The Lady Meets a Maverick

Then, one never to be forgotten day Olive became acquainted with Hugh Riordan, M.D. Dr. Hugh D. Riordan had also been interested in nutritional medicine ever since his medical school days when he had been given a rat that had been deprived of only one nutrient. He watched as his rat (deprived of selenium) slowly became weaker and it’s coat lost its gloss. When they reintroduced the missing element into the rat’s diet, it quickly regained its health and stamina. Some of the other students’ rats died when deprived of their particular nutrient.

The rat study made an impression on soon-to-be Dr. Riordan. Also after completing his internship he was associated with Dr. Fowler Poling who used vitamin B in treating mental problems. Dr. Riordan also was a consultant at Sunflower Mental Health Center at Concordia, Kansas. The director, Jon Sward, had arranged for Dr. Riordan to attend a medical conference in Canada on Orthomolecular medicine. Ortho means something that is found naturally in the body and molecular means in small amounts. Orthomolecular medicine means to use small amounts of a naturally occurring substance in the body to treat illness. At this meeting Hugh became acquainted with Carl Pfeiffer, M.D., Ph.D., who had founded the Brain Bio-Center in New Jersey. At Pfeiffer’s center they treated schizophrenia by measuring certain elements in the patient’s blood. They found that by using nutrients to change those readings they could change the course of schizophrenia.

Later on Dr. Pfeiffer was invited to Wichita to do a lecture on the methods used at Brain Bio-Center. Bill Schul attended the lecture, as he was still interested in alternative medicine. Bill Schul and Dr. Riordan knew each other from meetings that were held at Council Grove, Kansas, investigating various forms of phenomena.

After the lecture, Bill invited doctors Pfeiffer and Riordan to meet Clifford Allison, a lawyer and executive director of the Garvey Foundation. After meeting with Cliff Allison and visiting about the Brain Bio-Center, Cliff asked them if they would like to meet Olive Garvey. After talking with Mrs. Garvey for a few minutes, Dr. Pfeiffer told Mrs. Garvey that she should give Dr. Riordan the money to set up a laboratory in Wichita like the one he had in New Jersey. About a week after the meeting, Mrs. Garvey asked Dr. Riordan to write a grant to set up this laboratory. First, Dr. Riordan had to call Dr. Pfeiffer to find out what kind of lab he thought Dr. Riordan should set up. Dr. Riordan had written many grants over the years and knew how unlikely it was to be given this grant, especially since he had read Mrs. Garvey’s book Produce or Starve. In that book she had stated that you should never trust a man with a beard. Dr. Riordan had a beard so he did not think she would seriously consider his proposal. He spent very little time on a handwritten grant that basically said, “I don’t know what I will do and you don’t know what I will do but I will spend the next three years doing it.”

Hugh D. Riordan was the perfect man for the job. He had a healthy self-esteem and liked to swim against public opinion. His personal life also recommended him for this job. He was born to parents who had cosmopolitan flair. His mother was of Russian and French ancestry and as a 17-year-old had fled from Russia in a cattle car during the Bolshevik Revolution in 1918. Tatiana Alexandropol eventually made her way to Japan where she taught French, having spent one year at the Sorbonne before the revolution. There she met Hugh Riordan, a young economics professor who was the next to the youngest in an Irish Catholic family with 14 children. After they both survived a major earthquake they traveled to America via Nice, France, where they were married. Hugh returned to Milwaukee with his bride and became a professor of Economics at Marquette University. Two sons were born to them, Lee and seven years later Hugh Desaix. Tatiana was almost 34 when Hugh D. was born and his father was 39.

Family Circumstances Influences Future Choices

Hugh D. did not start formal education until he was seven and has said many times that he believed that he had developed a strong self-reliance before entering formal education. His family lived in a three-bedroom apartment house, which also had a pantry. One end of the pantry was his workshop and housed a crystal radio. Hugh D. was always interested in electrical engineering and thought he would become an electrical engineer someday. But an illness contracted by his older brother, Lee, piqued his interest in the field of medicine, or at least contributed toward it. Lee had been ill for several weeks with a throat infection that doctors could not seem to cure. One day his father read a report about sulfa and asked the doctors to try this “new” medicine on Lee. They were willing to do so and in three days he was on his way to a complete recovery. Later, Hugh D. found that sulfa had been around for several years – the doctors just did not know about it. He learned two things from this experience that would help him in the future. One, that you cannot always rely on the “experts” to know everything. Two, it sometimes takes many years from the time of the development of something new to the acceptance and usage by the scientific community.

Hugh D. had a fairly normal but enriched childhood. He walked 1.5 miles to school in the morning, walked home for lunch, back to school after lunch, and then walked back home at night. The neighborhood was safe back then; he and Lee were allowed to roam around without strict supervision. He was able to investigate his environment, developed a sense of adventure, and learned to be self-reliant. He was allowed to make mistakes and learn the consequences of his actions.

Politics also had its beginnings in childhood. Hugh’s first campaign for office was in high school when he ran for Prom King. Watching Dr. Riordan relate this experience you can tell that he enjoyed the creation and production of the campaign. Needless to say, he won Prom King. Later, he was to use those same skills in working for a governotorial election. He has always been a keen observer of the political system and this would be important in running a medical center.

