Matt Ehler
Chief Executive Officer

Matt is the CEO at Prosperity Wellness Center and has been working in the behavioral health system for 17 years in a variety of settings, particularly in improving and expanding service delivery. Across several states in the western U.S., Matt’s experience has ranged from leading community-based treatment teams to involuntary acute inpatient to a state reviewer of mental health agencies. Opportunities to learn new skills, problem solve and find new ways forward keeps Matt energized.  A joy for problem solving, along with collaboration and seeking common ground, are the skills Matt likes to bring to any situation. Matt states: “I believe every individual in the work environment is a key piece to the puzzle and to the success of reaching any goal. To that end, I seek to cultivate an environment in which everyone is treated with kindness and respect, encouraging the authentic expression of everyone. My favorite quote is from Oscar Wilde, who encourages us by sharing: ‘Be yourself; everyone else is already taken.’”

Jill then became an alum and started working at Prosperity in 2018. When Jill started, she was working at the front desk as an administrative assistant. Jill is currently the admissions manager and loves what she does. “I have a strong desire to help people who struggle with substance abuse by listening to them and assisting them with the tools to get started on their journey of sobriety,” says Jill. She has three adult children and two grandchildren, whom she absolutely adores.

Danita Davis
Kitchen Manager

Danita is the manager of the kitchen at Prosperity Wellness Center and has worked here since 2022.  Danita originally hails from Philadelphia, Pennsylvania. She has called the West Coast her home for about 10 years. Danita was attracted to the West Coast because she has family here and loves the amazing climate.  Danita has been in the cooking industry for over 30 years. Her love of cooking started at the Philadelphia International Airport Marriott, where she worked for 18 years. During that time, Danita learned a great deal about the importance of eating first with your eyes, then with your palette.  Danita had “15 minutes of fame” while working at the Philadelphia Marriott, with her cornbread being a favorite of the NFL Philadelphia Eagles players as well as some celebrities. Danita has also worked at hotels and a nursing home in the food prep industry, as well as for banquets doing hot prep, omelet stations and carving stations.  Although she did not go to culinary school, she considers her employment within the food industry to be her professors. In turn, Danita is passionate about sharing her knowledge with others, in hopes to jump-start their own food industry experiences. Danita believes that cooking is trial and error, but if it comes out good, it makes the experience worth it.

Danita had not worked with the homeless shelter until she came to Washington State. Danita, who experienced homelessness at a time, says working at a shelter gave her a more compassionate perspective. “[Working at a homeless shelter] gave me the opportunity to treat every man, woman and child as though they are VIPs,” says Danita. “This is how I would have wanted to be treated if I lived in a shelter environment.”  Danita adds: “We should not judge people for what they have; we are all God’s children and there are many components that makes us who we are. Things are just things [and] we are more complex than that. This collection of words is, in my opinion, perfectly constructed and I live by its meaning: ‘Everyone deserves a chance at recovery no matter where you have been.’”  Danita has a passion for showing others that the evidence of God’s love comes in different ways, and cooking and listening to others is how she shows her love. Outside of Prosperity, Danita enjoys being with her many friends and family. To conclude, Danita declares, “I’m blessed.”
