Testimonials

Denver and Aly
Hi Dani, Wanted to reach out and extend a personal thanks for your efforts you put forth in a recent slapping session that my daughter attended at Maninno's Grand Slam in Columbus Ohio this past month. My daughter was very impressed with you. That is the sort of positive impressions that are so critical to developing young girls (2007) as I'm sure you're aware of. We plan to attend additional sessions in January as well and hope to see you there.
