Making History
The late Carl Mosen and Kevin Mello, co-founders of Hotel California by the Sea, shared a powerful vision: to create a treatment center that offered compassionate, individualized care for people struggling with drug and alcohol addiction.

Carl, who was proudly over 40 years sober when he passed away, dedicated his life to helping others find the same freedom he had discovered. He was immensely proud of his sobriety, and it became his mission to save as many people as possible from the pain of addiction. His own journey gave him deep empathy, a sharp sense of purpose, and a passion for creating lasting change.
In 2014, Carl partnered with Kevin Mello to bring that vision to life. Like Carl, Kevin is also in long-term recovery and understands the transformative power of treatment. Kevin’s own experience with addiction and recovery inspired him to build a healing environment where clients could feel safe, supported, and understood from the moment they walked through the doors.
Together, Carl and Kevin built Hotel California by the Sea on the foundation of empathy, expertise, and excellence. Their goal was to address the full spectrum of addiction and co-occurring mental health conditions while maintaining a culture rooted in dignity and individualized care.
From the beginning, Carl’s influence shaped the culture and heart of HCBTS. He believed that recovery was not just about abstinence—it was about healing every part of a person’s life. He made it clear: every client’s story mattered, and every recovery journey deserved attention, respect, and hope.
Because of Carl and Kevin’s leadership, Hotel California by the Sea quickly became one of the first comprehensive residential treatment programs in Newport Beach, CA. Their partnership set the standard for what compassionate, clinically-sound recovery could and should look like.
“We Need Something Different” – New Frontiers In Addiction Treatment
Carl and Kevin understood that recovery is not one-size-fits-all. They worked to develop programming that was as unique as the people they served—offering a wide range of services, from medical detox to outpatient treatment and long-term continuing care. Their focus was always on treating the whole person: mind, body, and spirit.
Carl’s legacy lives on in every aspect of the program he helped create. His commitment to personalized care, client dignity, and high standards continues to inspire the team at Hotel California by the Sea today.
Thanks to the groundwork laid by Carl and Kevin, Hotel California by the Sea has helped thousands of individuals and families find lasting recovery, and that mission only continues to grow.
Crossing State Lines
Our flagship location is set in Orange County, California. However, within the past few years, Hotel California by the Sea has grown professionally and as a family. This has allowed us to treat thousands of patients nationwide and expand our helping reach beyond California’s borders.
Bellevue, Washington
After realizing a significant amount of our clients came from the Seattle area and other parts of the Pacific Northwest, our Vice President, Brian Burke, decided to bring Hotel California by the Sea to his home area in the Pacific Northwest. It was evident that there was a growing need in the Pacific Northwest for trustworthy long-term treatment for addiction.
In 2015, Hotel California by the Sea Bellevue was born. It opened its doors to provide outpatient treatment services and private recovery residences for people looking to recover from drug and alcohol addiction and any co-occurring mental health conditions. In 2018, we opened our residential detox in a beautiful home in Kirkland, WA. We have plans to continue expanding our resources in the Seattle area.
Cincinnati, Ohio
Hotel California by the Sea opened its doors in Cincinnati in 2018 and continues to serve the Midwest and North East regions. Nestled in the heart of the Queen City, our rehab center offers a tranquil and supportive environment for individuals seeking trying to overcome addiction.
We have always believed in making excellent addiction treatment accessible. We are honored to provide the Greater Cincinnati area with all levels of care. We are dedicated to providing a safe and nurturing haven where individuals can start their recovery journey and build their foundation for a brighter future.
Our dedicated staff worked tirelessly to support clients on their sobriety, offering a range of evidence-based treatment programs tailored to meet each individual’s unique needs.
