TESTIMONIALS

Colleen is an amazing tax specialist. I can't tell you enough about her ability to work through complicated situations with our family's income and make sense of it all. Instead of paying every year, she uses her knowledge of tax law to help us come out ahead of the game. Colleen's our savior each and every April 15!

What can I say about CMDT and Colleen McDermott? Well, I have to say that she's wicked smart and that she really takes the time to get things right. I've been working with her for 20 years and she has always been a great communicator and one whose attention to detail is outstanding.

Colleen practically runs my business from her office in Tewksbury. She keeps my books balanced and help to get our payroll perfect for my small group of employees. Her guidance with our quarterly tax payments is also well appreciated.
