Bret Pasiuk

As a nephrologist, Dr. Pasiuk sees patients with kidney-related illnesses and helps them effectively manage their specific needs relating to kidney disease. He provides primary and consultative services to patients with a variety of kidney-related conditions, including: acute and chronic kidney failure, diabetic kidney disease, fluid and electrolyte disorders/management, glomerulonephritis, hematuria, hereditary kidney disease, cystic diseases of the kidney, hypertension, medical management of recurrent kidney stones, proteinuria and renal transplant follow-up.

“My goal is to see patients early enough to prevent or delay dialysis,” according to Dr. Pasiuk. “I provide care that focuses on my patients and their specific needs.” “I enjoy practicing at Agnesian HealthCare and the quality of life that this community offers,” he adds. “Agnesian HealthCare providers and associates work very closely together, which makes communications between providers easier and gives the opportunity for us to continually improve the quality of life for our patients.” Dr. Pasiuk and his wife, Joanne, live in Fond du Lac. They have two children. Dr. Pasiuk also has two older children who live and work in Washington D.C. Dr. Pasiuk enjoys spending time with friends and family, and he loves Thanksgiving because it is filled with family and food.
