About Us

Since the beginning, our goal has been to hire the best talent. We’re proud of our team.
John Gemmi


Certified Remodeler, Certified Kitchen & Bath Remodeler

As president and founder of Gemmi Construction, Inc., John has always known he was destined to build. After graduating from Arch Bishop Wood High School and the carpentry program at Middle Bucks Institute of Technology (MBIT), he worked for 10 years for a prominent local builder before launching Gemmi Construction, Inc in 1997.

Valuing the education he received from MBIT and the opportunity given to him by a local builder, John has paid that philosophy forward by often hiring carpenters directly out of MBIT. John’s easy going manner and natural talent for elegant design have proven to be the ideal recipe to propel Gemmi Construction to the forefront of the industry, winning many awards in the process.

As a longtime member of National Association of the Remodeling Industry (NARI) both at the local and national levels, John has served as chair of the education committee and is a past president of the local chapter as well as a former national chair of the Contractor’s Council. He has been honored with the Billingham Education Award, the Spirit of NARI award, the Professionalism Award, the Community Service Award, President’s Award, and the very prestigious NARI Lifetime Achievement Award. John holds two NARI certifications including certified remodeler and certified kitchen and bath remodeler and he currently serves on the Advisory Committee of MBIT.

In his spare time John enjoys working on his 1967 Camaro, geocaching, catching the occasional car show, and spending quality time with his wife Lizie, their kids, cats, and the chickens who reside in a chicken coop built by John.

Lizie Gemmi



Lizie’s unwavering dedication to Gemmi Construction began in 1997 when she first met John and they developed a partnership, both in life and career. Lizie earned a Bachelor of Science degree from Delaware Valley University after graduating from Linden Hall School for Girls in Litiz, PA. While working as a Virologist at St. Christopher’s Hospital in Philadelphia, she began helping John with the business in her spare time. It quickly became clear that they were a great team and Lizie’s strong commitment to the success of Gemmi Construction made for an easy decision to transition to a career in the family business.

When time permits, Lizie loves getting into her garden, as well as knitting, cooking, and exploring the world with her family. Lifelong residents of Buckingham, PA, the Gemmis live in the home Lizie grew up in, with their kids, dogs, cats, and a whole bunch of chickens.

Brent Schuler



Joining the Gemmi family in 2014, Brent brings years of experience to the company. After working his way through college, he earned a marketing degree from Temple University and went on to a 30+ year career in the building industry. Working in tandem with John Gemmi, Brent oversees and manages all projects, listening to the client’s needs, and working with vendors, contractors, and design professionals to prepare cohesive estimates. From there, he expertly coordinates a plan of action on each job site with the full Gemmi team.

Away from work, Brent plays volleyball in a league and coaches his son’s volleyball and baseball teams. He is also an avid runner, and especially enjoys running with his daughter who is on the track team. Growing up in Bucks County, Brent lives in Perkasie with his wife, son, daughter, and their Samoyed dog. After training their last dog, (a Keeshond) to be a therapy dog at Children’s Hospital, retirement communities and nursing homes, Shuey (short for Snowshoe) has taken a bit of a different course; he loves to “play” hockey with the kids, and was the inspiration for Brent’s son to take up the sport.
