Welcome to Lakeside Pulmonary Medicine
Dr. Corey O’Brien, D.O., FCCP
Deacon Kimberly O’Brien, M.Div., BCC
Corey and Kim met as teenagers and their mutual love of the lake brought them together. They built a relationship in spite of attending different schools and supported one another through the long journey of undergraduate, medical school for Corey and graduate school for Kim. They’ve been married for over two decades and have three children. Corey has been working in healthcare starting as a nurse aide from the age of 16 and always knew he wanted to be a physician. Kim began her career as a chemical engineer, was a stay-at-home mom, then went to seminary to become an ordained minister and chaplain. They have enjoyed Saint Joseph as visitors for the past 17 years and decided to make it their permanent home as they sought a lifestyle change from their current roles within conventional healthcare systems. When they are not engaging their passion for caring for others, they enjoy walking the beaches of Lake Michigan, reading, and spending time with family.
