Great experience. Very professional and thorough. The instructor adapts to your learning abilities and makes a very serious effort for you to understand the concepts. I am sure that my game will benefit from this experience. Thanks!

Dennis Clark is an amazing teaching instructor. I am a long time single digit player struggling with “the shank”. This devastating shot comes out of nowhere and rears its ugly head generally at the worst of times. Dennis identified my issue on the first swing and went on to correct my swing flaw. I’ve utilized instruction from top golf professionals nation wide. No professional instructors compare to Dennis Clark. His status of Master PGA Professional is well deserved.

Dennis and I have been working together for more than a decade. I owe a lot of where I am today with golf to him. His knowledge about the game and swing is like no other.

Janice Byers

I have been taking lessons with Dennis Clark for several years. He has taken my game to a much higher level. Like all golfers there are times that I regressed, and Dennis is able to instantly get me back on track. I am also grateful to have my stash of lesson videos that I refer to often, and find extremely helpful. Dennis Clark is the best golf instructor that I have ever had! Hands down!

Thx for all your help. I won our club championship at The Sanctuary two weeks ago. Never expected that but played well against our top players and proved in match play anything can happen! I really appreciate your help along the way.

Bernard Sheridan works very well with my son and his game has really improved as a result of Bernards’ instruction.

I am so happy I invested time to do this! I am a Junior Golfer, with two Junior World Runner-Up titles including two Jr World Tournament Low rounds. As a Freshman in the fall of 2019 I won the NorCal High School championship and low round record holder. I have had significant coaching and this season has been the most amazing to date.

I am a Professional Golfer playing on the Symetra Tour and I just had my first putting training session with Bernard Sheridan at IZG. He is a fantastic instructor and he was very thorough with each part of the putting lab. I came in with a goal of what I wanted to achieve and he went above and beyond to make sure I left feeling confident in what I had learned. I am extremely happy with what I took away from the session, and I would definitely recommend seeing Bernard at IZG!

Anthony Senagore

Bernard was clear, concise, and precise in explaining need adjustments to my swing. One of the best approaches to swing adjustments I have experienced
