Our Audit Staff

All of our staff have in excess of ten years experience in their respective areas, including specialized not-for-profit training, and have been subjected to our extensive qualification and orientation programs designed to support delivery of high-quality and congenial services.

Our philosophy is that clients are not well served by using junior auditors-in-training. Our experience has been that while fees for such persons are relatively inexpensive, their lesser experience may not optimize the quality of the audit or provide the most effective constructive services to our client.
