I'm a current BP instructor, and I actually took Phil's course way back when. He knows the material backwards and forwards, but I'd say his number one asset is being a fun and charismatic guy who keeps the students engaged. You'll be spending dozens of hours pouring over the LSAT with your instructor, so it helps to have a bearable one. He's entering his seventh year with Blueprint, and his students average an eleven-point score increase from first to last practice exam.
If you have any further questions, we'd be happy to arrange a time where the two of you could talk by phone, email, in person --whatever you'd prefer. Best of luck in your studies.
