Making History

In 1986, Carl Mosen, later founder of Hotel California by the Sea, saw the need for a safe, structured, and sober environment for people recovering from drug and alcohol addiction in Southern California. So, Carl decided to start Sober Living by the Sea, a halfway home close to the ocean where homeless men could live (for free) and get their lives in order. These men were required to lead a sober lifestyle and were encouraged to take the necessary actions to mend what was broken in themselves and their lives. Needless to say, Sober Living by the Sea touched the lives of a countless variety of individuals.

Carl, who now has over 30 years of sobriety, owned and operated Sober Living by the Sea from 1986 until 2006. Afterward, however, Carl still felt an immense calling to continue his work in the recovery industry. So, sharing a deep passion for helping those struggling with addiction, Carl and his business partner, Kevin Mello, started Hotel California by the Sea in 2014. They each shared a vision for Hotel California by the Sea to be an innovative and healing environment close to the ocean for people who wanted to get clean. Soon, their vision was realized.

Similar to Carl, Carl’s business partner and co-owner of HCBTS, Kevin Mello, struggled with addiction. Kevin witnessed the powerful connection between long-term treatment and his very own long-term sobriety and recovery while getting sober. Knowing the correlation between long-term treatment and successful recovery is just one of the experiences that inspired Kevin to build Hotel California by the Sea’s thriving community of passionate addiction experts. 

Carl Mosen brought over 30 years of personal experience and professional success into the field of substance abuse treatment when he founded Hotel California by the Sea with Kevin Mello. HCBTS became one of the first, if not the early, residential treatment programs for substance use disorders in Newport Beach, CA. 

Without a doubt: Hotel California by the Sea set the unparalleled precedent for Orange County’s now-thriving addiction treatment network.

“We Need Something Different” – New Frontiers In Addiction Treatment

Carl carried and applied his decades’ worth of experience of working in hyper-focused and specialized treatment programs to the creation and development of Hotel California by the Sea. While still in its infancy, Carl knew that he wanted HCBTS to be a special place that addresses each client’s personal story. 

Everyone’s story is different, and Carl knew well that his job, and the job of others who would eventually work with him, was to hold these stories with care. Through seeing clients for who they are (and not just their disease of addiction) and applying the necessary and specialized therapeutic models of treatment, Carl knew that clients could recover fully from substance use disorders. 

Because Carl installed a culture of individual-focused treatment into his staff and his company, he encouraged creating different treatment programs at HCBTS.

Individuals in each of these age groups have the opportunity to address issues that accompany their addiction, such as co-occurring mental health conditions, trauma, and more. Today, thousands of recovered addicts and alcoholics call Newport Beach home because of Carl’s local leadership and involvement in the recovery community. Carl has sustained this legacy by consistently offering high-quality and specialized addiction treatment to men, women and young adults suffering from substance use disorders at Hotel California by the Sea.

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.
