Best experience I’ve ever had in a doctor’s office! Easy to make an appointment and the office staff were outstanding, especially Melissa. X-rays only took minutes and we didn’t have to wait at all to see the doctor. We came in for a follow-up consult on my daughter’s leg and we were in and out in no time with exceptional medical knowledge and advice. Doctor Lyle Rosenfield exceeded all expectations. Look no further – this is the best orthopedic office in San Diego County!
