It all began with a post-army trip to Thailand - and since then, it became a way of life. I split my time between Israel and Bangkok, constantly exploring, researching, and deeply understanding the culture, people, beaches, the north, and the major cities. Over the years, I have created hundreds of customized itineraries, guided travelers from Israel and around the world, and written practical travel guides for smart and meaningful trips in Thailand. I’ll be happy to share my knowledge and make your trip accurate, meaningful, and truly unforgettable.
