I have not seen Dr. Howard as a patient. I'm lucky to be married to a massage therapist who takes good care of me so I rarely need chiro care. I'm not personally convinced in upper cervical chiro, but I've talked with others that swear by it. I have known Dr. Howard's wife for years and they're good people. I believe they have information about upper cervical chiro (tapes, etc.) that you could get to answer your questions prior to scheduling an appointment. I've only heard of Dr. Pierce's name but don't really know anything about him. Good luck in your quest for good health!
