What's the CO2?

Registered dietitian Allison Knott has spent her career helping everyday athletes eat well, and she says the protein craze is crowding out the rest of the plate. In this episode of What's the CO₂?, she talks about why protein is in everything from cereal to ice cream, why she calls herself a "supplement skeptic," and what to look for before you trust a label.

Allison also gets personal. She talks about the three years it took to rebuild her strength after back-to-back pregnancies, why the "six-week" recovery expectation doesn't match reality, and what that experience taught her about the clients she works with. Along the way, she explains why food is more than nutrition and how a meal can be both physically and mentally satisfying.

We also cover:

• Why a dietitian still serves frozen pizza some nights
• How GLP-1 medications are changing nutrition, and why lifestyle still matters
• Gut health and her biggest takeaway: eat more fiber

Worth Fighting For | Gail Grimes, RN

What does it actually take to hold a hospital accountable, and what happens to the people who choose to try?

In this episode of What's the CO2?, we sit down with Gail Grimes, ICU nurse, nurse educator at Des Moines University, and a leading voice in the fight to unionize nurses at UnityPoint Health in Des Moines.

Gail takes us through her path into healthcare, from three generations of summer camp roots, to a soul searching study abroad trip in India that sparked her interest in medicine, to the ICU floors of Des Moines during one of the hardest stretches in modern healthcare history. She opens up about the patients who never left her, the emotional weight of critical care, and the moments that made it all worth it.

Then the conversation turns to what's happening right now: the push for safe staffing ratios, the fight for union recognition, and why nurse density, not good intentions, is what actually moves hospitals to change. Gail breaks down what a union really offers, why Iowa lags so far behind neighboring states, and why she believes this fight is bigger than pay, it's about dignity, accountability, and better care for everyone who walks through hospital doors.

Honest, hopeful, and grounded in a decade at the bedside, this is a conversation worth your time.

In this episode of What's the CO2?, Matt sits down with childhood friend Sergio Gonzalez, Head Football Coach and Athletic Coordinator at Sam Rayburn High School in Pasadena, Texas. From playing on a historic undefeated Galena Park team to building programs from the ground up at Chavez and now Rayburn, Sergio opens up about the journeyman years, the instability that comes with coaching, and what it took to earn a community's trust.

The conversation takes a serious turn as Sergio recounts suffering a heart attack on the sideline just weeks into his first season at Rayburn and the wake-up call that followed, including a 50+ pound weight transformation and a completely new relationship with health.

Sergio also shares his work as a founder of the Hispanic Texas High School Football Coaches Association, why representation matters to the kids he coaches, and his mission to challenge outdated stereotypes about Hispanic-led programs in Texas football. The episode closes with a candid reflection on loyalty, moral compass, and what it really means to do right by people, no matter what side of anything they're on.

A conversation about resilience, representation, and what it takes to build something that lasts.

Dr. Raquel Relph just finished residency and is stepping into her first year as a family medicine physician, but getting there wasn't a straight line. In this episode, she opens up about missing her first shot at med school over a forgotten laptop charger, her years as a CNA in hospice care (including caring for a 104 year old Holocaust survivor), and the brutal stretch of residency where she worked 57 of 61 days as chief resident. She also shares the hardest night of her career, the loss of an infant despite doing everything medically possible, and what it taught her about grief, connection, and showing up for people at their worst.

Dr. Relph will be practicing family medicine at the Iowa Clinic in North Waukee starting this fall.

In this conversation:

• Why one summer in Puerto Rico cost her an entire year before med school
• What DO vs. MD actually means, and why she chose the DO route
• The chaos and emotional toll of Match Day
• Her CNA years in hospice care, and what it taught her about dignity and death
• The hardest stretch of her residency, and how she got through it
• Losing a patient despite doing everything right
• The difference between hospice and palliative care
• Why she believes primary care is the most undervalued relationship in healthcare

Autism diagnoses have climbed from roughly 1-in-88 to 1-in-31 kids, but is that a crisis, or just better fishing? In this episode, I sit down with Dr. Nate Noble, a developmental-behavioral pediatrician and clinical geneticist who helped build Des Moines' developmental pediatrics practice essentially from scratch.

Dr. Noble pulls back the curtain on what a real autism evaluation looks like (spoiler: it involves bubbles, thrown toys, and firing his staff on command), why he believes medicine needs two more required courses, magic and sales, and why "levels" of autism matter less than most parents think. We get into:

• Why genetics "loads the gun" but environment "pulls the trigger", and why chasing a single environmental cause usually does more harm than good
• The real reason autism diagnoses have tripled in a generation (hint: it's not what you think)
• The three things Iowa's most vulnerable families actually need, and why he says it bluntly, even knowing it'll upset people
• What it actually means to give a family "irresponsibly optimistic hope," and why he's never once had someone ask for a refund on it
• His own pioneer spirit path from a Northwest Iowa farm to building a specialty that didn't exist yet in this state

Whether you're a parent navigating a wait list, a clinician who wants to communicate better, or just someone who appreciates a doctor who tells it straight, this conversation will change how you think about diagnosis, hope, and what "success" really means.

