Neighborhood spotlight
Wild Horse Ranch
Just west of Laramie, Wild Horse Ranch sits at the foot of Sheep Mountain, where timbered slopes give way to rolling grassland, big-sky views, and 35–45 acre parcels. Lake Hattie and Twin Buttes are minutes away, the Snowy Range and Medicine Bow National Forest fill the horizon, and antelope, deer, elk — and the ranch's namesake horses — wander through daily.
Mariah works Wild Horse Ranch constantly — vacant land, custom homes, lakefront tracts, and everything in between. If you're curious what your parcel is worth or want first word when something hits the market, few agents know this subdivision better.

“Dr. Mariah Jeffery is without a doubt, the highest caliber Realtor in southeast Wyoming. Across the world during military tour, I cold called her to take action on a house that I thought would be gone incredibly quick. She was out at the house with videos within an hour. … I will forever be grateful for her efforts in making our forever dream home happen at the drop of a hat.”
“I had the pleasure of working with Mariah to sell my home in Cheyenne, WY, and she made the entire process effortless and rewarding. Right from the start, her expertise in the local Wyoming market was evident — she offered smart insights on pricing, marketing, and minor updates that positioned my property perfectly for buyers. … Thanks to her sharp negotiation tactics, we secured a fantastic deal well above our expectations.”
“She handled several complex investment property transactions for me with exceptional skill and grace. Though I was not in Wyoming at the time, Mariah's commitment and attention to detail ensured that distance was never an issue. … What truly sets Mariah apart is not just her expertise, but the way she operates — with honesty, class, and genuine care.”
