Fernando A. Lopez Osma, MD, FASN

Dr. Fernando Lopez is originally from the small city of Bucaramanga in the eastern part of Colombia, South America. Both of his parents are physicians so his exposure to medicine was very early in life. This allowed him to observe and learn from his own parents to care for those who are in need. Because of that, Dr. Lopez always dreamt of becoming a doctor.

After finishing high school in Colombia, Dr. Lopez spent one year as an exchange student in Athens, Ohio where he was able to understand the American culture.  This allowed him to dream of a career in the United States.

Upon his return to Colombia, after his exchange student year, Dr. Lopez was blessed to be admitted to his home town medical school, Universidad Industrial de Santander, where his parents attended. It was a pleasure to follow in his parents’ footsteps. During his last year of medical school, he decided to follow his own path.  Dr. Lopez completed a research rotation at Johns Hopkins University in Baltimore, which introduced him to the practice of medicine in the US. It was then that he decided to start the process of applying for residency in the US.

Dr. Lopez completed his Internal Medicine Residency and Nephrology Fellowship at Maine Medical Center in Portland, Maine. His training allowed him to advance his medical knowledge and become an expert in treating patients with kidney disease. Dr. Lopez was drawn to specializing in Internal Medicine and Nephrology early on in his training because of the human physiology and the art of practicing medicine involved. Nephrology gives one the option of using the latest technology to improve the quality of life of patients and play an important role as a partner in their health.

Dr. Lopez is board certified in both Internal Medicine, Nephrology and Hypertension. He focuses his care in developing an exceptional relationship with his patients and their families in order to improve their health as a team.

As a clinician, Dr. Lopez’s areas of interest include the development and use of educational tools for patients and families to improve their understanding of their diseases. As a nephrologist, his areas of clinical interest include resistant hypertension, CKD, home dialysis therapies and education to students, residents and colleagues.

When not practicing medicine, Dr. Lopez spends the majority of my time with his lovely wife and 2 small children (a 3 year old and a 1 year old), either at home or traveling to new places and experiencing new cultures. He enjoys playing soccer, tennis and swimming. He also loves biking and using technological gadgets.
