Perry "Big P" Prine of Euclid, Ohio is a yo-yoer, modder and store owner. He is also best known under the nickname "Modfather", particularly when selling his modified yo-yos. Although he will attempt any mod, he tends to use Duncan yo-yos and sells his mods exclusively through his own store in the U.S. (and Euro-Yo for the U.K.), though some examples of his work were sold on Yoyoguy. He specializes in one-of-a-kind modified yo-yos. Perry has a certification in precision machining from Willoughby Technical Center, in Willoughby, Ohio. He graduated in 1995.
Prine earned a spot in the Fall of 1999 on Honolulu, Hawaii-based Team High Performance while working as a yo-yo demonstrator for Yo-Yo Universe/Mackinaw Kite Company of Mackinaw City, MI. No titles have been won by Prine in yo-yo competitions. Currently, he is involved with two yo-yo clubs based in the Cleveland, Ohio area.
