Summed up in one acronym: “BEST” Ball

(If you have played on a BESTBall Golf Team, then you understand that this is when 4 regular golfers team up. You use the best shot from each team player and play the course together. Not everyone is a “long ball hitter” but each bring their unique talents. The amazing part is that a BESTball team regularly scores better than a professional golfer. This shows the power of ONEC’s team approach.)
