- Jack joined his dad's dealership in 1970 and was quickly shown to be a natural in the automotive business. His success at building a wonderful family and business stems from an innate ability to make friends and positively influence those around him. His close relationship with the manufacturers has led him to having a unique perspective on the automotive industry. On his down time, he is an avid golfer and loves to travel. More than anything, he is proud of what Sill-TerHar has become, and values that his entire family is involved in its continued growth. He is pictured here with his wife Penny.Favorite Car:2003 Ford GT

Greg's a Broomfielder through and through. He joined the staff in 2002 as a manager and has become known for his gruff exterior, however most of us know that if you don't let it phase you, you ca get to his, nougaty center. As any well-versed leader, he commands respect and returns affection. He's a lot like Batman in that way. He loves the outdoors and his fifth wheel that takes "camping."

Shane started at Sill-TerHar in 2005. Growing up in Broomfield Shane used to look longingly at the great working environment that was Sill-TerHar and vowed that one day he'd be top salesman there. Little did he know that was not to be, so he became a manager. Also, interesting side note, he went to middle school with my wife, but you don't know me... so maybe that's just interesting to me.
- Adam Wilson
- Mazda Sales Manager
- awilson@sthmotors.com
Adam joined us in 2024 in Lincoln, and has since moved to Mazda. He likes to golf, which I'm beginning to suspect is sort of a default answer for a lot of people, there are a lot of golfers around here. He's a Broncos fan, as he should be. No bias. He also told me about a very exciting trip to Mexico where he did the most daring thing he's ever done in his life, he bungee jumped! It hurt his back and he's never done it again. I have to say, I don't blame him. I've never hurt my back bungee jumping, but I have no interest in it, so now Adam and I have a lack of interest in bungee jumping in common, and I bet you may too. While in Mexico Adam was travelling through the countryside when he saw a cow on the side of the road trying to flag down passing cars. He pulled over because he's a kind and thoughtful person. It turns out the cow's friend was having a baby! But the first cow couldn't help, you know, no thumbs, and the inability to stand on hind legs, and it was a cow. So Adam jumped in! He delivered that baby cow with all the goop and nasty slimy stuff getting all over him and saved the calf. A true hero. I asked for one more fact about him and he told me that he's technically a native Coloradoan. I said, cool, what does that mean? He said, "well I was born in Colorado". I said, "I believe by definition that makes you a Coloradoan." He said, "Yeah, I guess so." The man can spin a tale, I'll tell you that.
- Rich Waters
- Mazda Finance Manager
- rwaters@sthmotors.com
Rich is a Harley riding nightmare of a man! But, like, in a loving way. Like, "Boy that Davy Crockett was a real Son of a Gun!" That's the kind of nightmare Rich is. He's been our Harley riding nightmare since 2020. He very much loves his motorcycle and says that his favorite place in the entire world is Sturgeous, South Dakota. When asked if he would retire there, he said no. He wants to retire to a bar on a beach somewhere, which apparently they don't have in South Dakota. Of course, if he goes the island route, it could be hard to ride the motorcycle. He also has a normal SUV. Because apparently on a day like today when the temperature is currently 11° and snowing lightly. (That's minus almost 12 for our Celsius folks). No matter what, it's too much for Rich to handle on his little motorcycle.

