Dr. Krongrad joined his first house call when he was six years old. In a time before deductibles, that early morning adventure imparted a lesson: being a doctor means getting out of bed and doing something.

In his nearly 60 years with patients, Dr. Krongrad has delivered babies in a remote Africa; attended a nutrition clinic, a diabetic wound clinic, and a hypertension clinic; treated gun shots in the inner city; co-authored the first human clinical trial ever to show cancer prevention with a dietary supplement; cloned the rabbit androgen receptor; and introduced laparoscopic prostate surgery to the United States.

His grandmother farmed chickens, his parents farmed dairy cows, and he grew radishes and onions in Brooklyn. He has stories about tractors and barns.

Dr. Krongrad was a competitive swimmer. He exercises daily, with an emphasis on resistance training, running, ju jitsu, swimming, and some crazy stair hopping. He's grappled in the Amazon and swum Tampa Bay in winter to raise money for military orphans. Once, because he made a promise to a friend, he ran the Boston marathon with a broken foot and finished.

Catch Dr. Krongrad at the office and he'll give you an earful on how the blind Somalian cavefish entrain their circadian rhythms without light and and wonder our loud why the tribesmen of Baluchistan, who don't eat vegetables, don't have scurvy.

He's a cook and, if you ask nicely, he'll share which kind of butter he favors. In the old days, he was a jazz musician who also played on a pop tune that went to number one on the charts. He's the man who killed disco.

Arnon has a batchelor's degree in chemistry from Columbia College. He became a doctor after graduating from the College of Physicians & Surgeons of Columbia University in New York. Dr. Krongrad completed a surgical internship at the University of Hawaii and a urology residency at the Mount Sinai Medical Center in New York. He was the Dornier Scholar of the American Foundation for Urological Diseases and completed a basic research fellowship at the University of Texas Southwestern Medical Center in Dallas.

Dr. Krongrad is not a nutritionist or strength coach. He doesn't run a sleep lab. He's a man who, like you, wants to hike the Otter Trail when he's 115. Ezz represents his personal effort to navigate the icebergs, build himself a lifeboat, and bring along his friends. Ultimately, Ezz is Dr. Krongrad's vehicle for pursuing knowledge, friendship, and freedom.
