Meet The LX Medical Team



Co-Founder and Owner

Aundria Riggen has been working as an advanced practice provider for nearly 10 years.  For over 6 years she has been a leader in urgent/acute care medicine. She is dedicated to her patients and is very involved in teaching the next generation of medical providers. She was recently awarded “Preceptor of the Year” by St. Catherine’s University. She also spent 3-years in orthopedic surgery and is highly trained in medical procedures, joint injections, and musculoskeletal issues.

Aundria also believes feeling great goes hand-in-hand with looking your best. She is fully certified in BOTOX and Dermal fillers. She is dedicated to staying up-to-date in all things related to health, beauty and wellness.

A mother of two, she understands just how frustrating the healthcare system can be, both for herself and her kids, to get fast, reliable, and quality medical care. She’s finally doing something about it through co-founding LX Medical alongside her husband.



Co-Founder and Owner

James Riggen has been an advanced practice provider for 10 years, 8 of which has been dedicated to emergency medicine. From Level-1 trauma centers to rural critical hospitals, he has experienced the full spectrum of acute care medicine.  He strives to give the highest level of medical care alongside a top notch bedside experience.  James worked for 18-months in pediatric neurology, and 18-months in general surgery, as well.

Outside of the specialty of emergency medicine, James has thoroughly enjoyed applying his original undergraduate degree in Nutrition and Food Sciences to IV Therapy and all its benefits from faster recovery from acute illness, to day-to-day peak performance and anti-aging. 



Nurse Practitioner

Teal Foster is a Family Nurse Practitioner who holds her Doctor of Nursing Practice from Augsburg University. She has served in a variety of settings including Family Practice, Sports Medicine, Prenatal Care Services and Telehealth.
