David Abram
My days in the gym began as a toddler sitting in the fitness center nursery. My mother exercised daily and played tennis. She ensured I was always a participant in athletics throughout my schooling. My first job was in a local gym where I learned how to transform not only the physique, but the mind and spirit as well. Through focus on the mind-body connection, I was able to augment my physical shape, using the gym and it’s required focus as a coping skill that helped reprogram my attitude and brain. The gym is a place I find solace, a place I can return to whenever I need to reset.

Early on I found my addictive behaviors show up in the way that I ate food. Later in life it was found in the way I used substances. Those behaviors altered my life path, hindering my success and ultimately costing me enough to need recovery. What I have found from my past experiences, as well as my new ones, is that recovery is a comprehensive mission. A mission that is best accomplished using exercise, nutrition, and many other recovery-based tools to be successful. My goals grow and change continuously, but my daily habits help me flourish in life.

Using exercise and healthy eating habits as a cornerstone for change, I show up with enthusiasm hoping to inspire others to see the same on their journey in health and wellness. Being a part of solutions in recovery wellness center has been a gift, and I feel privileged to lead others in this health and wellness program through CCI.

Emily Skillings

My Love for physical fitness was established at an early age. Dancing, hiking, biking, rollerblading, and snowboarding were many of the activities I enjoyed growing up. I am originally from Salt Lake City, Utah and have been residing in San Diego since January of 2016. Since moving to California, I have furthered my passion for physical activity, utilizing physical fitness to help individuals suffering with mental illness and substance abuse. This is something I identify with due to my own battle with addiction and depression. I personally use physical fitness and proper nutrition as staples in my recovery journey.

Fitness to me, is not just about physical appearance, fitness is a lifestyle choice that requires practice. That practice should continuously evolve in knowledge and experience, just as we do in life. I honestly believe that fitness can support a person healing their mind, body, and soul. Being a part of the Solutions Wellness Center has changed my life in many positive ways. My hope is the Wellness Center will do the same for the clientele we serve. Supporting them in finding healthy habits and a renewed sense of self-love and self-confidence.

I have obtained several training certifications including Inferno Hot Pilates, Above Barre, TRU breathwork and Beyond addiction yoga.

Jeffrey Klein
Executive Director, CCI

After 11 years of experience in the field of Information Technology, Jeff was inspired to change careers as a result of his own experience with treatment and recovery in 2005. While completing his education in alcohol and other drug studies (AODS) at San Diego City College, he was hired at a long-term, residential treatment center for those suffering from severe psychiatric disorders and drug addiction. During his six year tenure, Jeff gained extensive experience in crisis intervention, case management and the overall treatment of co-occurring disorders. As Milieu Operations Director, he was instrumental in the development of the Chemical Dependency Department and was responsible for oversight of the company’s support staff and Housing and Admissions Departments.

In an effort to make treatment more accessible to those suffering from acute psychiatric symptoms, Jeff extracted tools and techniques being practiced in long-term psychiatric care and coupled them with his knowledge of standard chemical dependency interventions. This new and effective modality has since been adopted by the Intervention and Recovery Institute (IRI) in San Diego and continues to yield highly successful outcomes.

In 2013, Jeff was instrumental in reopening Pemarro Recovery Center, a sub-acute medical detoxification facility. While there, he worked diligently to build a comprehensive treatment program, focusing on providing clients a safe and effective detox and creating individualized transition plans to provide a structured path for clients to follow once they discharge.
