I trained my son Nick starting around age 10-11 prior to that he only played baseball..Since i played a lot at the 4.0-4.5 level i was able to drill him several times a week until he got on the HS team at 14..,He was a stocky kid with a good serve motion and liked coming in since Sampras (my favorite player ) was big at the time ..One key thing i did was to get Nick consistent matches against older guys 4.0-4.5..
At 16 he started playing Level 2 USTA and would lose more often than win but he kept at it..and slowly improved but would lose to consistent baseliners, while he had a one hander backhand..He had a good HS career in a mediocre league and started applying to colleges..He really wanted to go to Tufts in Boston and applied but his Sat scores were 1250 and they turned him down immediately..I knew my son had potential and his Sampras game would need development so i called the Tufts coach..he told me his team was stacked with upperclassmen and would need USTA tournament results to justify his involvement..I explained this to Nick and he was going thru a growth spurt after his Senior year season so he killed himself that summer and just blossomed..His serve got bigger and his attack game matured..He won 3 USTA Level2 tournaments and the Tufts coach got him in as an alternate..He lasted one fall season on the team then quit and joined the ROTC Navy program then switched to Marines..He would get up 4am every morning and travel on his bike (no car) in the freezing weather to Harvard Univ ROTC to make up a semester he lost..He also would spend weekends in ROTC..
He graduated in 2008 Magna Cum Laude and the only student in his school to be commissioned a Marine Corps officer
He completed 2 tours in the Middle East, came back and spent 2 years at the White house met his future wife (also a Marine Captain) doing Special duty and getting to know Pres Obama and his wife so well they were invited to his wedding..He also got his Masters degree at Georgetown on his own time..
2013 he applied for a newly formed Marine Corps Special Forces..It was a grueling 9 month course of combined Navy Seal and Green Beret training..83 men started (including seasoned combat vets and former D1 athletes) but only 45 finished..When i asked Nick how he made it through he said it was the water torture..He said there is not a worse feeling in the world than dying from drowning which is why many guys failed..I also learned later that the Marines let some NFL football players and UFC fighters try the course as an experiment..None of them lasted..While they did ok in the physical part..It was the simulated torture, being dropped in the ocean miles offshore, starvation for days etc.. that did them in...
Another tour in Middle East 2017 then he put in his resignation papers moved to Philadelphia and was accepted to Wharton Business School..But the higher ups said they needed him for one last important mission so he is now currently in Afghanistan and promised me he will resign next month when he returns..Wharton told him he would have to reapply lol.. He does credit tennis for his mental toughness..
Here is his college video from 2004
I don't see him much but we got to play some fun points in 2015..He hadn't picked up a racket in many years but with some practice he could be good..Not bad for a kid with 1250 college boards who couldn't get into his college of choice or play on their team..
