The Profession
"Respiratory Therapists keep the world breathing.
It's time your exam prep reflected that weight."
— Caleb Littlejohn, CRT · Founder, TMC Prep
🫁
RT is the fastest-growing Allied Health profession
Demand is rising. Your credential matters more than ever. The RRT designation is the standard employers and states are moving toward.
🏥
3 attempts. Then a 120-day wait.
The NBRC doesn't offer unlimited chances. Pass with preparation that reflects the actual clinical weight of the exam — not generic Q&A.
🤝
You need a community, not just content
The RTs who pass aren't just smarter — they're connected. TMC Prep is building that community.

RTs Who Passed.
In Their Words.

★★★★★
"The only platform that felt like it was written by someone who actually works in the ICU. Dr. Ventus explained vent troubleshooting better than any textbook. Passed high cut on my first attempt."

"Failed the TMC twice with other platforms. TMC Prep's domain breakdown and AI tutor finally made ABG interpretation click. Third time — high cut."

"The live protocol feed alone is worth it. Found out about the NBRC 2027 transition changes a month before my program told us. That kind of intelligence matters."

The Community

Built to Pass the Exam.
Built to Last Beyond It.

TMC Prep isn't just exam prep. It's the beginning of the Emberline Medical Community — connecting RTs, physicians, and allied health professionals around a shared conviction: the people closest to the patient deserve the best intelligence in the world.

When you pass the TMC through this platform, you don't graduate out — you go deeper. CEUs, advanced resources, clinical case discussions, career opportunities, and a medical ecosystem built end to end.

Why We Built This

An RT Built This.
For Every RT.

Every question on this platform was written or reviewed by someone who has actually managed a ventilator at 3am, interpreted the ABG, called the physician, and documented the intervention. Not an algorithm. A working RT.

The existing TMC prep platforms treat respiratory therapy like a trivia game. We treat it like what it is: a clinical discipline with life-and-death stakes that deserves preparation built by people who understand those stakes firsthand.

"I built TMC Prep because when I was studying for my boards, I wanted something that understood what I actually do. I couldn't find it. So I built it. Win or lose — I honor the process."
— Caleb Littlejohn, CRT · Founder
