Two Different Stories. One Very Different Chiropractic Office.
His path started in the Army and law enforcement. Hers started in nursing, pediatrics, pregnancy care, and mission work. Together, they created a Fort Worth chiropractic office built on honesty, comfort, and care that sees the whole person.
They met in a classroom in California. They didn't know it yet, but they'd end up married, raising kids in
Fort Worth, and running a practice together.
What they agree on: listen first, look closely, explain what they find, and build a plan that fits your life
— even if the plan is "you don't need us."
Prime Spine & Wellness continues a Fort Worth tradition of patient-first care that began more than twenty
years ago. Here's who's running it now.
Founder · Veteran
Dr. Donald "Dr. Mac" MacMullin
"I'm not a used car salesman. I'm not trying to sell people on anything. I'm just genuinely talking."
Army. Police. Parking Lot.
"It's not dramatic. But it got me here."
This isn't a touching story at all. But it's real.
I was a police officer. I was going to school. And I didn't know where I was going with my degree.
Before that I was in the Army. Three and a half years as an infantryman, with a deployment to Afghanistan.
After the military I went into law enforcement. Five years on patrol in New Mexico and Utah.
While I was still working as an officer, I got my Kinesiology degree at the University of Utah. I wanted to
understand how the body works and how it breaks down.
But I still didn't know what came next.
Then one day I was at school, pulling into the parking lot in my police car. This guy sees me getting out,
walks up, and starts talking to me. He was a recruiter for a chiropractic school. Around the same time, my
cousin's father-in-law — a successful chiropractor in California — started telling me I should look into it.
I needed a job that let me spend more time with my family. More flexibility. Chiropractic was the most
practical path forward without going backwards in my career. And I could keep helping people — just without
dodging bullets. I was basically guaranteed I'd go home every night.
It's not dramatic. But it got me here.
I went to Life Chiropractic College West in Hayward, California. Graduated in 2021. Came to Texas and trained
under some outstanding chiropractors.
Same Plan for Every Patient. I Watched It Happen.
"That's not why I got into this."
Early on I worked under a chiropractor where all that mattered was getting the patient signed up on some
generic plan. Maybe it didn't even work for them. I watched that happen and I hated it.
When we took over this practice, we made it different. We're not here to take advantage of people when they're
in pain.
It Felt Like a Therapy Session
"I built the opposite of every room I'd worked in for a decade."
The office doesn't feel like a clinic. It feels like someone's home. I realized recently — honestly it felt
like a therapy session — that there's a direct connection between that and my background.
As a police officer, I wasn't comfortable. I was on edge. Every environment I worked in for a decade was
designed for function, not people. So when we designed this space, I built the opposite. It's kind of a third
place — not work, not home. You're in my house. How can I help you?
People Tend to Feel Safe Around Me
"Empathy just came natural. Law enforcement sharpened it."
People tend to feel safe around me. That's not something I manufactured — empathy just came natural. But law
enforcement sharpened it. I know how to read a room.
I've had patients who were uncomfortable with previous doctors. I won't do things that might trigger someone.
I always communicate: if anything makes you feel uncomfortable, let me know and we can modify what we do. I
build connection with a person before I ever do anything hands-on.
The protector thing was always there. But what I really wanted was to help people deal with their issues.
Chiropractic lets me fix their problems instead of just showing up after something bad already happened.
I'm not trying to sell people on anything. I'm just genuinely talking. Which gets me in trouble — I take too
long with people.
Meeting Them Where They're At
"I don't try to change them. I just meet them where they're at."
Honestly, it's really typical for men to just not do anything about their health until they're basically
dying. Their wife's been telling them for months — you got to go here, you got to take care of this. They
never do until finally the wife schedules the appointment for them. So they show up with the wife. And I think
men can be more skeptical of being sold because it feels like someone trying to take advantage of them. I'm
acutely aware of that because I'm the same way. So I don't try to change them. I just meet them where they're
at, help them feel better, and if that's enough for them, awesome. If it's not, I'm not going to force it.
I'll just be available for them when they're ready.
I'm very introverted. That surprises people. I go home and I'm up till midnight, sometimes one in the morning,
working on patient files.
The first thing is probably kid sports. I'm at my kids' jiu-jitsu or baseball practices, games, tournaments.
If I'm all caught up, which is rare, we try to go camping or go fishing.
