Employee Recognition
At Alta Mira, we know that client interactions with staff highly influence the results of our program. From the moment you arrive at Alta Mira, our team works to make sure you feel welcome, safe, respected, and comfortable. Because we understand just how important our staff is to the client’s experience at Alta Mira, we are highly selective in choosing team members. Each staff member is chosen based on their ability to provide clients with the most advanced care possible, while ensuring clients feel secure and understood. Many members of our staff are also in long-term recovery and have first-hand experience as clients in treatment. The perspectives of staff who have “been there” are highly valued, because they help increase understanding and empathy across our whole team. Alta Mira’s Luminary Excellence Award Program (LEAP) gives Alta Mira the opportunity to recognize the difference our employees make every day to fulfill our mission of bringing hope and recovery to the people we serve.
