He enrolled in the Palmer School of Chiropractic, Davenport, Iowa. In addition to the regular course of studies, he taught in the College and while there he received special instruction from D.D. Palmer. He graduated in 1912 and returned to his home town, Scott City, Kansas to practice his chosen profession. Early in his practice he was influential in getting a law passed in Kansas to license the Chiropractic practitioner. Kansas was one of the first states to pass a Chiropractic Law and this law was free of Basic-Science requirements for many years.
In 1919 Dr. Drain and family moved to San Antonio, Texas where he later became President of the Texas Chiropractic College in association with Dr. H. E. Weiser and Dr. C. B. Lofting. They were partners for thirty-four years.
Besides his duties as Executive, teacher and practitioner, he traveled over the entire State of Texas and parts of Louisiana, (for the most part of his own expense). He felt it was his duty to help wherever he could to defend the Chiropractors against the erroneous charges of “practicing medicine without a license."
Dr. Drain was the expert witness in many of these cases and in a test case in which Dr. A. E. Brammer of Bandera, Texas was charged on 23 counts of the same old charge “practicing medicine without a license.” He contacted Mr. E. B. Simmons and they together went to help Dr. Brammer. Mr. Simmons was instructed in the technique of defense and later became famous on a National level. The “Judge” as he was affectionately called, when speaking to Chiropractic Groups never failed to express thanks to Dr. Drain for the invaluable training he received in this matter. The technique was so successful that no cases were lost.
Only once was Dr. Drain put in jail. The circumstances were: he was appearing as an expert witness in this particular case in Columbus, Texas and the feeling was running pretty high. He was held in jail over night for his own protection. One time a ridiculous charge was made against him which was intended to embarrass him professionally but was thrown out of court as the charge was – he was “about to practice medicine without a license."
Although he taught many technical subjects, “Chiropractic Philosophy” was his favorite. This is evidenced by his writing which include two editions of Chiropractic Thoughts and his latest effort Man Tomorrow both of which were standard texts in the Texas Chiropractic College at one time.
Dr. Drain was known as a dynamic speaker all over the United States. He was a member of the Texas Chiropractic Association for many years. Due to his enthusiasm and success, nine members of this family became chiropractors.
He was a member o the Presbyterian Church, also a member of the Bluebonnet Masonic Lodge in San Antonio and the Scottish Rite of Salina, Kansas. He was always ready to encourage and help a student or a Doctor of Chiropractic; in some instances financially. Some were grateful and some were not but he was not bitter nor discouraged.
After retiring from the Texas Chiropractic College he established a beautiful, fully equipped Chiropractic Clinic at 111 Highland Boulevard, San Antonio, Texas. In 1951 he received the Keeler Plaque for outstanding achievements, of which he was very proud. He was still in practice when he died of a Cerebral Hemorrhage, February 27, 1958.
