More to be prized than the lucrative practice with which he has from the start been favored, is the enviable status scientifically of Dr. O. G. Lannon, one of the most progressive representatives of Twentieth Century healing, and in this respect he reflects credit on both the state of his adoption and the city of his birth, Pueblo, Colorado, where he first saw the light on January 9, 1891. He is a son of F. P. and Lucy (Gingell) Lannon, the former a member of the state utility commission of Colorado. Both parents are still living, in the enjoyment of that esteem and good will certain to come to all who faithfully pursue their lines of duty in their day and so work for others of their generation as well as for themselves.
Fortunate in his preparation in the grammar and high schools of Pueblo, Dr. Lannon matriculated at the University of Southern California and from there passed to the Palmer School of Chiropractic at Davenport, Iowa, determined to practice along that ling as his life work. He was duly graduated in 1911 and for five years he practiced where he had been best known, at Pueblo, thus meeting one of the severest and surest tests any man can apply, of starting in his home town. Coming still further west, to California, he opened an office in Fresno and later in Oakland. In 1921 he selected Monterey as the ideal city of residence and professional activity, and here, with well-appointed offices in the Goldstine Building, he has been more than ordinarily successful.
Dr. Lannon was married to Miss Ruth Hitchcock, a native daughter of Tulare, and she shares her husband’s popularity. As for out-of-door life and its peculiar and never-failing attractions, Dr. Lannon likes fishing—far more than the finny fish like the Doctor and his certain casting with the rod. In politics he is a republican. He has become deeply interested in both the city and the county, and city and county are interested, naturally, in him.
