Meet the Team

Not many demigods survive to adulthood, but those that do are always committed to keeping Camp Half-Blood an active, magical, and amazing place for young heroes in training. Older demigod counselors come and go each year (personal quests and whatnot), but these are the amazing people you will be sure to meet this summer.


Crystal Bobb-Semple (definitely not "Camp Mom")

Crystal (or Persephone as she’s better known at Camp Half-Blood), is our resident goddess and fearless leader, and the founder of Camp Half-Blood and its parent company, Plato Learning. The favorite daughter of Demeter, she loves kicking back with a good book, soaking in the sun on nature walks, cheering on both cabins in each week’s dodgeball championship, and wiping the dirt off many a camper’s face in front of the snack cornucopia. Her creativity and love of adventure help her to develop and execute the CHB storyline each year from start to finish, and her passion for cultivating artistry, imagination and leadership in kids makes her beloved by campers and staff alike. From strategizing creative ways to bring Odysseus’ journeys to life with the Quest Staff, to leading campers through the woods towards the oracle, to channeling the healing powers of Apollo to regenerate a limb lost in battle, Crystal is to thank (or blame) for the exhaustingly fun environment that is Camp Half-Blood.

Timothy Ling, Warrior Poet, General WashingTim, Giver of Crisp High-Fives

Tim found Camp Half-Blood many moons ago in the year 2012. After years of having his wits and strength tested by relentless monster ambushes, he arrived on the border of camp bloodied, bruised, and breathless. Upon crossing the threshold into camp he was immediately claimed by his Goddess mother, Athena. Tim is now 23 and has dedicated his summers to training younger demigods what it means to be a hero. He strives to impart unto the next generation of heroes, all the skills required for venturing out into the unknown. 

When the seasons demanded he leave Camp Half-Blood and rejoin the mortal world, Tim studied Business Administration and Economics at Hartwick college. He has trained in several martial arts, and finds serenity in Buddhist meditation practice as well as vinyasa yoga. While he is a devout Son of Athena, he often spends time hanging out with demigods from different parents. This summer he will be your guide, your friend, and your mentor.

Alex Tissiere, Bestus of Hephaestus, Pug-master, Receiver of Crisp High-Fives

Alex’s own Quest to Camp Half Blood started in his hometown of Richmond, VA, where he first discovered the magic of storytelling through theatre.  His thespian adventures led him to New York, where he graduated from NYU and embarked on an acting career in NYC (though he still hasn’t been to the 600th floor of the Empire State Building).  As a Director of Camp Half-Blood and a son of Hephaestus the lame god, Alex likes to get his hands dirty, in everything from crafting and building to getting outdoors for some hiking and rock-climbing.  And just as Hephaestus helped teach the arts the mankind, Alex developed at NYU a dual passion to bring his skills and experience in theatre and the arts to students and children of all ages.  From arts outreach programs at NYC public schools, to non-profit work with kids in Madagascar, to now helping create the magic of a Camp Half Blood Brooklyn summer, Alex is committed to providing kids with the same experiences that started him on his Quest in the first place.   He also happens to be committed to finding the best cheeseburger in all of New York (and the world), but that’s more of a side quest…

Brittany Johnson, Linguistic Mystic

Brittany, a daughter of Dionysos (or Mr. D, as he's affectionately called by campers), always is ready to party and is always hip to the latest mortal and immortal gossip. This is why she's our official source for all the trouble-making that goes on over the summer, when the sun is out and - fortunately for us - the monsters are too. She serves as a quest guide, a trivia master, a weapon modification expert, and a part-time armor decorator (have you seen her gorgon shield?) when she is at camp, but can often be found wandering around the park alone, catching up with good guys and bad guys alike, keeping an ear out for evil plots or hybrid beasts that might be hatching right under our noses. Brittany's life outside of CHB isn't actually that different from her life in the summer, as she's taken up the family profession and now teaches Latin and Ancient Greek at a girl's prep school in Westchester. In her spare time, like her dad, she enjoys dancing terribly in Zumba classes, eating too much Mexican food, and watching plays and concerts across the city. She'll be directing her third show, a translation of Aristophanes' Knights, this coming fall, and will talk about it to anyone who will best not to ask.
