Client Testimonials

  • Peter handled our return quickly and professionally despite relatively short timeframes and my unfamiliarity with the documents needed to do so. He did a great job for new clients and I have already recommended him to several neighbors.

  • Peter McDonald is by far one of the most professional and conscientious advisors I have on my personal and business financial team. He explains things in a way that is understandable to those of us non-accountants, and is extremely knowledgeable on both my individual financial/tax issues as well as my previous company.
