Thank you for looking in our website to learn more about the Jewish community here on Marco Island and our corner of Collier County. A deeply rooted part of the local faith community, our synagogue is home address to the local branch of the Jewish people, a richly diverse population of your fellow Israelites— all of whom have, pretty much by definition, come from somewhere else.
I am honored to be able to serve as spiritual leader and resident story-teller, Torah-teacher, and arbiter of authenticity to this local bastion of Jewish richness. And I am deeply proud of the dynamic and committed cohort of local Jews whose imagination and dedication have built this community as a nurturing home for us all.
That includes you! Don’t settle for a virtual visit to our site; drop by and meet us soon or please feel free to contact me directly RabbiMarkGross@gmail.com

“Sing a new song unto the Lord.” That’s what we read in the 96th Psalm, and that’s what we do at the Jewish Congregation of Marco Island. Music is an integral part of our everyday temple life. Whether you come to attend services, lectures, classes, concerts, or social events, we look forward to meeting, getting to know, worshiping with, and working beside you.
While we are most predominantly a Reform congregation, our members’ backgrounds include Reform, Conservative, Orthodox and Reconstructionist. Therefore, our choices of musical settings mirror that rainbow of interpretations. Whether you love to sing along, never sign along (but love to listen), sing off tune – whatever- we welcome you. We welcome you with traditional settings, contemporary settings, and Nusach. We even take requests.
Not only do we sing a new song unto the Lord, but we sing unto the Lord together. We hope you will join us, as we look forward to praying, studying, and kibitzing with you at the Jewish Congregation of Marco Island.
