Brandi L Sakai, MD
Commander, USN
Board Certified Emergency Medicine Physician
Born in Welsh, Louisiana, on June 6, 1981, Cmdr. Sakai grew up with a passion for science and the ocean. After graduating from the Louisiana School for Math, Science, and the Arts in 1998, she pursued marine biology, studying diverse ecosystems from the marshes of Louisiana to Scotland’s marine mammals and the vibrant reefs of the Virgin Islands. Her work at the Roy L. Schneider Hospital’s barometric pressure chamber sparked her drive to combine science with service, graduating cum laude with a B.S. in Biology.
In 2005, she commissioned in the Navy through the Armed Forces Health Professions Scholarship Program (HPSP) and began medical school at Louisiana State University Health Sciences Center. Hurricane Katrina hit during her training, and Commander Sakai worked tirelessly in pop-up clinics, providing care and vaccinations to displaced communities. This experience shaped her dedication to serving others in times of crisis.
Her Navy career has been marked by leadership and innovation. From integrating Marine medical services in Japan to creating advanced training programs for shock trauma care, she has consistently raised the bar for military medicine. As the Senior Medical Officer in Okinawa and later the Department Head of Emergency Medicine in Guantanamo Bay, she improved operations, ensured top-tier care, and earned recognition for her commitment to excellence.
Beyond her professional achievements, Commander Sakai is a certified Emergency Medicine Diplomate and a devoted wife and mother of two. When she’s not scuba diving, sailing, or baking, she’s embracing projects that reflect her passion for problem-solving and innovation.
Reflecting on her career, Cmdr. Sakai shared, “I had many jobs that many would consider a career. I was a PADI scuba instructor and manager of the storefront of a tour operation in St. Thomas US Virgin Islands (USVI). If you took a cruise to the island, you walked past our store on the docks. We may have said hello two decades ago! After doing the job for 5 years, I felt that I had learned all that I could, and there was no chance for advancement based on performance, so I knew that I needed something new and challenging. After getting my degree in Marine Biology and presenting environmental research to the Senate on USVI fisheries and the impact of hotel expansion, I realized that I enjoyed talking and educating people one-on-one, and speaking to rooms and presenting posters wasn’t going to make me happy. I volunteered at the local Emergency Department, and the variety and mental challenge of solving a puzzle on every patient kept me coming back. I decided to turn it into a career, but I also hated to stay in one place (there was a big wide world to explore), so I joined the Navy and never looked back. I did a General Surgery internship, and the Chaplain and I were the only Naval Officers in my first duty with the Marines in Iwakuni, Japan for 3 years. Being part of the Marines for 3 years to start my career really shaped me and set the tone for all my OCONUS tours since. My husband was an Ombudsman and found a great career as a financial educator that allows him to work virtually. If you need advice on mainland Japan, Korea, Okinawa, or Guantanamo Bay, or love medicine and want to explore your options give me a ring.”
Meagan G. Chauvin, MD, FACOG
Lieutenant Commander, USN
Director of Medical Services/Staff Attending OBGYN
A Houston, Texas native, Lt. Cmdr. Meagan Chauvin has built a remarkable career in military medicine. After earning her Bachelor of Science in Chemistry with Distinction from the U.S. Naval Academy in 2010, she completed her Medical Doctorate at the University of Texas Medical School at Houston in 2014. She completed her Obstetrics and Gynecology residency in 2018 at Naval Medical Center San Diego.
Her first assignment as a staff OB/GYN took her to Naval Hospital Guam, where she led the OB/GYN Clinic as Department Head and earned Board Certification in Obstetrics and Gynecology. Later, at Fort Belvoir Community Hospital in Virginia, she became Department Chief of the Women’s Health Clinic, further demonstrating her leadership and dedication to women’s health.
Now serving as the Director of Medical Services at Naval Hospital Sigonella in Italy, Lt. Cmdr. Chauvin continues to lead with excellence. Among her awards are the Defense Meritorious Service Medal and the Navy and Marine Corps Commendation Medal.
Lt. Cmdr. Chauvin is also a proud wife to Matthew Gerard Chauvin and mom to three children—EJ, Madeline, and Ellie—balancing her professional success with a fulfilling family life. Reflecting on her career, LCDR Chauvin shared, “I was inspired to become an OBGYN, because I loved taking care of women across their lifespan and developing long-term relationships with my patients. In addition, I love welcoming babies into the world and being part of helping patients grow their families. I joined the Navy after being inspired by classmates from high school who also went to service academies. The Naval Academy was an amazing experience that led me to the most important job I can imagine, supporting Navy women and families as an OBGYN. I am proud to follow in the Navy tradition of my great grandfather, who served on a troop transport ship in WWI, and my grandfather, who joined via the Navy V-12 program during WWII.”
Kristen Shafer, MC
Lieutenant, USN
Emergency Medicine Attending
Born in New York, New York, Lt. Shafer discovered her passion for science and outreach early in life. After earning her bachelor’s degree in chemistry pre-medicine at Indiana University of Pennsylvania in 2014, she brought the wonders of chemistry to life for local elementary students through her self-created Chemistry Magic Show.
In 2015, she pursued her Master of Science in Space Physiology and Health at King’s College London, where her thesis explored visual function and impairment in dynamic environments. She collaborated with the United Kingdom space program’s Mission X initiative, blending her love of science with public engagement.
Lt. Shafer joined the Navy through the HPSP program and earned her Doctor of Medicine from Stony Brook University in 2020, graduating early to assist with the initial surge of COVID-19 patients in New York. She went on to complete her Emergency Medicine Residency at USNMRTC Portsmouth in 2024, where she expanded Science, Technology, Engineering, and Math (STEM) outreach programs, inspiring over 300 high school students annually.
Now an Emergency Medicine Attending at USNMRTC Sigonella, Lt. Shafer continues her commitment to both medicine and mentorship. As Emergency Response Committee Chair, she oversees emergency preparedness, and as a liaison to local DoDEA schools, she is developing a mentorship program to introduce students to healthcare careers and military opportunities.
With a passion for outreach and academic medicine, LT Shafer embodies the Navy’s mission to serve both on and off the field, inspiring the next generation of leaders. Reflecting on her career in emergency medicine, Lt. Shafer said, “In emergency medicine, we need to be ready for whatever comes in the door at any time. Military medicine lets me practice that medicine and be comfortable providing care not just at any time, but any place in the world and to a population that is dedicated to serving others and making a difference.”
