Advanced Orthogonal

Advanced Orthogonal (ADVO), the byproduct of research of its founder, Dr Stan Pierce of St. Petersburg, FL is a very similar, precise variation of the Atlas Orthogonal (AO)Procedure that modifies some of the original xray measurements and mathematical formulas used in calculating adjusting vectors, as well as some patient setups originally created by Dr Sweat in Atlanta, GA.    Dr Dolan has studied extensively under both instructors and is indebted to each for enabling him to make the most accurate, effective upper cervical  corrections possible.
