“Professor Ryker’s work with our daughter in college as a private teacher helped create a new confidence in her and took her craft to a whole new level. The growth under his teaching and mentorship was palpable to all who know her. She also grew immensely under his leadership in the opera/musical theatre program, through a variety of musicals, recitals, and cabaret-style performances. We are so grateful for the opportunity for her to work with Andrew.”

— Erin Gorgas (Columbus, OH)

“Andrew ignited that first fire in me as a performer. He laid down a foundation of technique and knowledge that serves me to this day. His support continues to inspire me. A mentor I’m forever grateful for.”

— Stevie LeWarne (Hairspray National Tour)

“Andrew is an incredible teacher and mentor. He has helped to make me a better overall musician, in addition to facilitating my vocal technique, artistry, and repertoire growth. He excels at highlighting a singer’s unique talents and potential, and was an absolute joy to work with throughout my undergrad and graduate work.”
