What our clients say.

Working with Cothran Development Strategies on our biennial gala is a joy. We have confidence that all of the details will be handled and that it will be a truly special event. Also, they are skilled fundraisers and have helped us increase our net proceeds with each event, which has a direct, positive impact on the center’s ability to achieve its mission.

Since working with CDS in 2012, I--as a board member of The Association of Trust Organizations, have found them to be attentive, engaged, timely, thorough, easy to work with and consummate professionals. My only reluctance in going on the record is that I'd prefer they remain our
little secret...

I can't be more proud of the work CDS has done for our organization. They put together probably the most organized Convention that we have ever had and I have received A LOT of compliments! CDS helped take our organization to the next level in a short amount of time.


Chad Selman

Utilizing CDS' complete management services has made a huge positive impact on our association. Not only have we seen our budget numbers and event attendance increase, but the level of membership and administrative services has been significantly higher and beneficial to our entire organization.

Many years ago when I was the Chairman of the National Stripper Well Association, our board was interested in expanding our membership to other producing states and having significant improvement in business office support services. We hired Cothran Development Strategies and the NSWA has never been better served.
