“Last night I had the opportunity to talk to a group of students at OSU about my career. Thanks to you and all the things you taught me, I had the confidence to address this crowd of around 100. In the past, I probably would have not accepted the invitation and I am really glad I did. I think you would have gotten a good laugh seeing me practice my exercises in the car ride to Stillwater. Though there is still room for improvement, I was really pleased with my presentation. Thanks again for all your help.”

“I’ve always admired Rena and what she does but it wasn’t until she asked me for feedback on the draft of her book that I realized how incredible and awesome this information really is. I proofread her book, then reread it, then reread it again and took notes. Then I started to do the exercises. This was stuff that I hadn’t been exposed to in Toastmasters. This was gold! Rena taught me that I could actually control the fight or flight reaction by breathing slowly and deeply. Now when I speak I don’t go into fight or flight mode. Recently I participated in a speech contest and am happy to say that I was able to fully express myself, exactly the way I wanted to, without having to battle nerves. Although I was up against some really talented speakers, I did really well!”

“Rena Cook’s presentation to our women’s executive group on how to more effectively use your voice in a commanding way was uplifting as well as informative. Often, it can be difficult for women in business to balance speaking with power and confidence while maintaining approachability. Never a dull moment in her engaging seminar, Rena addresses this issue with a clear expertise. Every woman in the group left feeling empowered to put the techniques that Rena taught into practice immediately.  Her breadth of knowledge on the topic combined with simple, demonstrable techniques to start putting her methods into action made for a powerfully transformative experience.”

“As the former Speaker Pro Tempore of the Oklahoma House of Representatives, I quickly learned my voice had to have authority, but also authenticity, which can be a delicate balance. I am familiar with Rena Cook’s work and its application beyond the theater. The qualities she teaches for the stage are also relevant for business and politics. She offers unique insight for improving communication skills.”

"Rena is a polished, engaging speaker whose expertise on the subject of speech lends her instant credibility. Her presentation gives listeners the tools to speak clearly and confidently in settings large and small."
