Jessica Matis


I received my Doctorate in Nursing as an Adult Care Nurse Practitioner from the University of Kentucky, in 2015. Since then, I have specialized in Adult Care treating a wide array of illnesses and diseases. Throughout my career I have found my greatest passion in treating hormonal imbalances in both men and women. My husband and I have both experienced the frustration of going to our Primary care provider with symptoms and being told “our labs are normal” and “we are healthy”, even though we did not feel good. We both feel passionate about Optimize U and what it has to offer the community in and around Louisville. I make it a priority to treat patients like family and base care on symptoms and not just numbers alone.
