About Stuart Sprague, DO
Stuart Sprague, DO, a nephrologist at Endeavor Health, brings decades of clinical experience and research to the care of patients with kidney disease. His work spans rare diseases, mineral metabolism and complex diagnostic challenges. Dr. Sprague is known for a patient-centered approach, especially for those who don’t fit typical treatment algorithms, and he continues to explore innovations in dialysis and artificial kidney development.
My endeavor
My endeavor is to approach every patient as an individual, try to deal with the problem they have, and come to a resolution together to improve their quality of life.
Care philosophy
Patient care must be individualized. I don’t believe in forcing patients into algorithms that may not fit. I address each patient’s condition in the context of their life, other health issues and overall wellbeing, using logical, physiology-based treatment to create the best plan for them.

Sad to see him retire

Dr. Sprague was great. He had thoroughly reviewed my file, and was well prepared for my visit. When I described the recent death of my spouse, he was appropriately sympathetic and expressed the same [...] sentiment that I have been feeling. He seems like a real human with whom I would like to have an adult beverage.

I have been under Dr. Sprague's care for about 3-4 years and have always found him to be caring, thorough, professional and relaxing, which put me at ease through my diagnosis and remission of Sarcoid. He and [...] worked well to coordinate my care...and they have released me from further care.
