Very Polite and Professional and an expert in his electrical field. I had more than three individuals who were licensed Electricians who spent months trying to diagnose my electrical problem which was never solved. Darnell was here less than 15m minutes and diagnosed the problem and after diagnosing , repaired the issue where I was without lights for half of my house since December, 2014.