For years, Jessica Fraser tried to be the perfect chameleon at work, bending herself into whatever her job needed her to be. It worked, until it didn't. In this episode, she opens up about the moment she stopped stuffing her real self into a "neat container," took the leap to start her own company, and learned to see failure as fuel instead of something to fear.

Jessica is the founder of ElucidCX, a company she started just over a year ago that helps businesses make better decisions by having real, one-on-one conversations with their customers, turning qualitative insight into quantitative data companies can actually use. She's also a mom of five, a Woodlands, TX native, and a longtime friend of mine from my church days back in Texas.

In this conversation:

• Why she used to describe herself as "miswired" and what she realizes now
• The humble confidence it takes to bet on yourself
• Building a business while raising five kids
• Why failure became something she needed, not something she feared
• Growing up in The Woodlands and the community that shaped her

Zane Chapman had no guarantees it would work. Just a conviction that coaching throws was what he wanted to do with his life, and the willingness to take an unpaid volunteer job to prove it.

That decision took him from Eastern Illinois University to a volunteer position at Wisconsin, working alongside an Olympic discus thrower, to Drake University, where there was no throws program at all. Zane started with a pole vaulter, a soccer player, and a football player who'd never touched a shot put, and built it into a program with All-Americans and national qualifiers.

But this episode isn't just about what he built. It's about what he carried while building it.

Zane and his wife walked through two miscarriages before their "miracle baby." He spent years trying to help his lifelong best friend, Aaron, fight his way out of addiction, and still lost him far too soon, at just 30 years old.

This conversation is about a simple, hard truth: life is going to hand you hardship no matter what path you take. So why not spend it chasing something you actually love?

We talk about betting on yourself before you have any proof it'll pay off, what it's like to coach an Olympian, the emotional weight of loss and grief, and what it really means to define success on your own terms.

What does it take to lead a 23 year old nonprofit through its next chapter, while honoring everything the founder built before you?

In this episode, I sit down with Emmanuel (Manny) Caraballo, Executive Director of Freedom for Youth, a faith based nonprofit serving at risk youth in the Des Moines metro. Manny's path here wasn't a straight line, Army chaplain's assistant, youth pastor in Wisconsin, Illinois, and Northern Virginia, before landing in Iowa just nine months ago to step into the role left by founder Mark Nelson.

We talk about:

• Why succession planning is the thing most nonprofits (and churches) struggle to prepare for
• The three barriers at-risk kids face most; identity, skills, and access
• Why Freedom for Youth operates on "hand ups, not handouts"
• How teaching kids to cook, budget, and build is changing their trajectory
• The Eugene Lang story and why belief might be the most underrated resource in youth development
• What's next for Freedom for Youth, including their new construction project on campus.

If you've ever wondered what it looks like to invest in one kid at a time, and why that's the whole point, this conversation is for you.

Travis Shelton is a financial coach, founder of Shelton Consulting, and host of the Meaning Over Money podcast. But his path here wasn't straight — it ran through a job loss at the height of the 2008 financial crisis, $236,000 in debt, and an involuntary move back to Iowa three days into his engagement. What came out of that season was a completely different philosophy about money, work, and what it actually means to win.

In this conversation, Travis breaks down the difference between being wealthy and being rich, why the most financially fragile people are often the ones who look the most successful, and why he eventually walked away from managing billion-dollar portfolios — taking a 90% pay cut — to serve people in a more meaningful way. If you've ever felt the pressure to keep up, this episode is for you.

What does it take to leave everything you know behind, and then figure out who you actually are when the thing that defined you is gone?

In this episode of What's the CO2?, Matt sits down with Ross Moffat, therapist, soccer coach, and Glasgow native, for a raw, wide-ranging conversation about identity, mental health, and what it really means to grow up.

Ross shares his journey from the streets of Clydebank, Scotland to the Scottish Premier League at 16, then a leap of faith to Des Moines, Iowa with a couple hundred bucks and a soccer dream. But the more compelling story is what happened after the soccer stopped, and how long it took him to realize he'd never truly left it behind.

This Episodes dives into:

• The adaptation triangle: safety, belonging, and significance, and the behavioral drivers we develop as kids that quietly run our adult lives
• Why athletes are especially vulnerable to identity collapse when their sport ends
• The overscheduling and early specialization crisis in youth sports
• Why men wait until crisis hits to seek help, and what therapy actually looks like
• The "software update" model of self-awareness (not a reset, just an update)
• Jason Wilson's work on masculinity and what it means to be "the man the moment demands"

Ross brings both the lived experience and the clinical lens. This one goes deep.
