Dr. Assil is the most wonderful, patient and compassionate doctors I have ever met!! He cares deeply for his patients and really tries to get to the root of pain. However, his staff is incredibly rude and have been so horrible on the phone with me multiple times. Both his surgery scheduler and his LVN. I’ve debated going to another doctor because of his staff but I appreciate his care so much.
