Peter and his team have helped me streamline my business. Instead of spending hours each week worrying about payroll and taxes, I can instead focus on what I do best, and have grown my business substantially.

When it came time to open my practice I went looking for an accountant that would help me avoid major pitfalls and unnecessary expenses while I focused on growing my business. In choosing Peter McMahon I have found a team that is responsive and attentive, forward thinking and focused on tax planning each year as it develops. That has provided me with peace of mind and the time and energy to focus on my clients instead of worrying about tax issues. I feel like choosing Peter’s team has been one of the smartest decisions I’ve made as a business owner.
