Valentin: this is Tracy aka Marilyn. This was my first experience with Valentin/Strong Plumbing Inc., and it was great right from the start. I appreciate Valentin's quick response to my initial email, and his follow-through right to giving me an estimated cost and his time of arrival. He arrived, this morning, when he said he would, in fact he was 5 minutes early. He replaced the kitchen sink pipes, checked my bathroom sink pipes, cleaned out a bathroom drain for me, and all the while he was very knowledgeable, pleasant and friendly. If only everyone who works with the public was as customer service oriented as Valentin. The next time I need a plumber, I'll know who to call. Short story: he was great.
