🌟 LAST BUT CERTAINLY NOT LEAST! 🌟

Introducing Diamond H third and final AQHA World Show competitor… I COULD BE DANGEROUS, aka MORGAN! ❤️🐴

I can’t even begin to tell you how excited I am to be showing this special boy at the AQHA World Show!

Morgan is my homegrown, mushy, absolute favorite kind of horse! ❤️ From the day he was born, he has held a special place in my heart, and getting to be the one to swing a leg over him and show him on this stage makes it that much sweeter.

After a successful show season, I’m so excited to head to Oklahoma City and see what we can accomplish together!

Morgan and I will be competing in:

⭐ Level 1 & 2 Junior Ranch Riding

⭐ Level 1 & 2 Junior Ranch Trail

⭐ Level 1 Ranch Riding Stakes

⭐ Level 1 Ranch Trail Stakes

Some horses are just special, and Morgan is one of those once-in-a-lifetime kinds of horses for me. He makes me smile, makes me laugh, and reminds me every single day why I love what I do.

Every day with this horse is a blessing, and every ride is an absolute joy. ❤️

No matter what happens in the show pen, I already feel like a winner just getting to call this boy mine!

Oklahoma City, here we come! 🏆

🌟 AQHA WORLD SHOW – COMPETITOR #2! 🌟

Next up representing Diamond H at the AQHA World Show is the beautiful CHILLY RUN! ❤️

We are so excited to have Ashley Posthumus back in the saddle showing this gorgeous mare in the Level 1 & 2 Amateur Ranch Riding!

But what I’m REALLY excited about is seeing Ashley and Halley back together under the Friday night lights for the Ranch Horse Competition! 🌟🐴

Now, we’re hoping for just a LITTLE less excitement from Halley this year… and maybe we can keep ALL FOUR FEET ON THE GROUND! 🤣🙈

IYKYK! 😆

Halley will also be hitting the show pen with Heather Thompson in the:

🏆 Level 1 & 2 Junior Ranch Riding
🏆 Level 1 Ranch Riding Stakes

We can’t wait to see what this talented mare and her riders can accomplish in Oklahoma City!

Let’s go, Team Diamond H! 💎🐴❤️

🌎🏆 AQHA WORLD SHOW… HERE WE COME! 🏆🌎

We are officially just 3 DAYS AWAY from move-in day at the AQHA World Show in Oklahoma City! 🤩

Over the next few days, we’ll be introducing the teams representing Diamond H Training, and we’re kicking things off with a duo that knows how to SHOW UP when it counts! 💪

✨ ASHLEY POSTHUMUS & METALLIC CHILLY ✨

This talented team will be competing in:

🐴 Level 1 & 2 Amateur Working Cow Horse
🐴 Level 1 & 2 Amateur Ranch Riding

One thing I can always count on with these two is their ability to rise to the occasion! They work hard, stay focused, and when the pressure is on, they have a way of stepping up and getting the job done.

I am so excited to watch this team walk into the World Show pen and do what they do best! They’ve put in the work, and now it’s time to go have some fun and let it all come together! ❤️

Ashley, let’s go make some memories in OKC! 🏆🔥

✨ FIRST IMPRESSIONS MATTER! ✨

One of the compliments I receive most often isn’t necessarily about how my horses perform. It’s about how they LOOK.

“How do you get your horses so shiny?”
“They always look so healthy!”
“I love your saddle pads!”
“You guys always look so put together!”

And let me tell you, those compliments mean more to me than people probably realize. ❤️

I’ve always believed that walking into a show pen is a lot like walking into a job interview. You should show up looking like you WANT the job!

Your horse should look his best. YOU should look your best. From the shine on their coats to the saddle pads, shirts, and overall presentation, it all matters to me.

Does a pretty saddle pad make a better horse? Nope. Does a fancy shirt win a class? Absolutely not.

But presentation reflects pride. Pride in your horses, pride in your work, and pride in the program you’ve worked so hard to build.

It’s not about having the most expensive equipment or the fanciest clothes. It’s about taking care of the little things, because those little things say a lot about you.

At Diamond H Training, I want my horses to look as good as they feel, and I want our presentation to reflect the effort we put in behind the scenes every single day.

The performance should speak for itself, but the first impression happens before you ever make your first maneuver. 💎🐴

🤩 WOW—WHAT A WEEK IN DES MOINES! 🤩

We had an incredible week at the Iowa Quarter Horse Show & RHF! First off, the facility is absolutely STUNNING after its renovation—hands down one of the cleanest, nicest facilities I’ve ever shown at. And the Iowa Quarter Horse members could not have been more friendly and welcoming. ❤️

Day 1 started with AQHA Ranch Riding, Ranch Rail, Reining & Trail—and all three horses showed up!

🌶️ Chilly Run
🥇 1st — L1 Ranch Riding with a 77.5
🥉 3rd — Ranch Reining
✨ Top 10 — Ranch Trail

⚡️ Electric Feelz
✨ Top 5 — Ranch Rail
✨ Top 10 — Ranch Riding
And a great schooling run in Ranch Reining!

