D1 Training announced the appointment of Clif Marshall as Senior Director of Coaching and Pro Training on Wednesday. 

Marshall, a nationally recognized strength and conditioning coach, brings more than 20 years of experience training elite collegiate and professional athletes.

Marshall's career includes stops at:

  • Indiana University
  • The University of Dayton
  • The Cincinnati Bengals

Marshall also served as Performance Director at Ignition Athletics in Cincinnati, where he led its NFL Combine Training Program for a decade.

As Senior Director, Marshall will spearhead the development of D1’s Pro Training Program from its headquarters in Franklin, Tenn., with a focus on preparing collegiate athletes for the NFL and NBA combines.

“I am humbled and honored to join the outstanding team at D1 Training,” said Marshall. “It’s a privilege to lead D1’s Pro Athlete training division, and I’m eager to work alongside some of the most elite talent in the NFL, MLB, NBA, and WNBA. My deepest thanks to Will Bartholomew for his trust and belief in me. Above all, I give praise to God for granting me the opportunity to equip and encourage coaches and athletes across the country.”

The hiring follows Marshall's appearance at D1's Coach Summit in June, where he spoke on the importance of training the whole athlete.

“Clif’s training philosophy goes beyond physical performance, he focuses on building athletes from the inside out,” said Will Bartholomew, Founder and CEO of D1 Training. “With his track record of preparing high-profile athletes, his leadership will elevate our combine program and strengthen D1’s position as the nation’s premier training franchise.”
