Dr. Justin J. Clark, MD, FACS, Surgeon
Dr. Justin Clark was born and raised in San Diego, California. He grew up as an avid tennis player and enjoyed golf, hiking, fishing, and camping. In college he played tennis and rowed crew at Oxford University in England. He has traveled extensively throughout North America, South America, Europe, Africa and Asia. Dr. Clark now lives in Anchorage and has two beautiful daughters.
Dr. Clark chose to become a surgeon because he finds the operating room to be a sanctuary of sorts. When in the operating room time seems to stop and all the chaos of the outside world fades away. He feels focused, fully immersed, and experiences extreme gratification.
“It is a wonderful feeling to be able to help someone who has chosen to take control of their weight and is motivated to change their life. Every single time I have a patient return after surgery and thank me for giving them their life back, I get to renew my love of bariatric surgery.”
Dr. Clark served with distinction in the United States Air Force. Commissioned as an officer in 2002, he then entered medical training before going Active Duty in 2012. He served as a Major at Joint Base Elmendorf Richardson Hospital until 2016, where he was director of bariatric surgery and assistant director of trauma surgery. He participated in missions all over the Pacific theater, including traveling with President Obama to Malaysia as surgical support staff.
Dr. Clark stayed in San Diego for his undergraduate education at the University of California at San Diego where he obtained a B.A. degree in history. He spent his junior year abroad studying at New College, Oxford University in England. After graduating, he spent a year traveling and enjoying time in Europe and Africa. He entered medical school in Chicago at Northwestern University in 2002, and graduated with a medical degree in 2006. He then performed a general surgery residency at the University of Hawaii in Honolulu for five years. He was very fortunate to secure one of the nation’s top fellowship positions at Duke University and spent the next year in intensive training in bariatric and minimally invasive surgery. Upon finishing his fellowship, he entered active duty with the USAF in July 2012. He became Board Certified by the American Board of Surgery in 2014, and was inducted into the American College of Surgeons in 2015. He is also a participating member of the American Society of Metabolic and Bariatric Surgery.
Dr. Clark currently serves as Director of Metabolic and Bariatric Surgery at Providence Alaska Medical Center.
FACS: The FACS designation (Fellow, American College of Surgeons) after a surgeon’s name means that the surgeon’s education and training, professional qualifications, surgical competence, and ethical conduct have undergone a rigorous evaluation and have been found to be consistent with the high standards established and demanded by the College.
“Dr. Clark was great, he never chastised me for being overweight. He was very open and supportive and checked in with me every day after my surgery.” – Russell F.
“Dr. Clark is always positive, uplifting, and encouraging. He’s that go-to person you want by your side to guide you. He’s not pushy, just informed and knowledgeable, and you can trust him right from the start. I was scared, but his confidence made me comfortable.” – Maddie P.
Dr. Sean M. Lee, MD, FACS, Surgeon
Dr. Sean Lee was born and raised in the suburbs of Seattle, Washington. Growing up, he was active in various sports including basketball, golf, tennis, and snow skiing. Dr. Lee attended Cornell University for his undergraduate studies, then went on to the Yale University School of Medicine in New Haven, Connecticut where he received his Medical Doctorate. He spent a fifth year at Yale performing research in bone marrow-derived stem cells, with the support of a grant from the Howard Hughes Medical Institute.
Dr. Lee completed his residency in general surgery at Duke University in North Carolina. While there, Dr. Lee decided to focus his clinical work toward bariatric surgery. He was drawn to bariatrics due to its proactive nature. Rather than responding to a severe disease or injury after it occurs as in most surgical specialties, bariatric surgery addresses obesity early in its course and can prevent, improve, or even resolve multiple other diseases related to obesity. Being able to partner with patients to affect a dramatic positive change in their health, and seeing how their lives change for the better was extremely rewarding.
In his final year of residency, Dr. Lee met Dr. Justin Clark when Dr. Clark started his fellowship in Bariatric and Minimally Invasive Surgery at Duke. The following year, as Dr. Clark moved on to Anchorage, Dr. Lee began his specialty training in the same program at Duke.
In 2016, Dr. Lee became the head of the Center for Obesity and Metabolism at Augusta University, and facilitated the bariatric surgery program’s recognition as an MBSAQIP bariatric surgery Center of Excellence. Dr. Lee was inducted into the American College of Surgeons in 2018.
Dr. Lee has learned that obesity is not a cosmetic problem suffered by those lacking self-control. It is, rather, an increasingly common, potentially lethal disease affecting millions of Americans of all backgrounds, including some of the most disciplined and hard-working people he has known. It is an epidemic with an insidious nature, and one that requires we apply those treatments proven to be safe and effective.
In 2017, Dr. Lee moved to Anchorage to join Dr. Clark as a partner-owner of Anchorage Bariatrics. His current goal is to work with the team at Anchorage Bariatrics to bring the highest quality bariatric and minimally invasive surgical care to the people of Alaska.
“I was very nervous and a little bit emotional, but my first visit with Dr. Lee was amazing. He was very informative. Every time I have seen a doctor for weight issues, I always felt like I was in trouble or was being judged. This time, I didn’t feel that at all. It was finally my choice to get help and everyone at Anchorage Bariatrics made me feel comfortable.” – Cara H.
“When we made our initial appointment to see Dr. Lee, we just absolutely fell in love with him and the staff.” – Tim C.
“Dr. Lee is fantastic! I like his personality and I like the way he breaks things down for you. He is very detailed, so there was no point in the process where I didn’t understand things. He is very comforting to talk to and very welcoming.” – Jennifer D.
