Born in Taipei, Taiwan, and raised in the small town of Berkeley Heights, New Jersey, Dr. Fang’s career path in medicine was realized at an early age as he witnessed the healing works of his father and grandfather, both of whom were physicians. He attributes his choice to specialize in GI to his impressive mentors during his residency as well as his inquisitive nature to solve problems, treat patients and to perform technically challenging procedures. Like the early knowledge of his career path in medicine, Dr. Fang knew he would return and call Reno home one day after a brief trip during college when he stopped through the city on the way to Lake Tahoe. Dr. Fang settled in Reno in August 2015.

Dr. Fang practices all aspects of general gastroenterology and hepatology with special clinical interests in pancreaticobiliary diseases. Additionally, he enjoys performing advanced diagnostic and therapeutic endoscopic procedures, endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreaticography (ERCP).

Dr. Fang strives to practice professionalism, thoroughness, empathy and compassion as he believes that the foundation of world class medical care is based upon a positive partnership between physician and patients. His passion for his career in medicine drives him to continually think of ways to improve the outcome of current endoscopic techniques, developing new endoscopic procedures, medical device development and quality improvement to improve safety for patients.

Outside of work, Dr. Fang enjoys spending time with his wife and three young children, traveling, learning about history and culture and exploring all the outdoor activities such as biking, snowboarding, hiking and camping that Northern Nevada and Northern California has to offer.

Amie served 10 years of her nursing profession since graduation in the Philippines. She had the opportunity to continue her nursing career in the UK for 6 years and eventually moved to the US in 2006. Most of her professional experience is in critical care.

She found the passion of empowering patients and their families in their health journey through education. Knowledge is power, and the more knowledge or understanding that those patients and their families have or received, the more they become empowered with the choices that they make.

GI conditions are complex, and a lot of patients have a tough time balancing a healthy quality of life. She wants to be there to listen to her patients on their health journey, establish a good relationship, respect every culture and be an advocate for a healthy well-being for patients’ best interests.
