The Founders

A Veteran and an Olympic Torch Bearer Walk Into a Chiropractic Office and Take It Over.

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: find the root cause. Fix it. Tell you the truth — even if the truth is you don't need them.

Prime Spine Wellness has served Fort Worth for over twenty years and holds a 5-star rating on Google. 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."

Parking Lot — cinematic poster of Dr. Mac in police uniform meeting the chiropractic recruiter who would change his career

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."

Body of Evidence — Dr. Mac in clinical lighting studying X-rays and monitors, subtitle I studied kinesiology like I was trained to understand threats

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."

The Karate Kid: The Clinic — Dr. Mac mentoring a young patient through an adjustment in a cherry-blossom dojo setting

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."

The Husbands — comedic ensemble poster of reluctant husbands finally arriving at the chiropractor with their wives

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.

It Was a Chiropractor Who Got Her Back to Her Life

"The medical field kind of wrote me off."

The Second Opinion — Dr. Abi in a lab coat holding a glowing pelvic-bone hologram in front of medical monitors, blue clinical lighting

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."

The Interpreter — Dr. Abi adjusting a patient on her Ghana chiropractic mission trip, warm golden-hour cinematic poster

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."

ABI — Dr. Abi in glasses peeking through a doorway into a colorful office with a spine model and candy jar; subtitle reads She has multiple ways of changing people's lives

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."

Nine Months — Dr. Abi performing a prenatal chiropractic adjustment on a pregnant patient, movie-poster style

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."

Torch Bearer — Dr. Abi carrying the Vancouver Olympic torch on January 15, 2010, the day before her chiropractic-school journey began

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."

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 been here for over twenty years. It has a 5-star Google rating. It's run 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.
