Client Testimonials
" Alain has been serving our company since 2001 as an accountant/bookkeeper in the company's accounting department. His expert and professional advice has been extremely valuable to our company. He is very dependable and works well under pressure. Tax season can be quite a demanding time but Alain has proven over the years how well he works under these conditions. Alain is a very proud family man; he is involved in his community, friendly and highly respected by everyone. We strongly recommend Alain without hesitation. He will be an enormous asset to any business.
