Danny got immediately addicted to golf at 18 once he, his dad, and his brothers needed a new way to compete in early adulthood. His passion for the game is centered around the joy and grind of being the only sport where you are competing against yourself day in and day out. He built his own simulator 10 years ago, but is looking forward to taking it to the next level as part of the Champions Team!
Danny knows the game looks easier than it is and plans to focus on simple and clear paths to improvement. He wants everyone to leave a lesson having built a relationship, had a fun time, and developed a plan towards getting better even if only slightly! If you are addicted like him, and want to get better to beat your friends or just because you NEED to, Danny will help get you there!

Peter is a 25-year Class A PGA Member. He has worked at private, public and big box retail facilities. With numerous years of experience as a certified club fitter and thousands of golf lessons given to all skills levels.
Every golfer has their own swing and their own personality. I like to understand my student’s personality and what they want out of their golf game. Often players being a beginner, or a seasoned veteran are subject to swing changes and that can be very challenging for a player of any level.
I believe in taking a player’s weakness and making it a strength in their game. I will give you a plan that with a little effort you will begin to see the rewards. More pars, more birdies and most importantly MORE FUN!!
