Dr. Guillermo Valenzuela: Truffle Hunter, Tennis Player, Motorcycle Tourist

Some would call Guillermo J. Valenzuela, MD, a hunter of sorts. He has accompanied men and their dogs into the forests of Italy in search of white truffles, an underground fungus considered a European delicacy.

“Years ago, when visiting my wife’s family in Italy, I walked into a very old restaurant in Parma,” says Dr. Valenzuela, director of both Integral Rheumatology & Immunology Specialists and IRIS Research and Development, which supports two Florida offices in Key Biscayne and Plantation. “I smelled the pungent scent of white truffles and was totally inebriated.”

Since then, Dr. Valenzuela has become obsessed with the white fungus and impressed by the relationships between the hunters and their dogs, which are trained to sniff out truffles. He says the dogs can easily cost 30,000 euros (almost $34,000 U.S. dollars).

“Men walk in the forest and give their dog verbal commands that make the dog anxious to find the truffles,” he says, adding that truffles only grow wild and resist being planted or cultivated by anyone other than Mother Nature. “When they find them, both are in such joy. It’s something very nice to witness.”

Unfortunately, he only eats truffles when he, his wife and three children travel to Italy every Christmas to visit family. His father-in-law, a foodie, ensures truffles are always on the household menu.

“The truffles are cut into thin slices and served on top of a pasta dish with butter and Parmesan cheese or on top of scrambled eggs, which is a must,” Dr. Valenzuela says.

At roughly $200 an ounce, packaged truffles aren’t cheap and don’t compare with fresh truffles.

Hunting truffles is just one of the rheuma­tologist’s interests. He also plays tennis twice a week, sometimes with a friend who’s a Wimbledon tennis champion, and spends roughly two weeks every year riding a motorcycle in different countries. He says these combined activities help him enjoy his life as a physician, husband and father.

Initially, Dr. Valenzuela hoped to practice aerospace medicine, an offshoot of his father’s career as an aerospace engineer in Argentina. In 1986, he graduated medical school from the University of Buenos Aires in Argentina, but then opted to complete his training in the U.S. From 1988–91, he completed his internship at New York Medical College, finished his residency at the same school in 1992 and then completed his post-doctoral fellowship at North Shore University Hospital, affiliated with Weill Cornell Medicine at Cornell University, New York.

During his residency, he met John Zabriskie, MD, who special­ized in infectious disease. “After multiple discussions and games of tennis, Dr. Zabriskie inspired me with his beautiful, challenging picture about rheumatology and immunology,” says Dr. Valenzuela, adding that Dr. Zabriskie became his mentor. “I fell in love with his view about rheuma­tology and immunology, and was very moved by his research on rheumatic fever. He helped me become who I am today.” (Dr. Zabriskie later became an emeritus faculty member at The Rockefeller University in New York and died in 2017.)

Dr. Valenzuela has played tennis since he was a child. He competed in the junior division and recalls sneaking out of his house at night to watch his idol, Guillermo Vilas, train at a nearby sports club. The former professional tennis player won many championship events, including four Grand Slam tournaments and nine Grand Prix Super Series titles. Over the years, the pair have become good friends.

After graduating medical school, Dr. Valenzuela spent nearly a year traveling and playing tournaments in Europe. Back in the U.S., he played in tennis tournaments sanctioned by the International Tennis Federation, played on the tennis team at North Shore/Cornell, won small events and coached tennis students.

“I’m fortunate to have met people throughout my life who became professional tennis players,” says Dr. Valenzuela, adding that one of his friends—Jean-Julien Rojer—won the men’s double titles in 2015 Wimbledon and the 2017 U.S. Open. Dr. Valenzuela says he can still “keep the ball in play” with them or play at their pace.
