Pejman was my guide in exploring the outskirts of Mashad. He was more like a personal host than a guide. his knowledge of the area is great but he's also a good conversationalist - you'll find him pleasurable to spend time with and at the same time will get good insights into Iran, it's culture and society.  On top of knowing his subject matter well, he has a lot of experience in interacting with people of different cultures and is comfortable in doing so. I'd highly recommend him for any type of guide services in Iran.
