Doctor's Message

My life has revolved around sports and injury since an early age. I know the happiness of success and the aches and pains of defeat. I know the satisfaction of what your desired activity brings to you; the feeling of having something you love to do taken away because of injury is so difficult to overcome. It is my greatest honor and what I’ve spend the last decade of my life training to help get you back to what you love to do.
It is a pleasure to meet you, let us get to work

Dr. Tanner Harrah is a Board Eligible Orthopedic Surgeon who is fellowship trained in Sports Medicine and Arthroscopy. He grew up in Temecula, CA, eventually earning a full scholarship in football and competed in track and field at California State University, Sacramento. He obtained a Bachelor of Science degree in Kinesiology with an emphasis in exercise physiology and therapeutic rehabilitation. He then attended medical school at West Virginia school of Osteopathic Medicine in Lewisburg, WV. He went on to complete a 5-year orthopedic surgery residency at Riverside University Health System where he was named Chief Resident and earned Kaiser Riverside Orthopedic Resident of the year. Following the completion of residency, Dr. Harrah spent an additional year to attain specialized fellowship training in sports medicine at the University of Miami in Coral Gables, Florida. During that year he trained in complex knee and shoulder procedures focusing on minimally invasive techniques, arthroscopy, and arthroplasty.

In addition, he was the assistant team physician for the University of Miami football, baseball, men’s/women’s basketball, women’s soccer teams as well as for the Miami Marlins major league baseball team. Dr. Harrah specializes in treating athletes of all ages and abilities focusing on arthroscopic and open surgical techniques.

Dr. Harrah’s general orthopedic practice encompasses virtually all areas of orthopedic surgery including pediatrics, hand, trauma, and joint replacement. He has a specific interest in performing quadricep tendon autograft ACL reconstruction using an “all-side” dual suspensory fixation technique. This minimally invasive surgical approach is new and shows similar outcomes to bone tendon bone reconstruction with less morbidity (less pain, increase strength) in large studies.

Dr. Harrah’s father, Dennis Harrah, played football at the University of Miami earning all-American honors and became a first-round draft choice for the Los Angeles Rams. While playing for the Rams he earned all-pro, 6-time pro bowler and played in Super Bowl XIV.

Dr. Harrah’s brother, Blake Harrah, is a former collegiate football player at Oregon State.

Dr. Harrah’s mother, Teresa Harrah, is a certified personal trainer with 30 years of experience and an avid equestrian rider.

Dr. Harrah enjoys mountain biking, volleyball, running, weightlifting, videogames and spending time with his beautiful wife and daughter, Sayaka and Adah.
