Growing up, Dr. Rubin always had an affinity for the science of cardiac structure

                                                                            and function which triggered his analytical style of studying the heart. “The field 

                                                                            of cardiology lends itself to the investigation of the heart’s electrical, mechanical and biological properties, which I find fascinating,” he said. “Cardiology allows me to explore and treat diseases of the heart from a much wider vantage point than can be performed in other subspecialties.” According to Dr. Rubin, artery and valve stents have revolutionized the treatment of coronary artery disease and valve disease. “This has significantly reduced need for invasive surgery,” he added.

​Dr. Rubin has a special interest in congenital heart disease in adults. When he was five years old, he found out that his heart was on the right side of his body instead of on the left when his family physician made the diagnosis. “It wasn’t until I got to medical school that I found out all

my organs were mirror image reversed. Although this is very rare, it has not caused me any disability, and in fact, has piqued my interest in cardiology and its various maladies. It has also given me perspective to understand that which does not always fit into common knowledge of the facts, doesn’t mean it’s untrue.”

Philosophy of Care
Dr. Rubin believes in taking an “old fashioned approach” when caring for his patients and their families. “I want my patients to communicate freely with me so that I can provide the greatest level of care to them, as well as their family members,” he said. “I also work hard to get to know my patients which helps me accurately diagnose their condition and treat their needs optimally. This includes ensuring that they have the opportunity to be fully heard and acknowledged as individuals.”

Dr. Rubin and his wife Liza have two adult children. Their son, Matthew, is an EMT and will be soon starting medical school and their daughter, Danica, works in financial project management. In his spare time, he likes travelling both across the U.S. and around the world. Dr. Rubin enjoys living and practicing in the USVI because of the warmth and generosity of the Crucian people.

About US

Urgent Care is the delivery of medical services outside of the hospital emergency department and is generally administered on a walk-in or unscheduled basis. Ever gotten a small cut on your finger while cooking? Treat it at home. Are you or a loved one having signs or symptoms of a heart attack? Go to the ER. Everything in between is Urgent care. Our Urgent Care center treats patients who are in need of immediate medical attention and choose to bypass a visit to the emergency room because of cost or ailments that are not serious enough to require hospital emergency services. Urgent care is not meant to substitute a necessary visit to the ER or primary care physician, but we provide an alternative to these with the ability to provide excellent treatment for most illnesses and injuries.

In 2000, answering a deep-rooted call to return to the Caribbean where he spent his formative years, Dr. Campbell accepted an opportunity to become the assistant director of the Department of Emergency Medicine at Gov. Juan Luis Hospital on St. Croix, U.S. Virgin Islands. Dr. Campbell eventually became the director of the department, and later helped develop and oversee the hospital's Fast Track program. He was also named the first director of the hospital's Ambulatory Care Services.

Driven by his strong Christian faith and beliefs on helping people in his community, in 2006 Dr. Campbell founded Acute Alternative Medical Group, a private medical practice where he currently serves as medical director. In 2009, Dr. Campbell expanded Acute's services when he opened St. Croix's only accredited sleep disorder treatment practice, Acute Alternative Sleep Center. And utilizing his knowledge and expertise in emergency medicine, Dr. Campbell expanded the medical practice by opening St. Croix's first urgent care center, offering a more convenient and accessible alternative to the nearby hospital emergency room.

In addition to Acute being a traditional medical practice, Dr. Campbell, with a strong desire to have a positive impact on his patients' health and wellbeing, also decided to offer scientifically researched alternative medical tests and therapies to his patients. He also medical-grade supplements and a nutrition bar that offers nutritious smoothies and snacks.

Throughout his medical career, Dr. Campbell has dedicated is life and career to improving the health of his patients. But more importantly, his faith and values have been cornerstone of his commitment to bettering the lives of his family, his patients, and his community.
