Papa Jackson

2007–2016: Career beginnings; TLC: True Love Conversations

Prior to his career on radio, Gemperle started out as a call center agent but was also a listener of the Tambalan program on 90.7 Love Radio that aired on a late afternoon time slot by Chris Tsuper and Nicole Hyala.

Upon Love Radio conducting a DJ search in 2007, the 24-year old successfully got hired, beginning his career under his persona known as "Papa Jack".^[1] In mid-2007, he launched his love advice program TLC: True Love Conversations, which became one of the most popular radio shows in Metro Manila.

In 2013, Papa Jack and then-101.1 Yes FM DJ Chico Loco (Mark Jimel Gales) collaborated for a weekly program Gabi Na, Gising Na!, which lasted for 2 years.

He later ventured into television hosting, starting off with the talk show Star Box, alongside Ali Sotto on GMA Network. In March 2015, he became the host of his own program Call Me Papa Jack on TV5. ^[2]

He also became a brand endorser for Motortrade, with rapper Gloc-9 and Julie Anne San Jose (formerly with Denise Barbacena).

2017–2026: Rebranding as Papa Jackson ; Hello, STG

On December 16, 2016, Papa Jack made his final broadcast of his nightly radio program, and eventually resigned as a DJ of 90.7 Love Radio. Gemperle did not specify complete details about his resignation.

Prior to his final broadcast on 90.7, his last co-host was DJ Kara Karinyosa (Klariz Magboo); the chemistry of both led to listeners nicknaming the tandem on-the-air as KarJack.^[3]

On March 20, 2017, Papa Jack transferred 106.7 Energy FM and launched a new program, Hello... STG (Sorry, Thank You and Goodbye). The show initially ran every Monday to Thursday from 9pm to 1am until the creation of Gabi Na, Umaga Na! on Fridays starting May 8, 2017 with the return of erstwhile collaborator Mark Jimel Gales (who, by that point, assumed the name of Kuya Chico). The duo would be later re-joined by DJ Kara on February 6, 2019.

Upon his move, Gemperle used "Papa J" as his new monicker but was eventually renamed to “Papa Jackson” on April 2017 to avert confusion and trademark issues as his former employer held the intellectual rights to the "Papa Jack" on-air name. He also served as the program manager of 106.7 Energy FM until November 2018 when he was promoted to station manager following significant listenership ratings gains. Gemperle would resign as station manager in October 2025 but remained as a regular DJ on Energy FM until fully departing the station on January 2026.

2025–present: Petty Nights: move to DWIZ

In October 2025, amidst changes and uncertainty with his position at Energy FM, Papa Jackson expanded his media presence by launching Petty Nights, a digital talk series on his official PAPA JACKSON YouTube channel, featuring a similar format of his earlier radio programs. Episodes of Petty Nights were released regularly on the channel while seeking his future options.^[4][5]

On March 3, 2026, Aliw Broadcasting Corporation signed Gemperle and Mark Jimel Gales (Kuya Chico) as hosts for their flagship broadcast properties DWIZ-AM and Aliw Channel 23. The 43-year old veteran will host the love advice program Love Discussion and Reactions, set to begin in April 6, 2026.
