I agree with MAFCDL,
Its a direct approach to getting more information as well. Perhaps this individual has already laid groundwork with someone else?? Perhaps you could use this to your advantage as well. If he is unwilling to meet with you to discuss your intentions than the ball is still back in your court. Market heavy, using your knowledge of his closing with a tag line of "no stressful transitions" I have found that when a client is FORCED to look for a new lab its their stress level that dictates a bunch of snap decisions.
Carpe Diem!
