I always had this desire...but I had a chance to do something that I felt 'helped' more...It was DF, and Dr. G and Dr. D asked our family to participate in a local medical information show...so we packed up the kids and participated in the filming of the show. Alas, filming went bad in the first round...so we packed up and participated a second time.
I think they appreciated our efforts!
Now, I send a yearly update photo...Dr. G always graciously replies.
I also think...if your really happy with your success and your practice...that you continue to post on threads like this, to boost the public face of the practice.
I know that Dr. G has always thanked me for my posts on his personal blog and DF's FB page.
