Client Testimony

I first went to Debbie after I received a huge tax bill. Debbie refiled 10 years of tax returns and solved my problem. I not only have full confidence in her, but also enjoy her sense of humour and the warm atmosphere in her office. If you’re looking for a person
who is passionate about her work, I’d highly recommend Debbie Sitzer Professional Corp. I won’t use anyone else!

I live in London now but still use Debbie Sitzer Professional Corp. Debbie is direct, extremely skilled, and has a refreshing sense of humour that’s rare for CAs. She has championed my cause with the CRA and makes sure I get every dime to which I’m

Debbie Sitzer was the first accountant who really worked for us. She was completely dedicated to helping us and was fearless in dealing with Revenue Canada. I recommend her to anyone looking for personalized and personable service.
