To whom it may concern, Dr. Alfredo Guevara Jr. MD is the kindest,concerned,professional, friendly, considerate, obliging, PERSON I have ever met.. Wish I had known him 30 years ago !! He resolved my case, from the first time I met him and his equally proficient team.. I had experienced a (Nearly) SCAM by a Dr. in Mexico where I was being treated, So I searched and decided to go to Arizona, USA for diagnosis and treatment. I could NOT have made a better choice !! Even tho' it entails a 13 Hour round trip, by bus..I might add the bus service by "TUFESA" is excellent in Mexico... Thanks , I highly recommend this outstanding Man & Doctor !!!!....PS-His NEW address is 507 North Western Ave.-- Same city-Zip-Phone.
