"I went to SmartServ Solutions after seeing one of their ads in the newspaper I work for. I was tired of H&R Block and their fast food/hidden and high expenses way of doing taxes. I was looking for someone I could trust and while I was nervous at first, Mario Costanz put me at ease and showed a thoroughness in doing my taxes that I had yet to experience at any other place. Needless to say, I recommended him to my boss and was here to do my taxes again this year. I was scared about my taxes, because I had done some freelance work that I never did before, but once more, Mario helped me figure it all out and I walked away very pleased with my experience. Thank you very much for making tax season less stressful."

My Experience with SmartServ Solutions was Terrific. The professional, courteous staff provide exceptional service.  Appointments are scheduled efficiently and you are not left waiting past your appointment time. I arrived early and was seated in a cozy waiting room with a TV and a restroom. There is even coffee. There was even an area for my 3 yr old to play. Since I have been dong my taxes at SmartServ, it has made a usually dreaded task more bearable. I am now using SmartServ for their other services. They helped boost my Credit score by 30 points!I am VERY comfortable with the Staff and the President of SmartServ and look forward to using them for the purchase of my home.Thank You SmartServ!"

Complex Technologies

"Great and honest guy. If he can help you, he will surely let you know. If he can't he'll be sure to let you know too. My first experience was a good one. I came to SmartServ in need of a mortgage and when it couldn't be done, I was told so. When I referred SmartServ to a friend in need of credit repair, they gave the advice and told my friend they could handle it easily on their own. Not everything is free, but it's not everywhere you go that you can find good advice, honesty, and great service. Will do business again and again."
