Is there anyone in the southern California area who services/works on deardorffs?

if not does anyone know if Ken Hough is still doing repairs? his website doesn't look to have been updated since 2010

I have R.R.'s info and have used him successfully in the past, just wondered if there was anyone closer who specialized in Deardorffs...

I need something tweaked and can't wait a month for it to get done.
