The Diamond K Training Program
Every Diamond K horse is developed through a deliberate, hands-on program designed to prepare them for real-world riding in every sense. Our horses are systematically trained across multiple western disciplines — from ranch riding fundamentals to advanced reining maneuvers — and are intentionally tested in a wide range of environments and scenarios. Each horse is exposed to new settings, obstacles, terrain, and pressure situations to evaluate their mindset, responsiveness, and reliability. This process ensures that every Diamond K horse is not only talented, but also a safe, confident, and trustworthy partner no matter where the ride takes you. We welcome you to spend time with us at the ranch and experience firsthand the personal investment and care behind every horse we produce.

What Our Clients Are Saying
Kevin and his wife were so nice and hospitable. I felt like I was coming home.. After driving 10 hours and being able to come and ride for 3 hours at their facility, it was truly a great venue I was able to ride numerous horses and finally settle in on one of the prettiest sorrels. I’ve seen he was a spooks got a gun sire. I teased Kevin that it was as good as riding in a Maserati. I look forward to buying another horse from Kevin and his wife soon. I’m excited about the new chapter with this horse and being able to show him on the East Coast

I first contacted Kevin about a few horses he had going to auction in late 2021. He asked me what I was looking for and directed me to a few geldings he believed would work well for me. He also lead me away from one of his horses that he didn’t think would be a great fit, which I appreciated. I had dozens of questions for Kevin when I finally found my favorite, Tinsel. Kevin took time and care to answer ALL my calls and texts. When my husband and I made the trip from California to Ohio to meet Kevin and Tinsel, and attend the Horseman’s Mission Auction, I knew I’d made the right choice in horse and trainer. Tinsel was everything Kevin promised he’d be, and then some. I couldn’t be happier! Thank you, Kevin and Marybeth for helping me find my forever horse.

I bought Rusty through Premier Online Sales. In speaking with Kevin and discussing what I do and was looking for this gelding sounded like an exact fit. Buying a horse in an online auction without actually seeing and riding them in person is a gamble. But I knew buying from Kevin this would not be an issue. Rusty is everything that Kevin said he was. I would buy another horse in an online auction from Kevin in a heartbeat. He was also great in arranging transportation all the way to Tucson, Arizona. Thanks so much! You do an amazing job with your horses!

Kevin and Mary Beth are the hardest working, most honest couple in the horse business. They have helped me buy and sell horses over the past 3 years I couldn’t say enough good things about them.

Thanking my lucky stars to find Kevin and Mary Beth Raber and their integrity filled Diamond K Horses personalized operation as I recently decided to introduce my grandchildren into my world of horses! 48 years ago, I was finishing up a nationally ranked AQHA Youth Activity run on an amazing versatile Wimpy bred QH specializing in horsemanship, reining and Western riding. I stopped horses when he passed at 35 years old and didn’t see a path forward to include them into my life. Fast forward to the current day with respectful & humane training techniques! I was delighted to find trainers like Kevin achieving consistently good minded, well broke, versatile, trustworthy happy horses-a long dream come true! I also found a genuine desire in Kevin to make a good “fit” for this “Gigi” and my “grands” and patiently and respectfully helped me gain my confidence back as I purchased my 1st perfect boy at an on-line sale and then my 2nd by going to his beautiful facility and riding available horses there. The horses that Kevin have fitted for us and represented to us are just as he carefully describes them to be. Whether this Gigi ever shows again,(or helps the grands do so), freely rides the trails, or simply builds trust and friendship on the ground with these loving gentle giants, I have support, guidance and forever friendship with Kevin, Mary Beth and all who are the character driven staff at Diamond K Horses🐴❣️ My heart is full…and so are my muck buckets😂

It is very easy for us to recommend Kevin Raber and Diamond K Versatility & Family Horses. We reached out to Kevin via text and phone, watched his videos, and he helped us throughout the entire process. We bought our beautiful, buckskin, forever horse, Herman, via MM Auction Services at the Best of Texas Premier Horse Sale. He has been everything we expected and more! Kevin‘s descriptions and write-up for the auction were accurate and thorough, and Herman is every bit the horse he told us he would be. Thank you, Kevin!

I purchased Ringo from Kevin this January at the triangle winter sale in Oklahoma. Kevin was so thorough in communicating with me on Ringo, his training his health and every detail. I honestly went to the sale to buy a another horse but after meeting Kevin and had already researched him I knew I wanted to buy a horse from him! His honesty, character, and amazing talents are hard to find in the horse industry! I will likely never buy a horse from anyone else. Thanks Diamond k for giving folks a safe place to buy nice horses! You have big fan in Texas:)

Dear Kevin, Marybeth and the Entire Diamond K Team, I wanted to take this opportunity to give you an update on our progress and to express, once again, our sincerest gratitude as we near the four-month anniversary of our winning bid at the Spring Horseman’s Mission Select Auction, on Huey, the beautiful 5-year-old Palomino gelding. This son of HF Mobster has been nothing short of magnificent, a beautiful, well-trained horse with a great personality! As you know from our many visits together over this past year, my daughter and I have spent several years looking for that once in a lifetime horse. Our search took us out west to Wyoming and Colorado, south to Texas and many points in between. All the while searching for that well trained, versatile horse experienced in reining and western pleasure that I could enjoy as I approach retirement. Even though there were times, we felt that the market might have put our ideal horse out of reach; you calmly and constantly assured us that you would find the right horse for us and within our budget. We are forever grateful that, after searching for reputable horse trainers all over the country, we found you and Diamond K! Your eye for horses is impeccable and once they come through the Diamond K Program they are truly world class. Your patience in getting to know us and matching us with the right horse allowed us to bid with confidence at the auction. We give thanks to the Good Lord that we found you and we are forever grateful for the time and care with which you guided us through the buying process. We simply could not be happier with Huey (aka “Trigger” as he’s known at our Barn.) After years of searching for the right trainer and the right horse, I would and do recommend you and the Diamond K Team to anyone who is looking for that once in a lifetime horse!! With our Deepest Gratitude,

