Owners
Raul Castellanos Jr., CFO & Kristina Patrick, CEO
Our owners, Raul and Kristina, bring a hands-on, service-driven approach to property management, built on years of experience and a deep connection to the Mammoth Lakes community. Raul’s family has been part of the area since the early 1980s, and he has been visiting and working in Mammoth since his father first moved there. Raul and Kristina made Mammoth Lakes their home in 2015, and in 2017 they bootstrapped Mammoth Landscape from the ground up, building its reputation reliability, transparency, and high-quality workmanship. Their landscaping business grew, clients began relying on them for more than just landscaping, asking for help with a wide range of property needs. Seeing that demand, Raul and Kristina expanded into property management. They worked within Mammoth Homeowner’s Services for a year to fully understand the industry and refine our systems before deciding to purchase the company.
Today, with both companies thriving, they have continued to grow to meet the needs of their clients and HOA communities by expanding into construction services via Mammoth Construction, Inc. As licensed contractors, they now provide a true full-service solution covering property management, landscaping, snow removal, and construction all under one roof. Their commitment remains the same from day one: reliable service, strong communication, and getting the job done right.
