Leadership team

Tim Lietaert President & CEO

Tim Lietaert experienced his first glimpse into the glass business when he was invited to work for the glaziers who replaced the windshield on his ’66 Ford Mustang. Until then, Tim had worked seven years in retail with Long’s Drugs, where he became the youngest department manager in the district.

Glazing was a challenging and exciting field, but he quickly identified problems within the glass industry — disorganized project management, missed deadlines and miscommunication. With his background in retail customer service, these qualities weren’t acceptable to Tim, then or now.

After leaving and being drawn back to glazing several times over the years, Tim, a tenacious and service-oriented leader, realized he could take his depth of experience and use it to build a better company. He knew success depended on working with integrity, transparency, and trust and treating people well, so it was fitting when a previous client heard of Tim’s plans to found his own company and offered to help him get started. That meeting led to the day in October 2000 when Glazing Concepts opened its doors —for Tim, further proof that relationships are key, and that relationships can bring opportunities.

Over the past 18 years, Tim has led his company by example and established a culture of giving — giving top-tier service to clients, giving his employees opportunity for personal growth in their positions and giving back to the community. At work and at home, he and his family are active supporters of Make-A-Wish, Leaps & Bounds, Relay for Life and more.

Robert Cianciminio Chief Operating Officer

Robert Cianciminio joined the glazing industry in 1991, working first with a manufacturer of glass doors and a variety of fabricated glass, then as an estimator. It was during his time as an estimator that he first worked with Tim Lietaert. For much of the 2000s, Robert owned his own business customizing cars, but returned to the glass business in 2008, this time with Glazing Concepts. Given his and Tim’s history working together, it was a fit in both timing and opportunity.

Beginning in 2008, Robert worked his way up the ladder from a service manager to project manager and finally to his current position of COO in 2018. As COO, Robert oversees daily operations in the field and in the shop — managing schedules, reviewing the team and, primarily, ensuring labor comes in within budget.

Robert believes in Tim’s service-oriented vision for GCI, and he furthers it in day-to-day operations by encouraging positive, genuine group morale. He makes a pointed effort to wish the team well at the start of a day, check in with them at the day’s end and remind them his door is always open.


Greg Olney Chief Financial Officer

Greg Olney brings decades of financial and business experience to Glazing Concepts. Before joining GCI, Greg was the Director of Shared Services at Automatic Data Processing (ADP), where he served for 22 years. Previously, he worked with Vubiquity, Fleetwood and Washington National Financial Services. In addition, Greg is a published author of multiple books on change management.

After leaving ADP in 2007, he founded his own business consulting company, and in that time, he met and began working with Tim Lietaert through a mutual friend. After closing his consulting business and working with Vubiquity in Sherman Oaks for four years, Greg found himself looking to move work closer to home. At the same time, Tim was searching for a Vice President of Finance who espoused likeminded principles. Over the course of their discussion, Greg was drawn by GCI’s technical superiority compared to other contractors with whom he’d worked, as well as by Tim’s heart for social responsibility. He joined Glazing Concepts full-time in 2014 and has since then been promoted to CFO.


Chris Carranza Project Executive

Chris Carranza, having worked dutifully as the Project Executive at GCI, wasn’t always the specialist on Glazing that he is today. Having started off doing electrical work, Chris found his first opportunity with Glazing through a mutual friend. After learning the tricks of the trade, Chris brought his expertise over to Glazing Concepts and has contributed immensely to the company over the last 7 years.

On the day-to-day, Chris oversees project managers and assures their ability to see their projects through. His duties come in the form of troubleshooting new issues that arise and resolving questions regarding hardware compatibility, accounting programs, and subcontracts. Chris additionally establishes collaborative efforts to identify client concerns and ensure their satisfaction while maintaining accountability practices throughout the company. Knowing that accountability contributes greatly to their success, Chris upholds the sentiment that there is always room for improvement.

Chris spends his free time coaching his 13 year old son in youth football while his 7 year old daughter cheers for the win. Chris explains that being involved in youth sports with his kids is one of his greatest passions and feels as though there are few moments that you can find children happier than when they are sharing in outdoor fun with their friends. Chris additionally feeds his football interests by coaching the Norco JAAF mom’s  each year for the Annual Pink Bowl in an effort to raise funds for Support Sisterz which provides financial support to women undergoing breast cancer treatment.
