Dr. Kris Oka is a dentist from San Francisco. He has had a lengthy interest in the steel guitar and in 2017 began training on the steel guitar with Alan Akaka. He made his public performance debut on last year's Hawai'i Island Steel Guitar Festival's open stage and also performed on the 2018 Maui Steel Guitar Festival's open stage.
The steel guitar Kris is using is manufactured by MSA Steel Guitars in Dallas, Texas. Bobby Ingano was so impressed by Kris' guitar at last year's Hawai'i Island festival that Bobby had a custom 7-string MSA lap steel guitar manufactured especially for him.
