"He was passionate about it and loved to do it," said Hardy's friend, Dr. Andrew Lynch.
Lynch said Hardy, 34, was a fun-loving guy with a genuine smile, and a person you couldn't help but like.
Hardy died Friday in a skiing accident on Mount Baker. He had just summited the mountain with his friends and was skiing down when he accidentally went over a cliff at the 9,000-foot level.
Hardy's colleagues say his passion for sports carried over into his medical career. Just a few weeks ago he was a presenter at a national conference on sports medicine.
"He should be remembered from a professional standpoint as a great doctor and a rising star in our field, because he was," said Lynch.
According to his clinic biography, Hardy was also the team physician for the University of Washington lacrosse team and the Sammamish High School football team.
"We are deeply grieved by our loss," Hardy's family said in a written statement. "Keith was a wonderful husband, father, physician, and friend. He lived his life with purpose and passion. We know all those whose lives he touched will miss him dearly."
On Saturday, a Bellingham Search and Rescue team attempted to climb to the area where Hardy's body was found, but because of weather had to turn back at the 7,700 foot level.
The search crew is now waiting for weather conditions to improve before making another recovery attempt.
