Meet Our Team
Preston Oles
Founder & Owner
With a passion for exquisite stone craftsmanship, Preston Oles is the driving force behind Granite Galleria. As Founder and Owner since 2004, Preston combines decades of hands-on experience in the stone industry with a strong commitment to quality, precision, and customer satisfaction. His keen eye for detail and dedication to excellence ensure that every project reflects sophistication, functionality, and timeless design.
Unlike many owners, Preston remains actively involved in the day-to-day operations of the business — from templating and saw work to fabrication and installation — while leading Granite Galleria’s experienced in-house team of polishers, installers, and waterjet specialists. His passion for craftsmanship and personal involvement in every stage of the process are what truly set Granite Galleria apart.
Outside of the shop, Preston enjoys surfing, snowboarding, mountain biking, hiking, traveling, and spending time with his wife and their four dogs.
Tina Vaganos
Director of Operations & Client Relations
Tina Vaganos has been an integral part of Granite Galleria since 2009, bringing exceptional organization, creativity, and professionalism to the company’s daily operations. A graduate of the The Wharton School, Tina oversees the administrative side of Granite Galleria with precision and care, managing everything from scheduling and client communication to accounts receivable/payable, financial coordination, design assistance, and the countless behind-the-scenes details that keep the company operating smoothly.
Often described as the backbone of Granite Galleria, Tina plays a vital role in ensuring every project, customer, and team member stays organized and supported. She is typically the first person clients, designers, and contractors interact with, and her warm personality, extensive industry knowledge, professionalism, and attention to detail help create lasting relationships built on trust and confidence. Customers appreciate not only her strong work ethic and people skills, but also her ability to make the entire process feel seamless from start to finish.
Her dedication and commitment have helped shape Granite Galleria into the respected family-owned company it is today. Quite simply, without Tina, Granite Galleria would not run with the same level of efficiency, care, and personal connection that clients have come to know and love.
Beyond the office, Tina enjoys golfing, relaxing at the beach, traveling, and spending time with her husband and two daughters. She especially treasures visiting Greece, where her family’s roots began, and creating lasting memories with loved ones while embracing the culture and traditions that remain close to her heart.
