Our Story

The partners who started LX Medical have over 30-years of experience that covers primary care, nutritional science and wellness, sports medicine, urgent care, and emergency medicine. We aim to bring all of our experience and innovation into an affordably priced concierge medicine experience. Healthcare is changing, reliable access to high-quality medicine for acute illness is strained, and we believe that the current (old) model has hurt both the medical providers and patients.


Our goal is to provide the highest level of convenience by coming straight to your home, or place of work, or hotel, or school, or cabin. Wherever you need us, we will be there. We only bring you exceptionally-trained medical providers so you never have to wonder if the provider taking care of you or a family member is as qualified as expected. You can never predict when you’ll be sick or injured, but with LX Medical you will know you’ll be covered when that happens.
