Zach is the very best of the best. He is brilliant, Texan native w a great vast knowledge of all industries and all things Texas. He was able to teach and entertain simultaneously my children ages 8, 11, and 13 while we did a spring break sans my husband. He made history super cool. He exceeded our expectations as it was stress free and we beat every line by his impeccable timing. He was also a great role model growing up in a home where he served the homeless weekly. My kids had a blast w his fun and inspiring approach to experiencing the city.
