Besides everyone being helpful, warm and friendly I know I can call at any time and someone will help me. Also everyone is professional and up to date on all the tax rules. The best thing that happened to me when was when I was recommended to the Leonard Tam team.

Exceptional communication, extremely professional and amazing service. When they met with me, they were very organized and efficient.