What can I say about Steve? Sometimes there is an employee who is so exemplary, so outstanding, so truly concerned about his customers, that words fail. And sometimes, that employee is also such a mystery that I literally can't come up with anything that I know about him to write a short bio. To that end, I know that Steve started at our Quick Lane in March, 2019, and was so good with customers, and adding numbers together, that he was promoted to the Mazda Service drive shortly there after. I can say that Steve's love of black clothing is apparent, and I suspect is impacted by his many years working in the dead of night as a member of an elite group of seals. Not the Navy group, just literally seals. Steve would dress up in his black wet suit and join his aquatic friends as they would swim through the night, keeping the bay free of sharks, and feasting on small fish. As we all know, night swimming is a young man's game, and so Steve joined us to care for our customers the way he cared for the swimmers in the bay who might be threatened by nasty sharks. Today all that remains of his past is his love of black clothes and the whiskers on his chin.
- Martin Richardson
- Mazda Service Advisor
Martin started selling cars here in 2017. His love of his Alabama heritage shows through, not only in his faint accent, but also in the Roll Tide bumper stickers on his car. Martin says he has a thick exterior, but really we all know he has a heart of gold and a great sense of humor. I think he's trying to lose weight as well, so that thick exterior isn't quite as thick. He doesn't need it in my eyes, but good for him. When he's not helping people get their cars into tiptop condition, Martin enjoys not working. He also enjoys golfing, which seems to explicitly counter the joy of not working, but I suppose he doesn't dig ditches on his off time, so golf is less work than that.
- Jordan Winner
- Mazda Service Department
- jwinter@sthmotors.com
Jordan re-joined our crew in late 2023 after taking an extended break to experience the most amazing thing any human can do. Skydiving. She also gave birth during that period, but big whoop, lots of people give birth. My wife gave birth. 3 times. You don't see her getting an award. Skydivers on the other hand, I bet they get a lot of awards, for like, falling the fastest, or... landing. She also told me that she likes to read. I didn't get much in the way of details on what she reads, but I'm sure reading helps her in many different facets of life, like driving. Being able to read STOP is very helpful. Or perhaps she reads classic tales of the great Samurai of Japan in their original language. I told you, she wasn't specific. Finally, she likes to hang out with her friends. I have got to start demanding more specifics, I literally wrote down "friends". What do they do? I don't know. She did say that Austin, our Volvo salesman, is her bestie, so I can pass that along! All in all, I think Jordan is pretty good at making friends. She's a bit quiet, and if you think she's looking down her nose at you, it's because her glasses have a tendency to slide down her nose and she's trying to keep them up. It's not personal.

Steve started in 2013 as our Mazda-parts guy, and sits in a small blue room with a window that is reminiscent of a drive-through. I keep hoping that he'll put on a turban and do an impression of Zoltan from the movie Big, I think he could pull it off in his little blue room. When he's not telling fortunes, Steve enjoys woodworking, building all sorts of great things out of wood like this table, these eating implements, or this chair.
- Homer Barraza
- Sales Guide
Homer - Homer has been with us for a while. I forgot to ask when he started, but it's been at LEAST a while. He did tell me that he plays 5 instruments! What are those 5 you ask? I don't know! Let's say, banjo, ukulele, guitar, bass guitar, and mandolin. Those seem like good options. He is a worship leader when he's not at work, leading the worship for the Brave Church. I typed this wrong initially and understood that he was a warship leader. That was a VERY different passion. He loves having a healthy / active lifestyle, there are lots of pull ups and carrots in Homer's world. When he's bored at the dealership he just starts running laps around the store. It kind of drives us all nuts, mostly because he can run so FAR without even sweating a little bit. Sometimes I drive next to him and pretend that I'm training him for a boxing match. We don't know each other terribly well, so I'm not sure if he understands what I'm doing. When he's not doing pullups or running, he's looking for somewhere to surf. Surfing is his life. In fact it's a huge reason he moved to Colorado when he was getting started in life. Everyone knows we have an amazing surf culture here, and he's frequently seen on Standley Lake catching some massive 6 - 10" waves when it's really, really windy out. Just between us, I have no idea how someone can believe that surfing is life and live in the semi-arid steppe that Colorado is. Finally, Homer would like you to know that he loves French Bulldogs. He loves their munched up little faces, their adorable buggy eyes, their bat like ears that stand on end and yet somehow don't help with nocturnal navigation whatsoever, and their absolutely priceless better than you attitude! Such cute little puppers.
- Jessica Ellerbrock
- Mazda Sales
- jellerbrock@sthmotors.com
Jessica joined us just before 2025 with a passion for Mazda unlike anyone else in our showroom. She's the only salesperson we have who has a Mazda tattoo, and draws Mazdas for fun, and drives a big, turbo, Mazdaspeed 3. That's right, it's big. Or the turbo is big and I put the comma in the wrong place. No matter which one it is, she's got one and loves it. She's got a border collie / husky mix pup that she named Mazda. She's a 6th generation Coloradoan, which actually predates Mazda as a brand, but her first word was Mazda. Of course it may have been mama, but she's pretty sure her mom just misheard her say Mazda. When Jessica isn't helping people find her, sorry, their favorite car, she loves to take photos of her favorite car. She has more pictures of Mazda on her phone than Mazda has on their website. I counted. She also has some beautiful pictures of other cars, but she's put black boxes over those cars, because, she says, they're not Mazdas, duh.
- Josh Ottmar
- Sales Guide
- Josh has been with Sill-TerHar since like 2019 or something. I forgot to ask. He's from Minnesota and enjoys crypto, hiking, & golfing. He has 2 cats. He plays video games. That's the boring stuff. He told me that he once played in the Metrodome. At first he didn't specify WHAT he played in the Metrodome, but he was very clear that the Metrodome is a stadium in Minneapolis. It's where the Minnesota Vikings used to play football, but now they play in U.S. Bank Stadium which is way fancier and has one of those much cooler corporate names that never seem to make sense. Josh has never played anything there. But I did find out that he played the flute in the Metrodome. All by himself. It was empty one night and he snuck in and had a grand ol' time running around the field with his little flute.The most exciting moment of his life seems to be the time he caught a muskee. He told me that with such excitement that I assume a muskee must be a very rare Pokemon or something. Apparently not many people catch a muskee. I thought I had heard of it, but then I realized I was thinking of the Tuskegee Airmen. They just sound the same, but they're not. If you're familiar with muskee, then you should reach out to Josh and let him know how proud of him you are.

