Review Image

I’ve been working with Ken and his team for the last twenty five years and they always do such a nice job on our return preparation. The whole office is super committed and helpful. In dealing with the staff I’ve always seen such a high level of commitment from each of their personnel. We’ve used them for dozens of client returns and for complex non filers to catch them up on old returns as well.

Decades of experience with this company. Extremely knowledgeable, dedicated, prompt and personable.  Real winners.

– Margaret Mattson

I have been to several accountants, Ken and Alice are the best in service, knowledge, and giving me peace of mind... I highly recommend them!
