“Kimberly Kosmenko is a phenomenal public speaking coach. She helped me prepare to give a talk in front of a larger audience than I ever had before. We worked together to nail down my content, identify and improve my delivery and presentation, and focus on how to stay ‘in the relaxation zone’ before and during my talk.