💖 Spontaneous Spark
Spark schooled beautifully in Ranch Rail and Ranch Riding, getting ready for the RHF the following day…and that preparation definitely paid off!

Then it was time for the RHF, and both Spark and Electric Feelz had a BIG week!

⚡️ SPONTANEOUS SPARK ⚡️

Spark started off with a 6th-place finish in RHF Ranch Trail, earning his FIRST PAYCHECK—over $900! 💰 He also placed in the IRHA for another $140!

Then came Ranch Riding…

Because of the rain, Spark had been sitting in his stall for about 4–5 hours and went in with ZERO warm-up. I honestly couldn’t have asked for more from him. He walked into that arena completely honest, focused and listening to me every single step.

He earned a 228.5, even with 3 penalty points from hitting a log!

🥉 3rd in the RHF Ranch Riding
🥈 2nd in the IRHA
💰 Around $1,500+ in RHF earnings, plus additional IRHA money!

Then it was on to Ranch Ideal, where Spark made the finals and finished 12th overall in an incredible group of horses. Just outside the money—but definitely ☝️ in my ❤️.

More than any placing or paycheck, Spark showed me something this week: HE WANTS TO BE A SHOW HORSE.

Every single time I walked into the arena with him, he was 100% with me. He listened, trusted me and made my job so incredibly easy and FUN.

I’m truly blessed to get to train and show this most perfect Barbie Prince. 👑💖⚡️ I am SO excited about his future!

⚡️ ELECTRIC FEELZ ,JESS and Heather ⚡️

These 3 had an incredible RHF!

✨ RHF Ranch Trail — 6th Non Pro & 8th Open
✨ RHF Ranch Riding — 8th Non Pro & 6th Open
✨ Open Ranch Ideal — 8th in a VERY salty class full of exceptional 4-year-olds!

But my PROUDEST accomplishment for Ellee and Jess came in the RHF Cow Work. 👏🏼🐄

Cow work is brand new to BOTH of them—they’ve only been working on it for about FOUR WEEKS—and they walked in there and earned a 4th-place finish! 👏🏼👏🏼👏🏼

That one made me incredibly proud. This is just the beginning for these two in this discipline, and I cannot wait to see where it takes them!

💰 Electric Feelz finished the week with just over $2,600 in total earnings!

What a week. What a group of horses. ❤️

I’m coming home incredibly proud, grateful and excited about what’s ahead. These horses showed up, tried their hearts out and reminded me exactly why I love doing this so much.

Des Moines, you were GOOD to Diamond H Training! 💎🐴❤️

09/27/2026

More to come later on all the accomplishments from Diamond H Training in Iowa… but first, I have to make a special post about one extremely special horse. ❤️

3-year-old Spontaneous Spark ⚡️ “Spark”

This week, Spark showed me that he doesn’t just have the talent—he wants to be a show horse. And that might be what makes me the most excited about his future.

First, let’s talk about his penalty-free Ranch Trail performance. 🙌 This young horse walked into the pen, handled his job, and earned himself his first paycheck of the week! 💰⚡️

For a 3-year-old, I couldn’t have been more proud of the way he stepped up and showed me just how much confidence, try, and maturity he’s gaining. All the work we’ve put in at home is starting to come together in the show pen—and Spark made it pretty clear that he is ready for this.

And Ranch Trail was only the beginning… 😉⚡️

“On behalf of myself and all the other small breeders to whom you afford this opportunity, thank you.” ❤️

I’m so excited about the future of this c**t, Shakkin Not Stirred, aka Casino
007 × Lite Of Hollywood 🖤

Casino is headed to Florida! 🌴

Selling horses privately from Amarillo can be tough, so I’m incredibly thankful for the prospect sales that give small breeders like me the opportunity to showcase the horses we’ve raised—while allowing me to keep them here, show fit them, and present them online until sale time.

Raising these babies is truly one of my greatest joys. ❤️ Watching them grow from babies in my pasture, developing their personalities and talents, and then seeing them move on to great programs where they have the opportunity to prove themselves is pretty darn special. 🥹

Best of luck to the new owners of this fantastic c**t! I can’t wait to follow along and cheer for Casino as he starts this next chapter. 💙

Thank you to everyone involved in providing these opportunities for breeders like me. It means more than you know. 🙏

Got lead changes? 😍🔥

Shakkin Not Stirred, aka Casino
007 × Lite Of Hollywood
(Hollywood Tinseltown × Grays Starlight)

I seriously just drool over this yearling. 🤤😍 His natural ability is 🤩! He is so feely, athletic, and everything just seems to come so naturally to him.

And to top it all off, he is an absolute sweetheart. ❤️ The kind that makes you excited about his future every single day.

Casino, you are one SPECIAL boy. 🥰🔥 I cannot wait to see what the future holds for this one!
