The people behind the practice.

Dr. Bharath Thankavel brings more than two decades of experience spanning clinical medicine, payer strategy, and health system leadership. He began his career as a Pediatric Hospitalist at UT Southwestern Medical Center, where he served as Assistant Professor and sat on the Medical Executive Committee.

Dr. Thankavel went on to build Children’s Health’s Home Care department, scaling it to serve over 1,500 patients before joining Blue Cross Blue Shield of Texas as Medical Director of Value-Based Care, where he partnered with 31 ACOs covering 1.8 million members statewide. Most recently, he served as Vice President of Network Integration & Cardiovascular Services at HCA/Medical City Healthcare, overseeing 16 cardiac programs in North Texas.

He served as a Texas Gubernatorial appointee to the Statewide Healthcare Coordinating Council, a Board Member of the North Texas Commission, and is an alumnus of Leadership Dallas.

His expertise is in advancing clinical quality, aligning strategy, deepening partnerships, and supporting the teams who deliver care every day. His career reflects a sustained effort to understand healthcare from multiple vantage points and to use that perspective to build organizations that perform.

Dr. Christine Crocker is a board certified internal medicine physician providing concierge primary care for adults 18 and over at Marquis MD in Boca Raton. Her expertise runs from prevention to complex chronic disease, incorporating weight loss, hormone replacement therapy, functional medicine, and longevity medicine.

She earned her medical degree at the Lake Erie College of Osteopathic Medicine and completed her internal medicine residency at the University of Pittsburgh Medical Center, where the American College of Osteopathic Internists honored her with its resident award for humanism and teaching. She also holds a Juris Doctor, and it shows in how carefully she listens, reasons, and advocates.

Dr. Crocker began her career in her native western Pennsylvania, caring for a community with a heavy burden of illness and becoming expert in complex disease. As the quarterback of each member’s care team, she coordinates every specialist, reviews every note, and advocates for the person in her care at every step.

Her philosophy is simple: meet each member where they are. She treats the whole person, physical, emotional, and psychological, with straight talk, an open mind, and an unhurried conversation. Marquis MD gives her the platform to practice medicine the way she has always dreamed of.

Dr. Douglas Barlow is a board certified pediatrician who brings more than three decades of experience to the children and families of Marquis MD in Boca Raton. He has devoted his entire career to young people, from their first days through the college years.

He earned his medical degree at New York University School of Medicine and completed his residency at Long Island Jewish Medical Center. Much of his career has unfolded in Boca Raton, where he founded his own practice, served as Chief of Pediatrics at Boca Raton Community Hospital, and was team pediatrician for the Florida Panthers. He has held associate professor appointments in pediatrics and is fluent in Spanish.

His commitment reaches beyond the exam room. He led pediatric care at a field hospital in Baton Rouge after Hurricane Katrina and served three tours as chief pediatrician in Haiti following the 2010 earthquake.

Ask Dr. Barlow what sets his care apart and the answer is time. He sits down, listens without hurry, and treats parents as the true experts on their own child. He has cared for children who are parents themselves today, and Marquis MD now lets him give every family the unhurried time and steady continuity that pediatrics has too often lost.

Pamela Westberg is a seasoned healthcare executive whose 20-year career spans concierge medicine, large health systems, and behavioral health. As Chief Operating Officer of Marquis MD, she brings a rare combination of operational precision, financial acumen, and people-centered leadership to one of South Florida’s premier concierge medicine practices.

Her Master’s degree in Industrial Organizational Psychology is the thread that runs through everything she does, translating the science of human behavior into real-world healthcare strategy, stronger teams, and better patient outcomes. This lens gives her an innate ability to see the full picture in any healthcare environment: the systems, the culture, and the human dynamics driving outcomes across the field.

Her practical experience spans concierge medicine, where she has guided practitioners from volume to value; large health systems, where she served as Director of Operations at Baptist Health South Florida and later as Chief Strategy Officer overseeing Florida’s mental health and opioid federal funding; and behavioral health, where she developed a deep understanding of what it takes to deliver care that treats the whole person.
