I am trying to network with doctors and physical therapists in my area to get some patient referrals. Can someone please share some ideas with me on the best way to do this? I was thinking of sending a letter or email introducing myself and then following up with a phone call? What have others experiences been with this? Is it best to try to schedule a face to face meeting with a doctor? I want to be aggressive enought to not be ignored without being annoying. Any advice would be appreciated.
