Brett McKinstry

Brett McKinstry
PE, LEED AP BD+C, President/COO


Brett joined TLC In 1994, already experienced in mechanical design and project management on major buildings and after leading TLC's Ft. Myers office through years of rapid growth, Brett assumed the reins of COO in 2009. Brett fills many roles - managing operational challenges, facilitating change, chasing major business opportunities and solving mechanical engineering conundrums. Engineering is clearly Brett's passion and he's as likely to start drawing you a diagram of the solution as he is to ask you what you did today to make TLC a better place, for clients and staff. Brett’s knowledge of the A/E/C industry, experience on a wide variety of building types, forward-looking vision and affable disposition combine into a team player who leads by example.

A strong work ethic, providing for family and love of the USA comes from his immigrant father who came and found the American Dream. When not on the clock at TLC, Brett's passions are home improvement projects and building "stuff", from a bathroom remodel to a Tiki hut addition. Relaxing time is spent outdoors, usually on his bay boat, "Touch of Gray" with son or friends "wetting a line".

Brett's BS in mechanical engineering from Virginia Tech is proudly displayed in his office - and you're likely to see him wearing a Hokie shirt or hat as he heads out before dawn on a fishing trip.

Robert D. Danner

Robert D. Danner
Vice President 


For more than 30 years, Bob's been crafting solutions to client challenges at TLC. He diligently worked his way through the ranks, rising to become Director of TLC's largest operating unit, Healthcare, and managing the team responsible for delivering literally hundreds of successful projects around the world every year. Like many of TLC's senior healthcare staff, when the state of Florida contracted out document review and building inspections for healthcare facilities, Bob focused specifically on this effort, making him a very well- versed design professional in understanding the complexities of Florida's healthcare codes, specifically in the electrical discipline. In addition to assuming full responsibility for the Healthcare Operating Unit, Bob was appointed to serve on the firm's Board of Directors in 2015, bringing his years of experiencing the TLC culture to shape the future of the firm.

Bob's family influences his non-work hours. He is often assisting his mom, bringing a special understanding of the expectations and needs for our country's issues in caring for our elderly. Equally important is his and his wife's involvement and support to their adult son who teaches and coaches today's youth, just as Bob influences TLC's younger engineers. Whether it's on a volleyball or basketball court, or in the healthcare studio, Bob teaches the importance of working as a team to achieve common goals.

Born and raised in North Carolina, Bob's nearly become a Florida native, proudly calling Orlando home since the early 1970's. He's seen firsthand the many changes in central Florida as Disneyworld opened and created the hospitality industry. The rapid growth of central Florida and resulting demand for high quality healthcare has kept Bob busy - and will for years to come.

A. Brian Lomel

A. Brian Lomel


Brian's years of mechanical engineering shine through his quick wit, ability to demonstrate to developers that quality building systems are worthwhile and his commitment to improving new and existing buildings, for the occupants, operators and owners. Recognized for his story-telling approach to educating and sharing information with industry partners, Brian uses his sense of humor to apply his knowledge of how buildings really operate and how building occupants do not always use the building as intended to make his points about simplicity in design and operation. Brian's ability to translate engineering jargon into business language and numbers and vice versa helps his client get the most out of their design team. Prior to his current role in advising building owners on how to achieve sustainability goals, Brian managed the firm's South Florida office and he has built a vast network of really smart people throughout South Florida and across the country.

Brian and his wife Angela, along with fur children Busy and Lolo, reside in Wilton Manors. They're frequently found in Tiki Bars or on the way to a great concert. He will tell you that it is “great to be a fuzzy bee” from Georgia Tech, graduating with a Bachelor's degree in Mechanical Engineering. In addition to being a LEED AP and a CxA, Brian is among the first WELL APs in the country, demonstrating his leadership and commitment to health and wellness in building design. That commitment to wellness inspires him to run, even if it's only to the next great restaurant.
