If you’ve come across the name “Cormac Dennehy” online, you might have noticed something odd—there isn’t just one Cormac Dennehy. Several professionals share the name, and their stories are scattered across different industries, from entertainment to healthcare. This makes things pretty confusing for anyone trying to learn more about the name or searching for a specific person.
Let’s walk through what’s actually out there and sort through the details. Consider this your crash course in the Cormac Dennehy confusion.
The Cormac Dennehy Connected to Gersh Agency
Start with the most public-facing Cormac Dennehy. He works in entertainment as a Manager at The Gersh Agency, which is a well-known talent and literary agency in New York and Los Angeles. If you see his name connected with creative projects, branding, or artist management, it’s almost certainly this guy.
His contact details float around public listings and professional directories:
Email: [email protected] or [email protected]
Phone: 212-634-8191
That’s probably information for professional inquiries, talent submissions, or anyone looking to do business in the entertainment field.
Gersh Branding and Industry Moves
If you poke around social media, you’ll find a SoundCloud page linked to Cormac Dennehy. That profile mentions involvement with “Gersh Branding”—which matches up with his position at Gersh Agency. Branding is a significant arm for talent agencies these days, since it handles deals beyond TV, movies, and books—think products, endorsements, and digital content.
One other project stands out on his public bio: he lists himself as “Manager – Shiffley.” Shiffley is an indie pop band from New York City—plenty of folks in the business build parallel careers as artist managers and agency staff. It’s pretty normal if you’re juggling creative interests.
This Cormac also mentions the “Bandier Program” and “#CuseNation.” The Bandier Program is a selective music business major at Syracuse University, and “CuseNation” is a familiar term for the school’s alumni network. So you get a picture of someone who came through a music business pipeline and landed quickly in agency life.
The Other Cormac Dennehy—A Career in Healthcare
Then you have a full-on curveball. There’s another Cormac Dennehy, and he’s listed as the Education Manager for Medical Imaging at Vancouver Coastal Health in British Columbia, Canada. This is a completely different lane—think hospital administration, clinical training, and medical imaging technology.
If you come across a LinkedIn profile or a staff directory list for Vancouver Coastal Health with that name, you’ve probably found this Cormac Dennehy. His day is about making sure hospital staff are trained, certified, and updated on the latest in medical imaging, not artist contracts.
It’s unusual, but not unheard of, for two professionals with the same unique name to end up being discussed online within a few years of each other. This is where you start to see people get mixed up, especially if you’re throwing their names into Google and reading headlines out of context.
Family Ties to Brian Dennehy
But things get even more tangled when you add in one more connection: Cormac Dennehy as the son of Brian Dennehy. Brian Dennehy was a well-known actor—maybe you remember him from movies like “Tommy Boy” or the original “First Blood,” or from his long run of stage performances.
Brian Dennehy passed away in 2020 at age 81. News coverage when he died mentioned that his wife Jennifer Arnott and “their son Cormac” were by his side. At the time, Cormac Dennehy was 27 years old, according to reports from media outlets and obituaries.
This Cormac grew up with a literal front-row seat to show business. Being the child of a household-name actor means you’ve probably met half the working actors in New York and L.A. at some point—if not at work, then at dinner.
It’s possible this Cormac Dennehy is the same one who ended up at Gersh. But there are no official profiles or statements confirming they’re the same person. There’s been speculation in entertainment circles since the timing and the career path would fit, but nothing totally confirmed.
Sorting Out the Confusion: Are They the Same Person?
So let’s break it down with what we know.
The entertainment industry’s Cormac Dennehy (Gersh Agency, Shiffley, Bandier Program, SoundCloud) is a known quantity. People in music and TV know him as a manager, a former student of the Bandier Program, and maybe even as Brian Dennehy’s son. His ties to Syracuse and New York run deep, which match up with a likely entertainment upbringing.
On the other hand, the Cormac Dennehy who’s an Education Manager for Medical Imaging in Vancouver works in a field that’s completely different. His LinkedIn and professional accounts don’t hint at any connection to show business or the Dennehy family.
Of course, it would be a decent plot twist if the same person led both lives. But after comparing the locations, job histories, and public profiles, they appear to be separate people who just happen to share a name.
That’s a classic search engine problem—not everything with a matching name connects to the same biography.
Why the Mix-Up Matters—And How to Keep Them Straight
You might ask: Why spend this much effort sorting through people with similar names?
If you’re a reporter, hiring manager, or even a casual networker, things like this can trip you up. Public figures who share names often see their stories mashed together, with job titles and family relationships incorrectly linked.
When you dig for information about Cormac Dennehy online, you’ll see references to healthcare articles, indie band gigs, and quotes in Broadway news. If you’re not careful, you might assume he’s an actor’s son by day, hospital executive by night. It turns into a quick game of “which is which?”
One trick is to cross-check locations and industries. Gersh Agency is in New York and Los Angeles, working with artists and creative projects. Vancouver Coastal Health is—well—up in Vancouver, working with hospitals.
Another way to keep things accurate: look for context clues in news stories or professional profiles. Is the Cormac Dennehy you’re reading about from the music world, or does he have a background in health sciences? Is there a mention of Syracuse University or a Canadian medical institution?
And if you’re reaching out for business or networking, send your messages to the contact that fits your field. The last thing you want is to send a talent pitch to a hospital HR office, or career advice to a talent agent by mistake. If nothing else, it’s a fast way to get ignored.
By the way, here’s a useful tip: if you’re ever running a search for a business contact, sometimes business media sites (like Big Business Bite) are quicker to provide the basics—like job title and industry—so you’re not sifting through five “John Smiths” in ten different roles.
The Takeaway—Not All Cormac Dennehys Are Alike
So here’s where we land. If you’ve come across the name Cormac Dennehy, double-check which one you’re looking at. The manager at Gersh Agency bridges music, branding, and possibly has family ties to the late Brian Dennehy. If you notice mentions of Vancouver healthcare, medical imaging, or Canadian credentials, you’re looking at a completely separate professional.
The mix-ups here show how easily a unique name can be dragged in two directions by the internet. Some news sites connect the actor’s son with the agent, while others highlight the healthcare expert. Unless someone puts out an official statement, assume they’re separate people.
If you’re networking or trying to get in touch, be sure to use the right contact info and keep your industries straight. You’ll look smarter, stay out of awkward email threads, and maybe even land the right meeting.
The story of Cormac Dennehy—really, stories—keeps going. One works with bands and actors. The other helps hospitals run smoother. Both are making an impact, just in completely separate ways.
