Teaching
Phil taught private trumpet for 23 years in Plano, working with middle and high school students (mostly Plano ISD). Many made All-Region and All-State — including first chair All-State in Texas. Others earned music scholarships to places including Juilliard, Eastman, NEC, Northwestern, USC, and Baylor. Students attended Tanglewood. Many held principal chair in the Greater Dallas Youth Orchestra (GDYO).
That studio experience is why HYKOM is free, contest-type skills with original drills, assign links for teachers, and progress that can stay on the student’s phone.
Now
He moved on to teach at scale in post-training leadership in Human Data at SpaceXAI. practice cents is still the same idea as the studio: short sessions, a clear target, and tools that stay out of the way.
