In the email I first want to state the reason I am connecting them. So I state the problem and why I feel like making this connection is the solution. I also like to share my personal experience with the person that I am referring the client/patient to. This allows the client to see that I trust this person and how he/she has helped me. Additonally, I like to emphasis what sets this person apart from his/her competition. I also want to share that I am available as well moving forward and provide a segue for them to communicate. From there they can set up a meeting.
