PGA Instructor in Central NJ has one goal for all his students; to gain the ability to believe in yourself and therefore have more enjoyment on the golf course.

Keith is a 20+year PGA Class 'A' Professional, Callaway Staff Member, TaylorMade and Titleist Club Fitter, in the expertise golf instruction, golf biomechanics, and junior coaching. Keith has spent the last two decades teaching the game of golf alongside top-25 teachers Jim McLean, Carl Welty, and NJ Teacher of the Year nominee Warren Raatz.

Each student is evaluated to determine their natural: Swing Plane, Lower Body Action (One Post, Two Post or Lateral), and Hip Speed. Ideal Setup ( Grip, Posture, Stance, Ball Position, Aim and Alignment), Dominant Power Source, and Range of motion.

Each student is video taped with high-speed video (300 to 1000 FPS with 1/20,0000 shutter speed), evaluated with FlightScope mevo to determine your ball speed of each shot with launch angle and distance.

Once the student has been evaluated, then the process begins in transforming their swing. The initial phase are to identify the area that is preventing them from maximizing their effort through drills and the utilization of training aides.

The final piece is designing a program to optimize their performance on the golf course. Playing better golf isn’t just swinging better. That is why Keith not only will make you hit the ball better, but he will teach you the short game strokes to shave shots from your score, he will also take you on the golf course to teach you how to manage yourself on the course to maximize your performance. The art of learning how to play your best golf regardless of how you are hitting it.
