Dear Mrs. Smith,

As one of the member in the ABC Medical Organization, I endorse the application of Dr. Phillip Anderson for membership in our organization.
I have known Dr. Anderson for almost two years and he is one of my trusted friends when I am taking my mastered degree at ABC School. I know that he is suited with our organization. He has been practicing medicine in ABC Hospital for almost two years.
Please let me know if I can provide any further information in support to his application.

Sincerely,
(Signed)
Michael Walker
