"Anthony was hired through Angie's List handyman services. I contacted Anthony a few days before the expiration date on the deal. We were not able to schedule a date to do the work at a time convenient for both of us. Anthony assured me he would do the work even though it would be after the expiration date. I always received a call back whenever I needed to contact Anthony He did excellent work on all the jobs, and made suggestions that avoided extra expense. He worked until the job was done and did not worry about the time. He returned to replace a ceiling fan bowl that was broken. I was impressed with his knowledge and professionalism and the quality of his work. I would not hesitate to hire him again."
