Justin’s been the best CPA I have ever hired.  He’s very thorough with all the items on your claims and tries his hardest to save you money when reporting your taxes.  He’s a very astute individual who goes beyond his license requirements to keep his knowledge base up-to-date to fight for the highest return on your taxes as possible.

My wife has a hair salon and Justin has been my wife’s CPA preparing tax returns and other govt filings for years. My wife and I file income tax returns jointly so Justin has been preparing them for a few years now. I’m super pleased with Justin’s services.