- gsimcakoski@sthmotors.com
You know sometimes I look at the notes I took for people and I wonder what the heck I was thinking. Gerik's notes say Skiing. Cooking. Italian. Spy. I remember a lot of our conversation, but I'm sure he's not Italian, he said that he was of Russian descent at least 4 times... Which made me think he was probably a spy, otherwise why would he keep pointing it out! That makes way more sense now, although you'd think it would be easier to just write "Russian". And, now I'm pretty confident that Gerik likes to cook Italian food. I vaguely remember him talking about taking classes on how to cook like a true Italian from some New Yorker on YouTube. He said that they didn't teach him anything about food, just how to yell at people who are in the kitchen while gesticulating wildly. (That means waving your hands around) As for the skiing thing, I'm guessing that he just likes to ski. I like to ski also, but this isn't about me is it. I don't get a bio, because I hide in the back office with my head down slowly growing bitter and... Nevermind. Let's talk about the fact that Gerik loves to ski all kinds of terrain, and really loves riding all kinds of lifts. He said that the kind without a lap bar are his favorite because it feels like he's flying like a squirrel.
- Abraham Woods
- Ford Sales
- awoods@sthmotors.com
Abraham likes to be called Abraham. Or Abe. Or Abram. Or, oddly, Cuddlesnuggles. He joined us in late 2024 and came from Indianapolis. Everyone knows that you can't come from Indianapolis and not be a fan of golf. They have that really cool course that someone built a racetrack in the middle of. Cuddlesnuggles isn't a big fan of golf apparently, he's more a fan of the car racing that happens around the golf course. He loves watching Indy car racing, and driving fast cars when he's allowed to. He has a pet cat. He didn't tell me anything about the cat. So that's all you get. He has a pet cat. He went to private school, presumably in Indianapolis and then decided to join the US Marine Corps. As a Marine he did what any true Marine strives to accomplish, he became a mechanic. No one shot at him at all while he was in the Marine corps, but their trucks ran like butter.
