"I now have a beautiful modern condo and I have Leonard Alterio to thank. He was the general contractor for re-designing my condominium from top to bottom. Leonard took ideas I talked about and made them into better realities. Sometimes I questioned his ideas but he would say "trust me" and I always could. Leonard was willing to listen, suggest ideas, and do what needed to be done for a comfortable result. A true gentleman who I can highly recommend."
