Flatstick Focus: Interview with Mark Immelman
In Episode 22, we chat with Mark of all trades, Mark Immelman. To say that Mark leads a busy schedule would be an understatement. Not only does he coach Men’s and Women’s college golf at Columbus State University, he currently hosts the On the Mark Podcast, and covers the PGA Tour for PGA Tour Live, CBS Sports, Golf Channel, and Sirius XM.
Mark is a published author and has written articles for various golf publications. Mark was also voted as a Golf Digest Top 20 Instructor Under 40.
In Episode 28, we chat with leftymoose, a very diverse putter collector from Canada. He has close to 50 putters from several manufacturers and helps shed some great insight into the collecting world.
In Episode 27, we interview Brad Tilley. Brad is a highly-accomplished amateur golfer and putter head.
In Episode 26 Glenn is back and we interview the owner of Legend Golf Company, Joe Legendre.
