Aaron M. Bernie, M.D., M.P.H.

Dr. Bernie

Dr. Bernie earned his medical degree and masters of public health from Tulane University School of Medicine and completed his residency training in urology at New York Presbyterian-Weill Cornell and Memorial Sloan Kettering Cancer Center.

Dr. Bernie practices all aspects of urology, including minimally invasive & robotic urologic surgery, urologic oncology, prostate, kidney and bladder cancer, endourologic treatment of kidney stones and BPH, male infertility (including microsurgical treatments), and erectile dysfunction. Dr. Bernie is board eligible with the American Board of Urology.

Dr. Bernie was a SMRU Traveling Scholars Program Award Recipient in 2014. He was also a Andlinger Fellowship Recipient in 2015 and was a Ferdinand C. Valentine Essay Meeting Award Winner in 2016. He has numerous publications and book chapters on the topics of urologic oncology and infertility, and has presented at international urologic meetings.

Many years of training have given me the ability and privilege to treat my patients and their urologic conditions. I have been fortunate to complete my residency at two of the top centers in the world for many urologic conditions, including minimally invasive and robotic treatment of urologic cancers, endourologic management of kidney stones and BPH, as well as microsurgery for the treatment of male infertility. I believe that as much as medicine is a science, it is also about knowing your patients, and treating them as individuals. Every patient deserves the care and attention to detail that I strive to provide in my practice, and no two people or their urologic conditions are the same. My goal is to provide each one of my patients with the personalized care that they need, and make sure that they not only understand, but also participate in their treatment plan.

Approach to Healthcare:

To treat my patients with respect and compassion; to empower my patients with knowledge and enable them to be equal parties in their healthcare decisions. When not providing healthcare, I enjoy spending time with family, friends, husband and our dogs, as well as traveling, hiking, and reading.
