Dr. Michael Smith 123 ABC St. New York City, NY 99999 April 17, 2016 Dr. Patricia Brown University of California, Los Angeles Medical Center 777 Medical Dr. Los Angeles, CA 11111 Dear Dr. Brown, I am the chairman of the 2016 Metropolitan Medical Conference that is being held this year in Miami, Florida on July 5, 2016. I write to invite you to present your groundbreaking research on beta blockers with our conference participants and invited guests. A 30-minute discussion of your work along with a 20-minute question and answer session would add so much to the intellectual landscape of our annual medical conference. The Metropolitan Medical Association would be pleased to cover your travel and lodging expenses while you visit the conference, in addition to providing a per diem budget during your stay. Please reply with your answer as soon as you are able so that we may begin making arrangements. I encourage you to contact me with any questions or concerns. Kind regards, Dr. Michael Smith
