"They came out in the middle of a storm and promptly hooked the generator to my panel. While I thought I’d be running extension cords to my appliances it turned out that the whole house was up and running. I wish I had done this earlier. I would recommend MGT for any electrical needs. I will surely use them again."

"I highly recommend him for any electrical work! He has completed several projects at my home and has done a phenomenal job every time. He installed recessed lighting in three bedrooms and my bathrooms, as well as completed an outdoor project that required running new electrical wiring. His work is always professional, clean, and done right. He is extremely reliable, responsive, always shows up on time, and is willing to travel wherever the job is. His pricing is also very reasonable and economical for the quality of work he provides. On top of being a great electrician, he is a genuinely great person to work with. I will definitely continue using him for future projects and highly recommend him!"
