Dave, a Chicago native, earned a computer engineering degree from the University of Illinois and engaged in a successful first career in software design and development. A lifelong pianist, Dave began tuning in 1995 as a hobby, but by 1998 his pursuits had grown more serious. He joined the Piano Technicians Guild by way of the very welcoming Chicago Chapter and launched his neighborhood piano service business. Dave earned the Guild's RPT status a year later.
In the course of using the available electronic tuning devices (ETDs) in his work, Dave was confronted with their limitations, and, convinced that the prior methods could be significantly improved, he capitalized on his technology skills and embarked on the development of a successful new tuning device (go to www.veritune.com). Since then he has enjoyed spending the majority of his time supporting and improving the product as well as researching various acoustics topics and related measurement and analysis techniques. At CSPT, he will have the opportunity to pursue other piano-related acoustic research as well.
Dave is a frequent instructor at PTG conventions and seminars, and an active member and past president of the PTG Chicago Chapter. He has been issued three patents, a research grant award, and is a Ph.D. Candidate in Acoustics at Penn State University. Dave is a piano accompanist for various theatre productions and his church choir. He lives with his wife Laura in Chicago where he dabbles in endurance sports with what little free time he has.

Steve joined the Piano Technicians Guild (PTG) in 1978 and attained craftsman level at that time.
Steve worked in Southern California tuning for professional teachers, performers, and several orchestras, including the Long Beach Symphony Orchestra as concert technician from 1985 to 1996, tuning for some of the world's great pianists.