Hugh D. Riordan was a good student in high school and won a scholarship to Harvard. Since his father was a professor at Marquette he could have gone to college at Marquette University with free tuition. Again he chose a road less traveled. He opted to work for a year before he went to college. He obtained a job at IBM and learned about corporate America, which included singing “Good Morning to You” to the CEO, Mr. Thomas Watson. One year was enough to show him that while he learned a lot, and enjoyed the experience, that wasn’t the way that he wanted to make a living. He decided to go to the University of Wisconsin in Milwaukee and major in medicine. Today he cannot answer exactly why he chose medicine rather than electrical engineering. The most likely explanation was the experience involving his older brother.

For Hugh D. working his way through college was enjoyable, as was college itself. During that time he worked for Bjorsten Foundation. Hugh D. was the night watchman and was supposed to check in every hour. One time he missed calling in at the regular time and the police arrived with drawn guns to find him asleep on Dr. Bjorsten’s desk. His boss told him that he might want to get caught up on his sleep elsewhere. He never missed calling in again.

Wichita – The Beginning of a Professional Career

When it was time to look for a place to do an internship Dr. Riordan again went about finding that place by researching the various programs. Dr. Riordan and two buddies wrote several hospitals asking questions about their programs. Saint Francis Hospital in Wichita, Kansas, was the only response to their many letters that told them about the program and the city of Wichita. The three decided to do their internship in Wichita. At the time they applied, Saint Francis had the largest psychiatric unit west of the Mississippi. While at Saint Francis Dr. Riordan enjoyed his work but especially enjoyed the drama of the emergency room. The interns from Wisconsin were popular because they were so well trained. When the internship was completed, Dr. Fowler Poling asked Dr. Riordan to come to work with him. Back then you could either complete a residency after internship or practice under another doctor for a period of time. Dr. Riordan asked his former advisor what he should do and his advisor told him if someone was willing to pay him to learn more to jump at the chance. So Dr. Riordan began to work primarily with mentally ill patients. He remembers one patient whom he was trying to convince to go to the hospital but he could not persuade her to go. Dr. Poling came in and observed for a while then said, “My dear, he is telling you that you are crazy” and she replied, “Well, why didn’t he say that?” She went to the hospital without further delay. Dr. Riordan learned the value of plain talking when necessary.

Working with Dr. Poling gave Dr. Riordan another chance to further his powers of observation and listening skills. Poling was ahead of his time, using the B vitamins to help people with mental problems. After being there for several years, Dr. Poling and Riordan met one night to plan for the next five years. Dr. Poling had always wanted to be a pilot but his family thought it was too dangerous. Dr. Poling decided that night that he would learn to fly. A couple of days later he was dead from an automobile accident. This had a profound effect on Dr. Riordan and he decided at that time he would not do the same thing for more than six years. Life was too short and uncertain to do the same thing day after day. Dr. Riordan had a small business, Psychic, Inc., in the basement of the same building where Dr. Poling’s practice was located. Dr. Riordan did consulting with the school system. After Poling’s death Dr. Riordan was given the option to take over Poling’s business but declined because he felt the conditions were unacceptable.

Later he developed a large practice. In 1967 he concluded that he was not enjoying the practice as much as he had in the past because he was spending most of his time doing administrative type work.

About the time Mrs. Garvey requested Dr. Riordan write a grant to establish a research laboratory he was ready to try something different. He knew that nutrition had been helpful in treating some patients, that psychotherapy was a lucrative field, but he was not as certain that it was all that beneficial, and he was willing to learn more about it, depending on the slim chance that the Garvey Foundation was willing to give him a grant. He did not know that Mrs. Garvey was waiting for someone with his ability, confidence, and strength to share her vision of using nutrition to improve health.

The Center

In 1975 Dr. Riordan founded The Center for the Improvement of Human Functioning International Inc. with benefactor Olive W. Garvey. In 2010 the name was changed to the Riordan Clinic. The Riordan Clinic was founded on the principal of biochemical individuality. Blood based nutrient testing, combined with intuitive diagnostic skills, allowed Dr. Riordan and the Riordan Clinic staff to provide help and hope to people from around the world.

In an unpublished manuscript written by Dr. Riordan he said, “For the largest part of my career, I have been engaged in serving people in ways which allow them to restore their health and hope through sensible and sensitive exploration of their own one-of-a-kind physical systems.” The unwavering belief in treating the whole person, to get to the root cause of a problem, continues to be a primary factor in the Riordan Clinic’s success.

The most notable body of work from Dr. Riordan is regarding mega doses of vitamins, specifically vitamin C (50 grams and higher), and the positive effect it has on many chronic illnesses. Dr. Riordan’s vitamin C protocol was developed in part based on the findings of Linus Pauling. Riordan was a follower of noted Nobel Prize winning chemist.

Dr. Riordan was the author of four books, three of which deal with topic of “Medical Mavericks,” a topic which interested the doctor as he was a maverick when it came to nutrition and medicine. He also authored more than 79 medical journal articles and papers, many of which were published in peer reviewed journals. The vast majority of his papers dealt with the benefits of vitamin C. Dr. Riordan was a prolific speaker with more than 186 public speaking engagements from 1979 – 2004. His legacy continues today at the Riordan Clinic in Wichita, KS.
