Covid19 Update: 
Our team is concerned about your health as well as our own! In an effort to be able to serve you throughout the entire tax season without interruption we will continue to make certain COVID-related changes to our procedures as needed. In Office Meetings: During this tax season you will be able to drop off and pick up documents in the office. We ask that you do not schedule an in-person appointment, unless necessary, to limit our exposure. Options include phone and Zoom meetings. Documents can also be submitted through the link portal, mailed, or faxed. Masks: We ask that anyone who is not vaccinated, or has been recently exposed, wear a mask in our office. Vaccinated people are not required to wear a mask. We will wear masks upon request. Symptoms: If you are experiencing symptoms of COVID, please refrain from visiting our office. We can reschedule your appointment, or make arrangements to meet online or over the phone. Thank you for your cooperation!

Client Testimonials

Working with Chrissy was the smoothest and most pleasant tax experience I’ve ever had. At first I was a bit unsure if it made sense to work with a CPA in PA, given that I live in CA and also have state taxes in another state, but she came highly recommended, so I figured I’d give it a shot–and I am so glad I did! She is responsive, patient, thorough, and lovely to work with throughout.

SAM

It is my pleasure to provide the highest possible recommendation for Chrissy and everyone at CMAG. My wife and I have received the biggest refunds every since switching to CMAG. Furthermore, they are very timely in every respect and Chrissy is always willing to make time for me to discuss tax strategies specific to my situation. I cannot be more pleased with CMAG.

DAN DELCAMPo

I am lucky to have had Chrissy Brennan at Cotton Mather doing my personal taxes for 5+ years. I used to agonize over doing it myself; now I hand everything to her and she takes care of it quickly and efficiently. She even knows if I have missed something and follows up on it. Highly recommend, as long as it doesn’t make her too busy for me!