We went to this sale skeptical of the unknowns you can find out about a horse after you have gotten home with him. My husband is a performance equine veterinarian. So obviously we scrutinized every horse at the sale. We met up with Kevin & Mary Beth with Diamond K and liked 2 of his horses. Kevin went out of his way to discuss, reveal anything, work with us on this horse. He went above and beyond. After a year of riding this beautiful horse, I can tell you that we know a lot of million dollar trainers and Kevin’s work with horses are in my opinion as quality as the big guys. I will always recommend Diamond K and go to look for my next purchases. 5 ⭐️ ‘s
Stephanie Fluitt
From exploring the prospect of purchasing my first horse in over 20 years to now a proud owner of 2 Diamond K horses, I can’t speak highly enough of the entire Diamond K team. From the initial informational conversation with Kevin and all the way through the purchasing process, Kevin was honest, helpful, and passionate that I found the perfect match and equine partner and that we got seamlessly set up to succeed! After purchasing the “ride of my life”, Kevin has been there for me every step of the way – no question is too big or too small. Different than your standard sales or buying experience, the team at Diamond K care that you and your horse go on to accomplish all of your goals together and have pride in the horses that graduate their program. Incredible people and even better horses, if you are lucky enough to buy a Diamond K horse, you will be thankful every day!

I met Kevin Raber at a sale I was attending. Not to buy a horse, but to learn and understand the process. I also wanted to determine what price range I needed to shoot for as well as to meet the trainers to discuss their horses. Kevin was very gracious with his time and I was very impressed with his horses. He told me to follow on Facebook as all the sale horses that came available were listed there and to contact him when I knew I was ready to start the process of looking for my horse. Many months passed as did many sales. I knew the time was right to contact Kevin and start the process. Based on what I wanted he advised me to look at 5 he had at the Best of Texas sale in 2021. He told me they were all horses that they had raised since weanlings and had been in their program the whole time. He also told me he had 2 finished show horses available to try as well. I made arrangements to visit their facility. Kevin and his wife Marybeth were amazing and welcoming. They listened to what I was saying in regards to what I planned on doing with the horse. They saddled every horse that was currently available to try and explained the pros and cons of each one. My decision was hard because they had 3 I really loved, but ultimately it came down to one. Luckily I was able to come away with him at the sale, only because Kevin made me a gracious offer in hauling him for me. This allowed me to have just that extra amount of cash I needed to win the bid. I wouldn’t have gotten him otherwise. Diamond K continues to help me with Chrome even 1 1/2 years later. Whether it is to send me the bit I need, to give me advice when I text to ask “what cue did you use for this”, or just to check in to see how it’s going. I can’t say enough great things about my experience. I feel like once I bought the horse, the relationship didn’t just end. They genuinely care that you reach your goals. Best of all my horse was as advertised.

Kevin and Marybeth are amazing. They let us come ride all of their horses and paid attention to exactly what we were looking for and even better attention to our skill level. They were very honest when representing their horses, even steering us away from some that we liked but they knew would not suit us well. They were patient with our requests and found us the PERFECT horse, “The Ride of our Life” we love Chubbs and the Diamond K family. Chubbs has found his FOREVER home and Diamond K always have a place to stay in CA!

Purchasing Jack from Diamond K was the best decision. The horse is amazing and Kevin has been there for all of my questions.
Blair Cummings
Kevin is extremely honest and enjoyable to work with. He truly makes sure you will be a good partner for the horse and is very open and honest about questions, ability, etc.
Ashley Tsaras
With the greatest of truths, Kevin and his brother Nathan have the best work ethics and undeniable abilities with horses and mules that I’ve ever witnessed. No gimmicks here real horsemen. I am proud to know them.

Dena Hartman
I bought Colonel at the Bots Sots Remount Sale. I spoke with Kevin about him before the sale and he is exactly how Kevin described him… exactly what I was looking for! Kevin was great about giving me advice on how best to get Colonel settled into his new home and answering any questions that I had. I would highly recommend Diamond K Training and Performance Horses to anyone! We love Colonel! Thanks Kevin!
Cindy Clark
Kevin was great to work with and answered every question I had on a horse I was inquiring about. I would highly recommend him to anyone looking for a horse of any discipline!
Jo Ann Merrill Reynolds
Diamond K was wonderful in finding my “forever” horse. From the first time I inquired about one of their horses I knew I wanted to buy a horse from them. Kevin always answered every question I had. He is not only very knowledgeable about horses, he was very kind and patient with me through the entire process. They truly want to find the right horse that suits each individual buyer. They were always open & honest with me about their horses and that meant everything to me. And….. yes they did find my “forever“ horse and he’s everything they said he was & I couldn’t be happier
The Baileys
I purchased my quarter horse grey gelding sight unseen from Kevin, as I live in New Brunswick, Canada. After a few chats with Kevin over the phone, I knew I wanted this horse. Kevin was so kind and helpful in getting me through the process of preparing for his long journey from Ohio to Eastern Canada. When my horse arrived, he was everything and more than I had hoped for. Such a sweet boy, well mannered and perfectly trained for my needs! Thank you Diamond K and to all those involved in making my dream horse a reality.
