Dr. Tyler Southwell

Dr. Tyler Southwell

Medical Director

Tyler Southwell, MD grew up wanting to be a village doctor, to develop relationships with patients, to spend time talking and listening to them. He received his BS in biological sciences and biochemistry and attended medical school at Wayne State University School of Medicine in Detroit and along the way found himself training to be a surgeon. His first residency was at the University of Toledo in urology, pediatric surgery, general surgery and plastic surgery. He soon realized that if he continued as a surgeon he would never have the chance to establish relationships with his patients, so he switched his focus and completed a second residency in the University of Michigan Family Practice Program.


A relatively recent transplant to Arizona from the Midwest, he originally came to work with Gila River Health Care and the Komatke Health Clinic in Laveen in January 2013. He currently is Medical Director for Arcadia Physicians Travel Clinic and works with Family Practice Specialists in Phoenix.


Tyler is married and has a beautiful daughter. He likes to work out and loves good food. Some of his favorite restaurants include Fifth and Wine, Chelsea’s Kitchen, LGO, and Postino’s. He loves movies, especially The Big Lebowski and Wes Anderson films, like The Royal Tenebaums. He is a fan of all kinds of music, including old school rock, country, blues and everyone form Elvis to Vampire Weekend and the Shins.

Dr. Southwell’s main ethos is that patients deserve respect. They deserve to be listened to and to know what is going on with them. He believes that treatment options should be a shared decision between a patient and a physician.

Travel Health Nurse Lauren Preble

Lauren Preble, R.N, B.S.N.

Lauren is Registered Nurse who has been with the Southwellness team since early 2020. She received her Bachelor of Science degree in nursing from Arizona State University in 2019. Prior to studying Nursing at Arizona State University, Lauren received a Bachelor of Science in Evolutionary Biology from the University of Arizona. This is where she learned to love all things related to infectious disease, immunizations, and global health. When the COVID-19 pandemic began, Lauren helped build some of the earliest programs in various community settings to provide patients with COVID-19 testing and access to medical care for sick patients. In early 2021, Lauren helped build a medical clinic in South Phoenix that continues to operate and serve asylum seekers when they first enter the US. When COVID-19 vaccinations first became available in Arizona, Lauren built a vaccination program to help give patients at our multiple medical operations access to COVID-19 immunization.

In addition to being a part of the Southwellness (and Arcadia Physician's Travel Clinic) team, she is also a Board Member with ProtectAZ Health, where she helps with advocacy efforts for improving access to medical care for migrants and asylum seekers. She is excited to continue to grow her expertise in the field of Travel Medicine and help educate patients on preventable infectious diseases as they prepare for travels around the world. 

Outside of work, Lauren enjoys creative endeavors, and is currently focusing on her guitar and piano. She also loves bike rides, sunny days at the park, trying out new foods, and dancing!
