Real Clients. Honest Feedback.

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.

Great app they use for filing the taxes its nice that everything that was documented year prior is there, things i would suggest to add would be a part of the app that you can pay your dues through and then maybe get an update when they have completed and filed with the irs so that your aware of the status of completion overall great buisness Mr. Deblanc is very professional and dedicated as well as being a decorated motivated US Marine he will accomplish his mission for you and that is quality service highly recommend this Buisness for your taxes top notch thanks again.

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!
