He was showed up on time and very knowledgeable about installing a washer & dryer. He was also installed a thermostat as well.

I hired Sergio based on a on NextDoor recommendation. He is a state licensed electrician who has previously done work for contractors. He came out the same day to give an estimate and was able to do the work the next day. His rates are reasonable and he uses high quality materials. I was very happy with the work that was done. Our bathroom socket is finally up to code with a GFCI circuit. Thanks Sergio!
