IN PLAY: Mark Gallegos, CPA, MST
Guided by a forward-thinking mindset, this leading tax expert channels his passion for
knowledge sharing to teach, connect, and elevate the profession.

Tax season just ended, and a 20-something Mark Gallegos, CPA,
MST, was celebrating with a week of surfing with friends in North
Carolina’s Outer Banks. One morning on the trip, he paddled into the
Atlantic where he would encounter a trauma only a small percentage
of the world’s population ever experiences: a shark attack.
“I felt something hit the board, and it dragged me under, thrashing
me around,” Gallegos recalls. “It felt like it was happening forever,
but it was really just a matter of seconds—then, all of a sudden, it
let go.”
Fortunately, Gallegos’ board got the brunt of the attack, and he
only ended up with stitches on both sides of his hand (the scars
are still present to this day). Interestingly, the most shocking part of
Gallegos’ story isn’t the shark attack itself, but what happened next:
He went back out in the water the next day.
“I knew if I didn’t, I’d never go back,” Gallegos says. “I couldn’t let
that fear stop me—I had to keep moving forward.”
That mindset has long guided Gallegos’ personal and professional
life, helping him stay positive and come up with the best solutions
for whatever challenge was at hand. It’s a trait that’s served
Gallegos well in his 20-plus-year tax career: “Tax is really about
people making decisions under uncertainty—it sits right at the
intersection of business, law, timing, and human behavior.”
Gallegos, who currently serves as a tax partner at Porte Brown
LLC, believes his career is less about calculations and more
about judgment, perspective, reading the room, and emotional
intelligence—all skills that have transferred into what he describes
as the core part of his professional purpose: knowledge sharing.
“For me, knowledge sharing is the most powerful thing that’s out
there,” Gallegos says. “As tax professionals, we’re involved with
someone who’s building or selling something, or maybe navigating
a very stressful transition—being invited into those moments is a
big responsibility that I’ve always taken very seriously.”
His commitment to knowledge sharing has led Gallegos to become
a sought-after public speaker at tax and accounting conferences
across the country and positioned him to serve as a trusted media
expert, where he regularly shares his expertise with various news
outlets, including Bloomberg, USA Today, The Wall Street Journal,
and others.
Though, despite his prevalence in the media and numerous public
speaking engagements, it didn’t always come easy to him: “When
I’d speak publicly in college, I was nervous, like where your heart
feels like it’s going to jump out of your chest. Even after college, I’d
do these lunch and learns at my firm that felt nerve-racking.”
Over time, Gallegos found the key to overcoming his nerves was
to always be well prepared. He recalls a time when he was asked
to do a “small talk” in Las Vegas: “It wasn’t a small talk, it was a big
talk; I was really, really nervous, but I came prepared.”
In that moment, Gallegos realized that by sharing his expertise with
an audience, he had the opportunity to teach, connect, and make
an impact: “I had the platform, the microphone, and people were
listening—whether they agreed or not. When I was done, I realized
it wasn’t that bad, and I really enjoyed it.”
What began as a challenge has evolved into a passion, fueling his
drive to share knowledge and connect with audiences wherever
he goes: “It’s almost like a craft where I just want to keep practicing
it. No matter who’s in the room, I get fired up to go and speak. I’m
always hoping there’s a chance to inspire someone or give them
something to walk away with.”
For others looking to be seen as thought leaders in the profession—
whether on stage or in the media—Gallegos says the best place
to start is by writing and getting more involved: “No one’s going to
take you seriously if they don’t think or know you have a message
that’s relevant and coherent.”
Being a longtime active member of the AICPA and the Illinois
CPA Society (ICPAS), Gallegos is no stranger to professional
involvement. In fact, he’s been a dedicated ICPAS media expert
for several years now and is beginning his first year on the ICPAS
Board of Directors this spring. For him, it’s a chance to give back
to a profession that’s given him so much: “It gives me a voice to
say how we should keep moving this profession forward. We’ve all
benefited from it, we all continue to benefit from it, so how do we
inspire others to want to come into it and do the same thing but
even bigger and better?”
As Gallegos embarks on his new leadership role, his commitment to
advancing the profession echoes back his belief in facing fears head
on and moving forward: “My hope is that people will continue to walk
away believing that a meaningful career in accounting isn’t about a
perfectly planned path—it’s about curiosity, courage, generosity, and
being willing to grow even when it’s uncomfortable.”
