  • I wanted to thank you for your service to Tecmetrics in the recent shareholder buyout negotiations. While we had been unsuccessful on our own for several months, all you were able to rapidly identify the issues that separated us from an agreement, and facilitate a mutually satisfactory transaction. You quickly established a rapport with both parties, and effectively conveyed concerns and issues between us. With your help, we were able to reach an agreement and closing in just 2 weeks. Again, many thanks for your help in bringing this transaction to completion!
