He was the third member to join after frontman Elijah Blue Allman sent him a Juno-106 synth and a demo tape made by Allman and drummer Alec Puro. About joining Deadsy, Hawkey said, "I never planned on it until Elijah sent me a Juno-106 in 1996 and asked me to join a band with two songs."
On September 11, 2008, Dr. Nner apparently left the band in order to concentrate on carpentry and family life. "It was too rough-and-tumble a lifestyle," said the man who has become Renn Hawkey again, full time.
He is married to actress Vera Farmiga, with whom he has a son, born January 15, 2009. It was announced in April 2010 Hawkey and Farmiga were expecting their second child, due in October. On November 4, 2010, Farmiga gave birth to a daughter.
