could be riding their tandem with Denise, riding his road bike with friends or single track riding his mountain bike with his brother Rick and his wife Nancy or riding one of his Old School BMX bikes with his grandkids, Ollie & RubyG.
Dense Gelinas is the primary owner of 1800MarbleGuy, that makes her The Boss and the #1 Marble Girl! Denise has been overseeing the day to day administration of the company since she married David back in 1985. Along with what she continues to still do for the company, she also focuses as much of her time as she can on doing the things that a business owner, wife, mother and grandmother does, as well as spending as much of her time as she can doing volunteer work with David. Over the years Denise has received hand written thank you letters and notes from our clients, saying how much they appreciate all that she has done for them.
