Laboratory Supervisor/Senior Field Technician
Juell is the brainpower behind our lab. He’s a math expert and a walking ASTM. He’s basically an engineer in technician’s clothing. Not only is he a master in the lab, he also performs just about every role in the field when needed. When he’s not at work he enjoys reading sci-fi fantasy.
Larry Jacobs, PE
Senior Principal Engineer
Larry is recognized as the expert in geotechnical engineering in our area and has worked across the southeast from North Carolina to Texas. Larry began his career in the Navy’s Civil Engineer Corp in Vietnam and came to Pensacola while in the Navy. In 1976, Larry founded Larry M. Jacobs & Associates, Inc. When Larry is in the office, he can’t hide from his world famous laugh, and when he’s not, he’s probably working on the “Honey Do” list or cruising in some exotic location with his “lovely bride.”
Keith Jacobs, PE
Keith started working at LMJ behind a drill rig at the age of 15. He graduated with honors from UCF with a Bachelor of Science in Civil Engineering in 2002. Since then, Keith has gained extensive expertise in geotechnical engineering on more than a thousand projects. As president, Keith picked up where his father left off and is committed to leading the company with the same values. He has an identical twin and is outnumbered in a house with four little girls (including his own set of identical twins) and a little man.
David Liechty, PE
David graduated from the University of Florida in 2001 with a Bachelor of Science in Civil Engineering. He worked for 7 years as a Civil Engineer before joining LMJ in 2011, and we think this geotech stuff is starting to grow on him. When not at work, David is spending time with his wife and three sons and enjoys hunting, fishing and being a weekend wannabe farmer with his garden, chickens and goats.
Jesus “Manny” Colon
Lead Field Technician
Manny began working as an engineering technician in Puerto Rico in 1997. He has worked at LMJ since 2003 and is a true professional. Manny is also our pile expert, and his specialty is augercast piles. Manny’s kindness and professionalism are infectious, and he keeps the spirits high for our team.
Don’s nickname is “Captain”, and he is our veteran driller. After serving in the Air Force, Don went to work at LMJ in1983. Don undoubtedly holds the record for most borings drilled in the area (and he has done most of his damage on a Mobile B-40 drill rig built in 1963, which he won’t let anyone else drive). When he’s not drilling, he likes to watch football, fish, and hunt.
James began his tenure at LMJ as a field technician and after learning the ropes in concrete, densities and piles, James began working in the field with our hump-busting drill team. There he began honing his skills in soils under the watchful eye of our most senior driller. Hailing from the University of Florida with a Master’s Degree in Architecture, James now combines his hard-earned skills as the newest member of our Project Management team.
Terry has over 18 years of experience. He graduated with a Bachelor of Science in Geological Engineering from the University of Missouri-Rolla in 1995. Terry’s expertise is in geology and hydrogeology, and he has worked in Texas with expansive soils and in Birmingham with Appalachian soils before coming to LMJ in 2002. Terry also does our Phase 1s and tends to be the voice of calm around a bunch of hyper people. He’s not a morning person, but he’s usually the last person to leave every day.
