Testimonials
"The staff in the Holyoke office have been spectacular! As a former public accountant, I can appreciate the work that they do, and I really can't thank them enough. I would like to specifically point out Jennifer de Warga and Matthew King. Jen has been instrumental in helping my streamline my QBO work and specifically my GL account clean up due my lack of full understanding with QBO. Matt prepared my corporate tax return after working with a CPA that could have done a better job. Matt took on the challenge and got my company back on the right track and I know that going forward I know that he can handle anything thrown his way. Matt also facilitated introductions to other departments such as audit and valuation knowing that I will absolutely need their support as a growing company as well. Having all of these services being provided by a team of knowledgeable staff makes me feel like I really do have a full team behind me."
