I have had the pleasure of knowing Mark Keffer for the past 10 years. Mark is very hardworking and is a true perfectionist. He pays attention to every detail and makes sure things are done right. He is a strong believer in using quality products to get the best outcome.

I would describe Mark as very trustworthy, as I have given him a key to my house on several occasions to complete a project. I have also liked that he always takes the time to explain what needs to be done and how he will accomplish the task at hand.

I would highly recommend Mark and think you will be very pleased and impressed with him.
