Our History

Liberty Medical was founded in 1990 by Bill Ritter in West Texas.
His vision was to provide O2 dependent travelers with oxygen no matter where they were going or residing at any given time.
Liberty was initially a mail order oxygen company shipping oxygen tanks and home machines to RV travelers and snowbirds to their various residences.
Today the company has expanded to two convenient retail locations in Texas and Colorado and ships nationwide.
  Liberty is owned and operated by the founder’s daughter, Krista Ritter, and her husband, Juan “Tony” Carrasco.
