My Dog Mattis Book Signing

May 16th 

4PM to 6PM

Palmer Plaza

On Sunday, May 16th from 4PM to 6PM, meet Alpharetta Sergeant Mark Tappan and his K9 dog Mattis for his first book signing.

"My Dog Mattis" is Mark Tappan's first book about his celebrity K9 dog Mattis. Mark and Mattis have been a team for over 5 years. Mark is a 15 year veteran with the Alpharetta police force and Mattis is the most highly decorated dog in the department’s history. Mark has always seen dogs as a great bridge to connect law enforcement and the people they serve. They have grown their following on social media to millions. They are focused on using their platform to bring people together with fun and creative posts while giving insight into the special bond between a handler and K9. They appeared on the inaugural season of America’s Top Dog on A&E winning episode four and coming in a narrow second in the Champions Episode.

Books will be available to purchase for $15 or you are welcome to bring your own copy of “My Dog Mattis.”
