PGA Professional Staff

Peter Donahue

Founder | Senior Coach


My office is out in the fresh air under some big oak trees. The people with whom I work are all curious, eager, and motivated. I advocate for the game of golf, and also for studentship and evolution. I’m living a dream that I first dreamed fifty years ago. A kid’s dream for sure. Then again, aren’t all the good dreams?

I wake up early out of long habit, and usually arrive at the golf course to enjoy the quiet around sunrise. I wake up my game by pitching and running shots onto the green from out in the fairway. Exchanging morning hellos with familiar smiling faces riding their machines out to make the greens ready for the day, pretty soon the birds and the squirrels will be joining us. It’s our morning meditation.

Chris Oehlerking

Managing Partner | Senior Coach 

Chris, a proud native of Canada, has a passion for helping people who have a desire to learn.  Chris believes anything can be learned when commitment, consistency and patience are present.

Teaching Philosophy
Chris educates his student on why certain shot patterns occur.  He instructs them on what specific changes will make an immediate impact and then coaches the player through the process of learning that particular skill both physically and mentally.  Chris’s hands on approach provides a unique kinesthetic experience that enables the player’s body to interpret the correct feel.

Ty Treacy

Junior Program Coordinator | Lead Coach

Ty's love of the game of golf began at the age of 5 when his grandfather gave him his first set of clubs, he hasn't put them down since! When other kids went to the pool or to camp in the summer, Ty went to the range and practiced,
and loved every minute of it.

The introduction of Harvey Penicks "Little Red Book" by his grandfather was a turning point,  from golf being a game, to a passion that continues to grow each day. A native of the Winnetka, Ty found early success  in tournament golf at the local and state level. He played for New Trier High School and went on to play collegiate golf at Division I, DePaul University. Ty turned professional at the age of 23, attempting the mini tours and PGA Tour qualifying school. It was after this humbling experience that Ty decided to teach the game he loved.

Dr. Arthur Hoffman

Dr-Arthur-HoffmanMindfulness Based Mental Conditioning Coach

Dr. Hoffman started with our Academy 4 years ago, but as a student. As time passed there was a connection around the mental side of the game and Peter & Chris realized what an asset Arthur's knowledge could be to the Academy's students. Arthur joined the team last year and began teaching mindfulness to the Master 360 program participants.

Mindfulness training is a training, or one might say re-training, of the mind.  This training awakens, and strengthens, neural pathways of the brain that are inherent in us all, but are often sleeping through our day by day lives, not to mention during the preparation for, and execution of, a golf swing on a golf course or in a golf tournament.  The practices lead to being present to our experience more often and on autopilot less often.
