I have used DM&M since 2009 to complete personal, business, and family trust tax returns. Senior Accountant Tim Myett [...] has expertly completed my returns and provided excellent tax advice. I have been very pleased with the professionalism of Tim and DM&M and highly recommend them.

Chris is the only CPA who responded to my inquiry within 24 hours. Uploading documents into the portal was a breeze, and our tax return was completed within two weeks. I’ll never go back to doing our taxes with other online DIY programs - you get what you pay for!
