Tremble Clefs Arizona is a non-profit 501 (c)(3) Charity
Don Dotts graduated from Arizona State University and then joined the staff as Alumni Editor. Later he became Executive Director of the ASU Alumni Association, a position he held for 26 years. He spent 42 years on the ASU’s administrative staff. Retired, Don is president of Tremble Clefs Arizona and chairman of the Original Tremble Clefs. He is also on the Board of the Parkinson's Network of Arizona and serves on 5 other non-profit boards in Arizona.
Don’s late wife, Annis, had Parkinson’s disease. They joined Tremble Clefs 20 years ago. Annis had been a music teacher and she really enjoyed Tremble Clefs. Mr. Dotts was amazed at the wonderful effect TC's music therapy had on people with Parkinson’s. When she passed away 9 years ago, he decided that he had to remain involved to help keep this wonderful program thriving.
Born and raised in southern Colorado, he ventured along several pathways before settling on a career with Arizona State Government; the last 21 years as the Ombudsman/Problem Resolution Officer for the Arizona Department of Revenue. He retired six months after being diagnosed with Parkinson’s Disease (12 years ago). He joined the Westside Tremble Clef’s four years later and currently serves as Vice President of this group and of Tremble Clef’s Arizona, our 501 C3 umbrella organization overseeing the current three (soon to be 4) active choirs in the greater Phoenix area. John is convinced that singing enables those with Parkinson’s to have a voice for a much longer time than those with PD who don’t exercise their voices and, as such, enjoy a better quality of life. I invite all individuals with PD to find a choir to join and help us to make a joyful noise together.

When Al was diagnosed with Parkinson’s in 2004, they immediately shared with family and friends and learned as much as they could about the disease. After their move to Arizona, they were directed by staff at the Ali Center to the Scottsdale Tremble Clefs. That was in 2009. From the beginning they developed friendships and were active in the group. Having experienced the positive difference Tremble Clefs made to their lives, Donna, a widow, continues her support of Tremble Clefs Arizona.

Dan, who had Parkinson’s disease, was an active member, a leader, in Tremble Clefs. Sun Joo Lee, our music director, remembers Dan always arrived early at the West Side Tremble Clefs to help with set-up and see how he could help her get ready for the practice sessions.
He served as Treasurer for the West Side Tremble Clefs. Mr. Jilka responded “yes” to a request to serve on the Board of Tremble Clefs Arizona.
