Certified by the American Board of Addiction Medicine and the American Board of Emergency Medicine, Daniel Smeester, MD, is a drug and alcohol addiction treatment specialist in California’s San Francisco East Bay. His state-of-the-art Inpatient Medical Detox program allows people to safely stop their use of alcohol and other substances, even fentanyl, in the comfort of our luxury inpatient program. We still have our complete outpatient program. All treatment is confidential, comfortable, and successful with an MD always! This, combined with our residential program lasting as long as 30 days, followed by intensive counseling (IOP and PHP), leads to significant success in the treatment of addiction.

He helps run a practice specializing in Addiction-free Pain Management with interventional pain management services in the same office. Offered are much safer and more effective medication management options for chronic pain than the typical prescribed opiates. With more than 20 years of experience, Dr. Smeester is the Clinical and Medical Director of Diablo Valley Drug and Alcohol Services in San Ramon, aka Diablo Valley Treatment Center, and the Center for Pain and Rehabilitation (CPR).

Dr. Smeester graduated from Ponce School of Medicine, a U.S. medical school in beautiful Puerto Rico.

Passionate about addiction treatment, Dr. Smeester was board-certified as an addiction medicine physician in 2014. He has since dedicated his life to fighting drug and alcohol dependence and addiction at Diablo Valley Drug and Alcohol Services, which has earned its Commission on Accreditation of Rehabilitation Facilities (CARF) accreditation since 2016.

Dr. Smeester has seen how inpatient treatment may be unobtainable due to disruptions. Thus, we developed a treatment program in a luxurious setting, so the investment of time and finances will be well worth it.

As a compassionate addiction specialist, Dr. Smeester understands that those struggling with addiction and substance abuse aren’t always treated with the dignity they deserve. That’s why he’s carefully built an environment where his patients can feel comfortable, respected, and valued. Magnolia Recovery is an inpatient facility in a luxury setting specializing in medical detox and residential care.

Promoting health and recovery, he and his team offer a number of outpatient services and evidence-based treatments, including medication-assisted treatment (MAT), group therapy (IOP and PHP), family counseling, individual counseling, detox services ( the only certified and accredited outpatient detox center in or near the San Francisco Bay area), and more.

Soon Jung, MD, is a pain management physician at SEPA Pain & Spine in Horsham, Langhorne, Chalfont, and Meadowbrook, Pennsylvania. He joined the team in 2021.

Dr. Jung is originally from the New York metro area. He graduated from the State University of New York Binghamton University before completing his medical education at SUNY Upstate Medical University in Syracuse, New York, in 2010.

He began his medical career as a neurosurgical resident at Rutgers New Jersey Medical School in Newark, New Jersey. After completing multiple years of training, Dr. Jung realized that, unfortunately, many patients continued to have chronic pain despite surgery, and during his time there, he became exposed to chronic pain management under the tutelage of Dr. Andrew Kaufman.  

After seeing the positive and life-changing impact of helping someone alleviate chronic pain, he decided to pursue a career in pain management. Therefore, he made a career move and began his anesthesia training at the Westchester Medical Center.

After completing his fellowship in 2016, he became an attending physician at the Lehigh Valley Medical Center in Allentown, Pennsylvania. While there, he was in charge of the neuromodulation program and the intrathecal pump program.

He is double board-certified in anesthesia and pain management. Because of his neurosurgical background, he brings a unique skill set not found in most pain management physicians to SEPA Pain & Spine.  He believes that every patient’s pain is unique and that treatment plans should be catered to the patient’s needs. He brings with him experience and knowledge in all areas of pain management, including medication management as well as minimally invasive procedures designed to treat chronic pain.

Dr. Jung now resides in the Blue Bell area and is married with three young children. He spends his free time combing the country for the newest and latest ways he can treat his patients. He feels blessed that he can truly say that for him, his work is his hobby.
