I have served on over 40 corporate boards and advisory boards. What you can expect from any advisor depends on the advisor's experience base and character. Some advisors take all the air out of the room and require massive amounts of care and feeding. Others are nearly invisible. Probably so long as you understand what you want from the advisor and communicate it to them clearly, you will have good results. Let me know if this was helpful and if you would like to discuss the matter further.
