At Naples Regenerative Institute, double board-certified pain management specialist and leading regenerative orthopedic medicine physician Glenn Flanagan, MD, offers comprehensive treatments and cutting-edge care in Naples, Florida. ​

If you’re looking for a caring and thoughtful physician who spends time listening to each patient at every visit to organize a customized and individualized plan, look no further. Whether you have neck pain, back pain, or painful joints, rest assured, the team is here to help.

In July 2019, Dr. Flanagan opened Naples Regenerative Institute, pledging to offer his patients an integrative blend of traditional pain management treatments and state-of-the-art orthobiologic injections such as platelet-rich plasma (PRP) and stem cell treatments. He trained with worldwide leaders in his field and is one of few physicians in the world trained and certified to provide regenerative treatments for the entire scope of orthopedics.

Dr. Flanagan was born and raised in Long Island, New York, and went to Emory University in Atlanta, Georgia, for college. He met his wife, Phuong, at St. George's Medical School on the sunny beaches of Grenada. He then completed his residency in anesthesiology and a fellowship in non-surgical spine and joint treatments at Syracuse University in Upstate New York, while his wife completed her residency in internal medicine at the University of Southern California in Los Angeles, California. Shortly after completing all of their training, they moved to Naples, Florida, to begin practicing as physicians.

Over the years, Dr. Flanagan has learned a lot about nutrition and exercise in an effort to help patients. These have become hobbies and are a huge part of patient education in his practice. A thorough evaluation of your spine and joint problems allows Dr. Flanagan to improve outcomes by coordinating care for his patients from head to toe.

Aside from medicine, Dr. Flanagan has always loved playing sports. In his spare time, he still plays some golf, basketball, and softball.

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. Upon completing his residency, he began his pain management fellowship training at the University of Pittsburgh 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. With the use of intrathecal drug delivery, Dr. Jung was able to get patients off oral opioids while continuing to treat patients who required opioids in a safe, controlled manner that was physician-controlled.

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.
