We've used D&M Accounting for the past several years, through both work and retirement years. They've not only saved us money year after year, they've done it with courtesy, care, and accuracy. When we moved to the East Coast for three years, we continued to use D&M services, and it was a better decision than the one we made to move East! We can't say enough good things about the entire staff there.

D&M has friendly staff and affordable services. I have total confidence in their accuracy and knowing I'm getting the best return possible at tax time. The help I received in setting up my small business took the guess work out of it and let me focus on the creative side of my work. Thank you D&M!

Look out. If they make mistakes, you get the blame. Did use them for years, and things we're okay. But then discovered some bigger errors in the past year, tried to work through it with them, and I got the blame for it. And these were sloppy errors too. They probably offer good service on the whole, but not in my case. Will likely get about $4600 back from the IRS when they're fixed.

I can't get into great detail but all I can say is great service. Connie has been doing my taxes for years and she is always willing to answer any questions any time and that includes during some of the busiest times of the year. It's great having a piece of mind knowing your personal taxes are in good hands.

I've been using D&M Accounting for years now and am a very satisfied client. Extremely prompt responses to calls/emails, fast and accurate turn-around with my taxes. Couldn't ask for more.

Connie and her staff have been doing my taxes since 1995! Connie herself, has gone above and beyond more than once to take care of some "delicate" tax issues that I have faced after the loss of my Dad and then several years later the loss of my Mom. Words can't express how much I appreciate Connie, and her staff!

Love the staff and environment at D&M Accounting. They always take the time and do things right the first time and do a great job of working with you to get what they need and keep you in the loop. The owner is the kindest person you will meet and your experience will be nothing but the best!
