OPOS Turkey Office

OPOS Tours and Travel was established by  Christopher Prescott and Sonja Goodwin Tanner. Both owners are enrolled Native American Tribal members. Together they formed OPOS Tours and Travel in the hopes of sharing “Our People Our Story” with the rest of the world.

OPOS then expanded to Turkey where Gokhan Dogan and Sara Korukcu, experts in the tourism sector, manage the branch located in the heart of Old Istanbul. They share the same passion as Chris and Sonja and thus they are committed to offering people from around the world the ideal opportunity to experience the best of Turkey. From the rich history and culture residing in every corner of Istanbul, the once Byzantine and Ottoman empires’s capital, to the unspoiled nature and magnificent scenery in the numerous UNESCO World Heritage sites in Turkey such as Cappadocia and Pammukale. Our aim is to help you enjoy Turkey’s unique ambience where east meets west and Europe crosses paths with Asia.

OPOS Turkey offers a variety of custom, private, and general tours to the interest of everyone. From Daily City Tours in the charming city of Istanbul to all regions of Turkey. We will guide you through our lands, into our culture, or languages, our foods, to hear our history as can only be known by us. Our guides will share our stories and teach the rich history and wisdom of our people which remains as relevant today as it was thousands of years ago. Our tailor made tours offer you the choice to meet with one of our Cultural Ambassadors to help design your own tour. In addition to tourism, we organize conferences and meetings for various organizations and businesses. We have developed a loyal client-base and earned a good reputation for the diversity in our tours and are a member of the Association of Turkish Travel Agencies (TURSAB).
