Testimonials
When it comes to broker-dealer platforms for independent dealmakers in the private capital markets, GCS leads by a mile. I’ve taken a close look at all of the major options, and no one else is even in the same zip code, let alone ballpark.

I work on a lot of complex, structured transactions. GCS’s level of knowledge and superior response times makes working as a rep easy. I have never been delayed by an inquiry to the compliance team or given unclear direction on submissions.

In my 33 years as a licensed rep, and having used several different platforms, GCS offers the best platform for their lines of business. Also, the staff is professional, responsive, and efficient. I wish Brian Dunn and his team continued growth and success.

GCS has provided the best broker dealer experience I could have asked for. Having worked at Fortune 500 companies in roles where I frequently dealt with compliance, I can say that GCS’s services are as good or better than any large firm where I spent my prior career.
