They bring a great deal of energy and enthusiasm to any performance. I wouldn't think of a season without their being headliners. - Phil Chilcote, Sidney Civic Band Conductor

Great expectations...Great Expectations more than met! I had a lot of great comments about Simple Harmony's Entertainment, and they should get a good following from this. I did not want the entertainment to end, but how beautifully it ended by singing a request and their arrangement of our theme, "When You Wish Upon a Star"...That was going "the extra mile" to accommodate the event. Thank you so much. This group is amiable, professional, and in perfect harmony! - Petra Sengsy, Volunteer Coordinator Hospice of Miami County, Inc.

We conclude this is one of the best vocal ensembles now performing anywhere in southwest Ohio... - William Berry, New Carlisle Chautaqua Arts

"...the blend and balance was beautiful." - Jim McCutcheon - Dayton Art Institute
