Review for Dr. Crall

Dr. Thunder was recommended by several people I know, including people in the medical field plus former patients who received full knee replacements. My surgery was well planned and performed. Through Dr. Thunder, I am doing follow-up PT at Torrey Pines Orthopedic Medical Group.

Review for Dr. Richardson

Dr. Brown was great but his front desk person is awful and should be fired. I was supposed to come back for another injection in my hand and she made sure I didn’t. I gave up after a year of trying. She’s horrible.