I watch college football religiously. USC is my team. I listen to the Peristyle podcast. High school games too
— if the game's good, I'll watch any level. I'm also a podcast guy. Drinking Bros is my favorite — it can be
an offensive one, but the whole point of that podcast is that no one drinks alone. It's a veteran podcast. I'm
not a huge drinker. I also listen to the Citizen podcast.
If you want to get me talking, start with any of that.
Co-Founder · Webster Certified
Dr. Abi Mitchell, Webster Certified
"The medical field kind of wrote me off. It was a chiropractor who helped me get back to my life."
It Was a Chiropractor Who Got Her Back to Her Life
"The medical field kind of wrote me off."
When I was in ninth grade, I broke my neck snowboarding.
I did all the sports. Soccer and gymnastics when I was really young. Basketball, volleyball, track, football —
American football — and water polo in high school.
I was doing two to three hours a day just because that's who I was.
The medical field kind of wrote me off. It was a chiropractor who helped me get back to my life.
She was a female chiropractor. Her name is Dr. Christy. She was my mom's chiropractor.
I kind of wanted to be a chiropractor after that. Back in ninth grade. But throughout my years I wasn't really
sure what I wanted to do.
So I ended up going to nursing school. While I was in nursing school, I also worked as a chiropractic
assistant for multiple chiropractors. I became a nurse and worked in a small town hospital. Got to see a lot
of different things. I fell in love with being in the room when babies were born. I knew I wanted to serve
moms and newborns.
Twenty Students Per School. Eighty in the Country.
"I didn't have a 4.0. That's what it took."
So I applied to become a midwife.
In Canada, midwifery is incredibly competitive. They take about twenty students a year per school. There are
about eighty spots in the entire country. I'd already been through nursing school and I didn't have a 4.0 GPA.
That's what it took.
I didn't get in.
I was really disappointed and sad.
He Could See I Was Upset
"Oh, don't be upset. You're going to be a chiropractor anyway."
I was working at Dr. Christy's front desk. I remember it was a Saturday morning. I used to work the Saturday
shift. Her husband came in. He could see I was upset.
He looked at me and said: "Oh, don't be upset. You're going to be a chiropractor anyway."
I was like — you know what, he's right. I can be a chiropractor and I can still see pregnant women and babies.
Just on a different side.
I'd worked as a chiropractic assistant for multiple chiropractors while I was in nursing school, so the world
wasn't new to me. But that conversation was the moment it clicked.
I left Canada and went to Life Chiropractic College West in Hayward, California. I graduated in March 2020.
During school I met my husband and became President of the Pediatric Club.
The mission trips changed me.
Before I went to chiropractic school, Dr. Christy had gone on a mission to Uganda with the same doctor who
runs the mission program. When he came back, he told my mom: "The best thing you can do for your daughter is
help her get on one of these trips. She's going to get her hands on so many people and be able to help and
serve." Dr. Christy told me the same thing — that I would learn more on a mission trip than I would in three
years of school.
They were right.
I went to Ghana first. A lot more people spoke English there compared to India. The people trusted us before
we even arrived. They were already waiting outside the gates before we even drove in the first day. They
didn't care as much about the explanation — they just wanted help. It was really good for us to learn how to
communicate on a third-grade level about people's health. That's the most important thing.
That lesson stuck with me. I still communicate that way with every patient — simple, clear, no jargon.
Educating the patient is super important, no matter what age. If you can't explain it so someone understands,
you haven't done your job.
Then I went to India. We had our own translator with each doctor. They were either medical students or people
who had been on the mission before and knew what was happening. I could explain things in English so they
understood how to translate it. Long days of teaching, learning, and adjusting people who had never
experienced chiropractic care.
Does This Feel Tight to You?
"I bring awareness to their body so they can feel what I'm feeling."
I don't just see a back. I see a person. I look at the body as a whole — muscles, ligaments, not just the
joint. You can adjust something as many times as you want, but if you're not figuring out what's actually
causing the problem, you're doing a disservice to that patient. And if I can't help you, I need to send you to
someone who can.
I talk a lot during first visits. I explain absolutely everything I'm doing. Before I do anything, I'll say,
hey, I'm going to touch your hips here. And then I touch. I'll say, does this feel tight to you? And I bring
awareness to their body so they can feel what I'm feeling. People are in a vulnerable state when they're
laying face down on a table and they don't know what's happening. So I make them participate in the
appointment rather than just lay down and let me do my job.
