Mark Gelfo

  • AP-BDC Certified
  • AP-O&M Certified
  • AP-Homes Certified
  • LEED Fellow

Mark was one of the founding members of the USGBC North Florida Chapter in
2004 and has been a consistent leader within all levels of USGBC ever since.
Having served as long-standing North Florida Board Member, Education Chair,
and as Chapter Chair several times, Mark now also serves at the USGBC
national committee level as Vice Chair of the LEED Advisory Committee and on
the LEED Steering Committee.

Mark has been a practicing electrical engineer for more than 22 years,
specializing in healthcare design, emergency power systems, sustainability,
and commissioning. He led TLC's Jacksonville office for over 10 years,
managing numerous noteworthy healthcare and sustainable design projects prior
to stepping into his current role as TLC’s Director of Energy Services,
where he leads TLC’s corporate wide sustainability and
energy services efforts, including commissioning, LEED, and high performance engineering

Mark employs a “work hard, play hard” philosophy, so when he’s not
working, Mark enjoys running and training for races. Although he has
completed three full marathons, he swears “never again” and is content to
stick with half-marathons and shorter races. Mark is also a self-proclaimed
science fiction nerd will be happy to tell you why Kirk is better than Picard
or why Batman is better than Superman.

Mark is originally from Allentown, PA and is a proud alumni of Penn State
University with a Bachelors in Architectural Engineering. He currently lives
in Jacksonville, FL.
