Mr. Keith Waldman and his associates at OPA are not your standard consulting group. Their ideas, messages, and teaching methods are unique and highly effective. They created a fun, interesting, and non-threatening atmosphere that allowed the most critical of my employees to learn and improve their performance. OPA helped us generate a considerable improvement in our teamwork that led to significant improvement in our results. OPA was an investment in my people and our objective that is paying returns to us tenfold every month.”Mr. Christopher DefillippisDirector of Network SalesAT&T Telecommunications
