Query: An important tool for marriage counselors

I'm a marriage and family therapist in Eastern Iowa/Western Illinois and I've found that I am able to do my job as much more effectively with JGray's Men Are From Mars... It's simple, honest, direct and does not require the client to do more...just to do things a little differently. This is good news to the client and great news to me because it's my wish to see clients be more satisfied in their relationships. Gray has set a new, positive direction for marriage counseling.
