Shaun Jay and Greg Paxton are top notch tech! You at GSM truly have a great foundation of technicians and sales men. Very professional and were very good to work with. Also, the ladies in the office have been a pleasure to communicate with; they answered all my questions professionally. Thank you GSM team!

Truly happy with GSM.  From the start GSM sent out an appraiser who took his time and helped work out a plan for me and my budget.  GSM is very flexible with the time I needed for an appointment.

They are prompt, they clean up their miss, you can depend on them and they are always on time.  Keep up the good work.

"Zach was a very respectful gentleman - "yes maam, yes maam", put his shoe covers on & off each time he went in or out of my house.  I was very pleased with his clean up he did when he was finished.  PS. You can't get any better than that. Much happier now that I have someone I can depend on!! Cleaner too!"
