Client Testimonials

I just wanted to let you and your staff know how pleased we at GEM Management, Inc. are with the level of service Zeffert & Associates has provided us. Without the great customer service and quick turn-around time provided by you, we would not have been able to meet our deadline. We look forward to doing business with Zeffert & Associates in the future.

-Alex Lawrence, Special Projects Manager

GEM Management, Inc.

As a fully integrated company involved in Multifamily Development, General Contracting, and Property Management, we have had the pleasure and privilege of working with Zeffert & Associates on sundry aspects of our business. Our managers have likewise, attended Zeffert & Associates seminars on Fair Housing and benefited from those as well. We found Zeffert & Associates to be very responsive in meeting the time constraints and quality of work in the Zeffert reports have been, in our opinion, excellent.

It has been great to work with Zeffert for all of our file review needs. They review files in a very timely manner; even though the file reviews are done quickly, the auditors are incredibly thorough and ensure our tenant files are always compliant. Their customer service is top notch. Any time I need assistance, they respond incredibly quickly and get the issue corrected fast. It is a pleasure to work with Zeffert and I hope to continue to do so.

Our first experience with Zeffert & Associates was at a tax credit acquisition/rehab in St. Louis, MO, involving several hundred units. The assistance of their staff was invaluable in getting the certification process of in-place households completed on very aggressive deadlines. The staff is top-notch in their affordable housing knowledge and their willingness to work with the site staff to increase their knowledge is truly remarkable.
