"Life/Game changing lessons. Cal has revolutionized my golf game and made golf enjoyable for me again. Being a D1 athlete can be tough and cause you to get worn out easily and Cal revived me in that sense. I want to get out and start practicing more. Incredible human!"

"I have had a great experience with Cal. I am in my fifties and looking for a swing that works with my body and give me consistent results. Cal has made his instruction simple, effective and repeatable. He always ties the lesson to a swing thought I can take away. I’m swinging better with less effort and enjoying the results. I highly recommend that you check him out!"

"Callahan is a very personable young man who cares greatly about all of his students. I have seen the smiles he puts on every person’s face that he interacts with, and it never fails to amaze me. His very interactive teaching style helps you improve at a fast rate."

"Professional and very easy to work with. After my first lesson, I can already tell I made the right choice on who I picked to be my coach. Get in now before Callahan is completely booked and you miss out."

"I had a top notch experience. Cal queried what I wanted to work on and quickly determined what I was doing wrong and how to fix it.I started hitting better iron shots immediately. Even better, through use of video, Trackman, and simple physics he was able to explain why what I was doing caused my problem and why the fix worked. I’m an engineer and knowing why will help me make permanent change. I had more trouble with my Driver but with some additional patient explanation I made great progress there too. I highly recommend Mr Callahan to everyone."
