LICENSES: GAS SERVICE

Having grown up in the family business, Jack officially entered the trades and joined the GSMS team seven years ago because it simply felt like the perfect fit. Guided by the Golden Rule, Jack appreciates the genuine kindness of both his colleagues and his clients, and he wants every customer to know that the team will always try to do their absolute best on every job. A natural learner who loves to master new skills, Jack stays incredibly active outside of work. You can usually find him renovating his first house, woodworking, playing the guitar and drums, or experimenting with new recipes on the grill and smoker. Depending on the season, he also loves skiing or cycling. Above all, he cherishes the time he spends with his fiancé, Hope, and their Australian Shepherd, Norman. Jack is also a proud member of the Pointer Fish & Game Club.

A huge shout out to Jack! Jack is an asset to GSMS family. He was prompt, professional and very thorough with the maintenance of my HVAC system. A bonus is that he was easy to talk to and engaging with conversation about a variety of subjects.

We have been very pleased with GSMS services from replacing our central AC & furnace 2 years ago plus a few plumbing issues we have had repaired and regular maintenance services. Jack, Qwentin, Mark and the rest of the team have been very professional and friendly and do a great job the first time and always cleaned up after themselves. They definitely go above and beyond and we highly recommend GSMS and we do. Fair prices as well!
