Welcome to Sts. Markella and Demetrios Church!

We would love to have you visit us.  Our Parish is a warm, welcoming group of faithful Orthodox Christians who are working to provide a stable, happy spiritual home for those living and visiting Florida’s lovely Emerald Coast.  We have a beautiful Church building which was opened in 2007, and the Parish has been serving the local area since 1964. 


We are located on scenic Hwy. 98 in Mary Esther, FL,  just outside the city limits of Fort Walton Beach. 


Please contact us and come visit!  We pray that you will find our Community to be a happy and vibrant place to bring yourself, family and friends.


Kindly contact me for information, or if you have any questions.



Fr. Thomas Guerry

Presiding Priest
