Welcome to the clinic of Dr. John O’Mahony. Dr. John O’Mahony is a family physician in Sarnia with a comprehensive medical practice. We pride ourselves on the wide scope of services that we provide to our patients, reducing the number of referrals we need to make. We also provide care for our patients when they are in hospital, which is often when they need their family doctor most. Our team works hard to ensure that thorough exams are performed at every visit and all issues that patients want to address at a visit are taken care of. We do not follow the “one problem per visit” philosophy. Read more