I Don't Know If It Was What You Did, But He Slept Through the Night
"He just recently brought the baby in on his own without mom."
I had a dad once — first-time parent, skeptical. His wife was the one who wanted to bring the baby in because
he was having colic. They were exhausted. You can usually tell how comfortable people are based on how much
they hover, how close they stand. For that dad, I said — why don't you lay on the table and let me put baby on
top of you, tummy to tummy. He felt more a part of the process that way.
He came back the next visit and said, well, I don't know if it was what you did, but he slept through the
night. He was still skeptical for a while. But he just recently brought the baby in on his own without mom. He
was like, hey, can you see him? He's spitting up again.
I love those patients. The ones who aren't sure at first and then just kind of come around.
I'm a mom. I've felt what chiropractic does during pregnancy and labor in my own body. That changes everything
about how I care for the moms who come through our door.
From Serving on a Mission to Representing Her Country
"January 15, 2010. The day after my eighteenth birthday."
Before chiropractic school, I went on my very first mission trip to Uganda. When I got back and checked my
email, there was a notification — I'd been approved to be an Olympic torch bearer.
Back in high school there had been a challenge online where you logged your active minutes. I was playing so
many sports I was doing two to three hours a day without even trying. When you apply, you don't really know
where you're going to be or what day. They try to get you close to home. I had three days to get all my
paperwork in because I obviously wasn't checking email while I was in Uganda.
January 15, 2010. The day after my eighteenth birthday. I carried the Olympic torch for the Vancouver Games.
My dad is an avid runner. I went running with him to prepare because I had no idea how long I'd have to carry
it or how far I'd go. The torch weighs about fifteen pounds. It was one of the most incredible experiences of
my life.
I went from serving on a mission trip to representing my country — just by being active and doing the stuff I
loved.
Most people don't know I'm Canadian. Both of my parents are twins — I always throw that out as an icebreaker.
And when we found out about our surprise baby, we definitely thought it was going to be twins. Just as a cruel
little joke — going from three to five kids. Thankfully just one little firecracker.
Couches. A Dining Room Table. No Posters.
"You can talk to people and they'll understand a lot more."
My first office — Life Within Chiropractic — I catered towards moms and families. I had couches. I had a
dining room table that I'd sit at with patients for their first appointment. One big open space so moms could
see their kids playing while they got adjusted. That comfort vibe. When we took over this office, I really
wanted to keep that going. Nice comfortable chairs. No stiff waiting room chairs. No posters on the walls that
nobody reads. You can talk to people and they'll understand a lot more than reading off a poster.
When I'm not adjusting, I'm playing softball, rock climbing, running, or at my kids' sports. I was a super
athletic kid and now I get to be on the other side as the parent watching them grow and learn and develop.
That's how I recharge.
The Practice
They Met in a Classroom in California
"They bought Dr. Carter's practice and rebuilt everything."
Where It Started→Where It's Going
Mac and Abi didn't just build this practice together.
They're married. They met at Life Chiropractic College West in California.
In 2023, they purchased Hulen Chiropractic Clinic from Dr. Carter, who had served the Fort
Worth community for over twenty years. They renamed it Prime Spine Wellness and renovated the entire space.
Abi brought the design philosophy from her first clinic — the couches, the comfort, the home feeling. Mac
brought the need for a space where nobody has to be on edge. Together they created the practice they both
wished they'd found.
They have similar styles but they contrast in ways that serve patients better. Some people like the more
manual adjusting — that's Mac. Some people like it a little gentler — that's Abi. Some patients schedule with
Mac because he always gets their neck. Others schedule with Abi because she's really good at working the
muscles when their sciatica flares up. Patients figure out who they like for what, and Mac and Abi have no
problem with that.
Abi sees the pregnant moms, the babies, the kids — that's what makes her happy. Mac sees everyone else, and
he'll see kids and pregnant patients too if Abi's not available. They play to each other's strengths. They
don't compete. They complement.
And they don't just do chiropractic. Prime Spine has massage therapy, therapeutic ultrasound, and other tools
under one roof. Whatever you need to get better — they'll find the right approach.
We're not motivated by sales. We're motivated by helping people. Our main goal is to get you out of pain and
back to your life.
This practice has served the Fort Worth community for more than twenty years. It's run today by two people
who happen to be raising their kids in the same community they serve. And if you've been putting this off —
if you've been waiting for the right place, the right doctor, the right moment — this is it.
