David Pagano is well groomed, has a pleasant, friendly and personal demeanor, professional behavior, well mannered but most importantly an extremely knowledgeable professional.
He was prompt on time to our scheduled appointment which required he make a special effort, after hours, to provide service.
He communicated his findings and options clearly and effectively. His work was efficient and thorough.
He is the service technician for Mauzy CHP&E — formerly Sherlock H&A.
Mauzy should definitely treat him very well, keep him, and promote him as he is an exemplary representative of Mauzy CHP&E.

Another great experience with your plumber Trevor Henry! He did an awesome job on our gas line for the BBQ and now helping us with a leaky shower. Super professional, detail oriented, and helpful in explaining the situation. Please send him back next time!
