Sun Valley Community Church

Sun Valley Community Church is a multisite church headquartered in Gilbert, Arizona, with roughly 10,000 in weekly attendance across campuses in Gilbert, South Gilbert, East Mesa, Tempe, Queen Creek, and Casa Grande, plus online. The church opened its doors in 1990 with Southern Baptist roots and has repeatedly landed on fastest-growing church lists. Chad Moore leads it and teaches live at the Gilbert campus most weekends. The stated mission is helping people meet, know, and follow Jesus.

Sun Valley covers all four major platforms with 202,894 combined followers, and the mix is unusual. Instagram is the lead channel at 92,209 followers on a verified account. TikTok comes second at 56,900, ahead of both Facebook at 28,285 and YouTube at 25,500. That YouTube channel is the growth story, up 32.12 percent in the past year, the fastest YouTube growth rate of any church ranked 41 through 50. New content published as recently as June 9.

A perfect 100 breadth score plus 32 percent YouTube growth makes Sun Valley one of the more interesting builds in this tier. Most churches start with YouTube and struggle to crack short-form video. Sun Valley did it backwards, building Instagram and TikTok audiences that together outnumber its YouTube subscribers four to one, and is now growing the long-form channel on top. The 47.3 velocity score understates the YouTube momentum because the established platforms are maturing. Watch the YouTube number: at the current rate it doubles in under three years, and that would pull the church's reach score up sharply from its current 36.8.
