Meet the Critter Squad Team


Geoffrey Mantonya is the founder of The Critter Squad, a company many have come to know and love. A true lover of animals, Geoff started a company called Manton Reptiles when he was only 19 years-old. The company’s main focus was towards captive reptile breeding programs. Through his future experiences in the animal world, and through his own University education, Geoff realized the importance of educating the public, so he transformed his business into a wildlife education company. Through this, The Critter Squad was created. Geoff is now 31 years-old and his company, The Critter Squad, is strongly known for their extremely exciting and educating animal outreach presentations. As The Critter Squad moves into the future, Geoff is leading the pack into new worlds. He has started new wildlife endeavors, such as humane animal trapping and release programs, captive breeding programs, and a few other secrets waiting to emerge. Geoff is eager to continue educating the community and making a difference in the world of wildlife.
