John O’Donnell turned a simple golf shirt into a clothing business with a national following. His younger brother, Chris O’Donnell, became a familiar face in Hollywood through films including Scent of a Woman and two Batman productions, before finding long-term television success. The brothers’ connection extends beyond celebrity endorsements.
Their story spans Chicago, California, entrepreneurship and entertainment. It also explains why Johnnie-O has become a recognisable name in American golf retail, how Chris has supported the venture, and what both brothers are doing now. Their careers offer a useful contrast between building a consumer brand and sustaining a career in entertainment.

Two Paths Out of the Chicago Suburbs
Both men come from the O’Donnell family of seven children, raised in the Chicago area. Chris, born in 1970, is the youngest sibling and grew up in Winnetka, Illinois. The family’s Catholic background and close-knit household feature in accounts of his childhood, although the brothers have generally kept the more private aspects of family life away from their professional identities.
John’s interests led him towards golf. He caddied in Illinois as a youngster and later joined the University of California, Los Angeles golf team as a walk-on. Those experiences introduced him to golf clubs, professionals and customers.
Chris worked in modelling and advertising before his feature-film debut in Men Don’t Leave in 1990. While John spent years in the corporate world, his younger brother began establishing a screen career.
John O’Donnell Saw a Gap Between Smart and Casual
When John launched Johnnie-O in 2005, his idea was specific: combine the neat, traditional clothing familiar from the Midwest and East Coast with the relaxed character of Southern California.
A golf trip with friends helped crystallise the concept. John wanted shirts that looked appropriate at a club without feeling excessively formal away from the course. The first product was a polo with four buttons and a chest pocket, a small departure from standard designs that gave the business something distinctive to sell.
He initially moved merchandise himself, including from his car, rather than beginning with a large chain of shops. The surfer-inspired logo reinforced the coastal influence without abandoning the brand’s golfing roots. The result was preppy clothing intended for life beyond the fairway.
Why Golf Shops Became the First Serious Market
John was not originally trying to create a golf-only label. Nevertheless, relationships with club professionals gave him a practical route into retail when conventional fashion buyers were harder to reach.
He started with contacts who knew him and understood how their customers dressed. Golf shops became a testing ground for shirts that could also be worn to lunch, at work or on holiday. Johnnie-O adapted familiar staples rather than imposing a new look.
That positioning coincided with wider changes in golf merchandising. Pro shops increasingly offered lifestyle clothing alongside equipment and technical sportswear. Johnnie-O benefited from that shift, giving the company a distribution channel that suited its identity.
From Early Polos to an Established Apparel Business
The range eventually expanded well beyond its original shirt, adding knitwear, trousers, outerwear and clothing for women and boys. The company also developed its own shops and online sales alongside independent retail distribution.
In March 2025, Forbes described Johnnie-O products as available in nearly 2,500 American golf shops, with 12 branded retail stores at that point. Those dated figures demonstrate its growth but are not a current store count.
A further milestone came in 2022, when funds associated with Wasatch Global Investors and Ares Management invested $108 million in the company. The financing involved a minority stake and supported expansion. It did not mean John personally received that sum, nor does it establish a public valuation of his individual shareholding.
The business has also pursued licensing relationships with Major League Baseball, the National Hockey League and college sports. Such partnerships take the brand beyond golfers.
The Distinction Between Founder and Chief Executive
John remains publicly associated with Johnnie-O as its founder and has continued discussing the brand’s direction in industry interviews. He is not, however, the person to identify automatically as its chief executive. Dave Gatto has held that operating title, representing the management structure that accompanied the company’s growth.
Founders can shape brands while executives manage operations. Public information does not provide a complete, continuously updated picture of John’s personal ownership percentage.
Chris O’Donnell’s Breakthrough Came on Screen
While John’s business was still years away from launching, Chris was already becoming recognisable to cinema audiences. He appeared in Fried Green Tomatoes and School Ties, but Scent of a Woman in 1992 was an especially important career moment.
Playing a student opposite Al Pacino, he received a Golden Globe nomination for supporting actor. The performance established his credentials in character-driven drama.
Greater commercial exposure followed when he played Dick Grayson, also known as Robin, in Batman Forever in 1995 and Batman & Robin in 1997. The two films remain conspicuous entries in his filmography, although his subsequent career moved through a much wider range of genres.
The Television Move That Changed His Career
Chris appeared in projects including Kinsey, Grey’s Anatomy and the miniseries The Company, before television became the centre of his professional life.
From 2009 to 2023, he starred as special agent G. Callen in NCIS: Los Angeles. Fourteen seasons gave him a character audiences followed for more than a decade. His partnership with LL Cool J was central to the series.
He is now part of ABC’s 9-1-1: Nashville, playing fire captain Don Hart and serving as an executive producer. The drama debuted in 2025, with its second-season premiere scheduled for 15 October 2026. This is a current television role, not an extension of his completed NCIS run.
How Chris Fits Into John’s Business Story
The brothers’ connection extends beyond sharing a surname. John has openly acknowledged Chris’s support for the company, while golf-industry coverage has described the actor as an early investor in Johnnie-O.
Chris has also worn the clothing and appeared alongside John in public settings. That visibility helped introduce the brand to audiences who might not otherwise have encountered it in a golf shop.
Yet John has resisted presenting celebrity association as the company’s central selling point. In interviews, he has emphasised that recognition cannot compensate for unconvincing products. Chris brought an audience; John developed the products and the business.
Their professions nonetheless demand different skills. One sells an ongoing wardrobe proposition; the other brings characters to life across individual productions and long-running series.
Public Success Does Not Reveal Private Wealth
An investment headline is not a personal net-worth statement. Johnnie-O is privately held, and the precise value of John’s remaining interests is not comprehensively disclosed. There is no sufficiently reliable public figure to present as his verified net worth.
The same caution applies to estimates of Chris’s fortune circulated by celebrity finance websites. Earnings from acting contracts, investments, taxes and personal assets are not publicly documented in enough detail to calculate his wealth accurately.
In both cases, their professional achievements are better established than their personal balance sheets.
Conclusion
John O’Donnell built Johnnie-O by recognising a specific clothing preference and finding retailers positioned to serve it. Chris O’Donnell developed from a prominent young film actor into a durable television presence, with another major network role in progress.
Their shared family background makes the comparison compelling, but their independent accomplishments explain why both names remain relevant. The lasting connection is not simply Hollywood meeting fashion; it is two brothers working within different industries while occasionally helping each other’s ambitions.
