About us

The bridge to better health

The Dauphin Island Medical Group is comprised of Tessie L. O’Quinn, CRNP, Marcie McPhillips, CRNP, and Jun Yoo, DO. The concept for the clinic was originally envisioned by Tessie O’Quinn CRNP with the hope of providing Dauphin Island and the surrounding communities with optimal, efficient, and effective health care to allow members to live their best, healthiest lives.

Through the generosity of Mayor Collier and the city council, we were granted a home. On February 14, 2023, we opened the doors at 1008 Alabama Avenue, just behind Town Hall. Dauphin Island Medical Group has the best housemates ever in the Public Safety Office. A marriage made in heaven, together we can address the health needs of the Island.

The Dauphin Island Medical Group is a grassroots effort and heavily reliant upon the participation of our community members in order to grow.  We would like to express our limitless gratitude to the volunteers and donors who have allowed us to serve this community. This clinic is not our clinic… it is the community’s clinic. We cannot take care of you if there is no you. We appreciate being a part of the community. Please contact us if you are interested in volunteering or making a donation

For the time being we are open Tuesdays and Thursdays and offer clinic, telemedicine, and home visit appointments by request on other days. As our business grows, we look forward to expanding our availability. Available services include primary care, acute care visits, routine physicals, lab work, IV infusion therapy, B 12 injections, salt therapy, and periodic special events.

Payments currently accepted are fee-for-service/cash, United Healthcare, Cigna, Aetna, and some Blue Cross/Blue Shield. Medicare, Medicaid, Tri-care, and Humana are pending at this time. We also offer a Health First membership that waives co-payments, allows free admission to special events, home visits at no additional cost, priority appointment scheduling, and discounts on our IV and salt therapy services.

Our team

Tessie O'Quinn

Co-Founder/ CRNP

Tessie grew up in the New Orleans area and spent her summers with family in Fairhope, Alabama. At the age of 16 she was accepted into the class of 1989 at the Louisiana School for Math, Science, and the Arts. After completing high school, she moved to Baton Rouge, where she majored in psychology and minored in sociology. After graduation she was employed with a company that provided addiction and mental health services. She later returned to nursing school, where she discovered a passion for critical care nursing. She worked as a nurse in Baton Rouge and Charleston, SC, before landing in the Mobile area.

In 2011 Tessie returned to school, earning a master’s degree in nursing. She is certified in two specialties: Family Practice and Adult-Geriatric Acute Care. Since graduating she has worked in pulmonary, critical care, correctional, and internal medicine/acute care settings. While she has always loved working in a hospital setting, she realized that another passion was calling to her. Tessie moved to Dauphin Island in 2007. Soon after moving to the Island, she felt a desire to serve the community. In early 2022 the Dauphin Island Medical Group was formed. Tessie feels strongly that everyone deserves timely and thoughtful medical care that addresses the whole person: body, mind, and spirit. Her group intends to integrate yoga, meditation, mental health, and nutrition into conventional Western medicine in order to address clients’ needs. 

Outside of healthcare, Tessie shares her love of nature with her spouse, Brian Jones. She combs the beaches to find “treasures” from which she often makes jewelry. She has enjoyed practicing yoga since first discovering it in 1995, in Baton Rouge, and loves to introduce others to the practice.

After graduation, he completed his internship and residency at Sacred Heart Hospital in Pensacola, Florida, where he served as Chief resident of internal medicine. Dr. Yoo is board certified in Internal medicine.

Outside of medicine, his interests include fishing, hunting, tennis, and golf. When asked how he feels about Dauphin Island, he responds “I love everything Dauphin Island has to offer and am looking forward to making Dauphin Island my home in the near future.”

Marcie McPhillips

Co-Founder/ CRNP

Marcie grew up in Bay St. Louis on the Gulf Coast of Mississippi. She graduated high school from Our Lady Academy and majored in Psychology at the University of Mississippi. She moved to Mobile, Alabama with the intention of receiving her Master’s & PhD in Psychology but instead married her husband, Tom, who was born and raised in Mobile. They became Part-Owner of the South East Restaurant Franchise for Zoe’s Kitchen while opening their first location from the ground up in Destin, FL followed by their second location at Legacy Village in Mobile, AL. 

After selling the franchise ten years later, Marcie was being drawn to serve and help others in a more profound way through the advocation of Nursing. She received her Bachelor’s of Nursing from the University of South Alabama in 2012. She started her nursing career in the Neuro Intensive Care Unit at Mobile Infirmary where she led stroke codes, advanced cardiac life support, and other emergent situations. After the birth of her son and daughter, she expanded her Critical Care experience by working in the Cardiac, Surgical, & Medical ICU at Mobile Infirmary while completing her Master’s Degree of Nursing in Family Medicine with a 4.0 GPA from Walden University in 2017. 

Marcie has been working at Springhill Memorial Hospital since becoming a Certified Nurse Practitioner where she utilizes her critical care skills in diagnosing medical problems that require immediate treatment, promptly implements a medical treatment plan and safely guides patient care. “I am beyond proud to be a Nurse Practitioner. It has been the most rewarding blessings of my life to be able to give a part of myself and truly be able to make a difference in the lives of others. Nursing or any part of the medical field is not a job. It is a calling”. 

Outside of Medicine, Marcie is an avid equestrian, enjoys fishing, loves being a mother, wife, and spending time with her family and taking care of the 18 animals on her farm!
