Business Development Director
Hi! I’m Tatum, Business Development Director for Grand Welcome Mammoth Lakes. With a background in education and leadership, my career has always been centered around building strong relationships and delivering meaningful results. Having stayed in hundreds of short-term rentals across the U.S., Europe, and Africa, I bring a guest-first perspective that helps properties stand out. I use that insight to help homeowners increase bookings, improve guest experience, and maximize their return with a strategy that actually performs.
With two littles, Mammoth Lakes has been such a fun place for our family year round. In the winter we love getting out in the snow and just enjoying the mountains, and once it warms up, we’re always out exploring the trails.

Stuart Macheske
General Manager
Hi, I’m Stuart Macheske, and I’m proud to lead the Grand Welcome team in Mammoth Lakes. I’ve worked in real estate since 2015, with experience in brokerage, development, and property management. I started my career as a broker in Detroit, MI, and later managed both long-term and short-term rentals. That well-rounded background gives me a strong understanding of what it takes to protect investments and grow revenue. My passion lies in creating great experiences for both homeowners and guests through clear communication, high standards, and a hands-on approach. At Grand Welcome, I focus on optimizing bookings, keeping properties well-maintained, and ensuring smooth guest stays. Every detail matters, and I’m committed to making sure each home is managed with care and professionalism.
I absolutely love Mammoth, CA, for its stunning alpine scenery and year-round outdoor adventures. Whether I'm skiing at Mammoth Mountain in winter or hiking the Lakes Basin Trail in summer, I spend as much time as possible outside.

Mammoth is a place that never stops inspiring me, no matter the season. In the warmer months, I love hiking the scenic trails, paddleboarding on the lakes, and unwinding in nature. There’s nothing better than ending the day with a sunset over the mountains and the fresh alpine air all around.
