Doc Ping Delivers
I quickly discovered that he was a mentally tough and aggressive person. Doesn’t take no for an answer, a hard-line negotiator, but very fair and honest. He is one of the very few sports agents in the business who has won the admiration and respect of all the NFL team negotiators as being a solid person and an excellent business man. Once Doc gives you his word that an agreement has been reached, it’s done, you can count on, he delivers; there is no mincing of words with him.

Ping helps outsider into NFL
Sheldon’s journey to the pros had a limping start. Tiny Grand Valley State was the only school to offer a scholarship to the six-foot 1 inch, 225 pounder from Villa Park, Illinois. But he grew 4 inches and 80 pounds by his senior year. His agent, Dr. Da-I Ping --- a holistic practitioner near Detroit who also represents athletes, including Raiders cornerback Lionel Washington – told Sheldon that he probably would not be drafted that spring. Still, Ping promised to get him a chance at pros, and he delivered a week later.

"What you put into it is what you get out of it," said Holman, the Bangles’ tight end whos completed his seventh summer with Dr. Ping. "He will never fail you. You have to fail yourself. This is a tremendous help, both mentally and physically. After the grueling workouts, you can ease into training camp."
