Bio — this profile sorts the verifiable facts from the rumor pile: his family, his net worth, the illness talk, and the season 13 questions fans still ask.

Six facts, one pattern: the reliable numbers come from screen credits and public records, while wealth and body measurements stay estimates.
| Fact | Detail | Source |
|---|---|---|
| Known for | Dennis Reynolds on It’s Always Sunny in Philadelphia | IMDb’s actor page |
| Born | 1976, in Japan | GQ’s interview profile |
| Family | Married to Jill Latiano since 2009; two children | Scopepress profile |
| Education | Graduated from Juilliard’s Actor Training Program | Apple TV’s biography page |
| Height | About 5’9″ (1.75 m) | Scopepress facts article |
| Net worth | $25 million (reported estimate) | Scopepress career profile |
The trade-off: fans want one clean number, but the honest answer is that Howerton’s net worth is an estimate, not a public filing.
Does Glenn Howerton have a kid?
Yes — the family facts are among the best-documented details in Howerton’s public life.
Who is Glenn Howerton married to?
- He has been married to Jill Latiano since 2009 (Us Weekly’s celebrity profile).
How many children does Glenn Howerton have?
- Two children, according to the same Us Weekly biography.
What this means: the personal-life questions search engines keep surfacing have a simple, consistent paper trail — even when the rest of his biography is scattered.
Why did Glenn Howerton leave Always Sunny season 13?
Was Glenn Howerton fired from Always Sunny?
Not fired — scheduled. Howerton’s NBC series A.P. Bio conflicted with Always Sunny’s production calendar.
The public explanation was scheduling: Howerton was leading A.P. Bio when season 13 went into production, so he appeared in only a handful of episodes. He returned for season 14 and has stayed with the show since, according to Scopepress’s career profile.
What projects did Glenn Howerton pursue during season 13?
- He starred as Jack Griffin on A.P. Bio from 2018 to 2021 (Scopepress career profile).
The pattern: the Always Sunny hiatus was a calendar problem, not a loyalty problem — and the show kept the door open for his return.
What movies has Glenn Howerton been in?
What are Glenn Howerton’s most famous movies?
- BlackBerry (2023): played Jim Balsillie (Vanity Fair’s awards coverage).
- Must Love Dogs (2005): feature-film debut (Apple TV’s biography page).
- Cooties, The Chumscrubber, and The Hunt: cult and horror-comedy credits (IMDb’s actor page).
- Showtimes’ biography also lists The Strangers, Everything Must Go, and Officer Downe among his film credits.
What TV shows has Glenn Howerton appeared in?
- ER, The Cleveland Show, and The Mindy Project all appear in his TV résumé (Showtimes’ biography).
- He made his first credited screen appearance as Dick Ebersol in Monday Night Mayhem (Apple TV’s biography page).
- His credits also include A.P. Bio and Fargo (Scopepress career profile).
The pattern: his career cycles between broad comedy and sharp character work, with Always Sunny as the anchor.
Who created Always Sunny?
Was Glenn Howerton a co-creator of It’s Always Sunny in Philadelphia?
- Yes — the show was co-created by Rob McElhenney, Charlie Day, and Howerton (GQ’s interview profile).
- Before that, Howerton was an Air Force brat: his father was a fighter pilot, and the family moved frequently (Icon Vs. Icon’s interview).
- He has also said he considered aeronautical or aerospace engineering before choosing acting (Icon Vs. Icon’s interview).
Why this matters: the show’s origin is a creator-driven success story, not a network development project.
What is Glenn Howerton’s illness?
Does Glenn Howerton have any known health conditions?
No public diagnosis connects to Howerton himself; the “illness” talk almost always draws on Dennis Reynolds’s on-screen behavior.
Neither Howerton nor his representatives have disclosed a medical condition, and as of 2025 he remains active across film and TV, per Scopepress’s facts article.
The takeaway: if a “Howerton illness” claim appears online, check whether it is describing Dennis, not Glenn.
