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.

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.

I am a Nevada native that has lived all over the state until settling in Reno in 1995. I now live in Sparks with my wife and two children. I have been in GI nursing for the past 6 years and look forward to furthering my GI journey as an NP. I feel that gastroenterology is an important piece of a persons’ overall heath and it is one of the aspects of healthcare that can often go unaddressed until it is too late. I hope to educate my patients about the importance of GI health and treat those in need.

Outside of work I enjoy spending time with my family in activities such as camping, fishing, hunting and riding motorcycles.

I am a native Nevadan. I went to High School in Carson City and then went to UNR for my Bachelors of Biology Degree. After my graduation from UNR in 2000, I moved to Los Angeles to pursue my Masters Degree as a PA-C. Upon graduation in 2005, I moved to Denver Colorado and stayed until 2020 when my family and I moved back to the Silver State. Home means Nevada!

In High school, I was diagnosed with a bone tumor that needed surgery. I fell in love with the medical team that cared for me, specifically the PA-C of the practice. It was from then on that I knew I wanted to work in medicine as a Physician Assistant and help others.

I am interested in helping patients with Hepatitis. While working in Correctional Medicine in Colorado, I had a passion for helping patients with Hepatitis C exposure and treatment.

I have been married since 2011 and have 2 wonderful children. In my free time, I play electric bass guitar in a band and am on a recreational ice hockey team. In addition, I love to hike, golf and ski in Northern Nevada.

Jeannie is one of our first hospitalist nurse practitioners for GI Consultants, joining the practice in 2020. She comes to Reno from Montana, but she grew up as an Air Force “brat,” having lived all over the country, including Maine, Nebraska, Texas, Colorado, and Montana. In 2008, Jeannie acquired her Nurse Practitioner’s license from Montana State University and began working in gastroenterology. She brings over eleven years of experience in gastroenterology and another year of experience in addiction medicine.

With all of her experience working in gastroenterology, Jeannie’s clinical interests are in Hepatitis C and chronic liver disease, but she enjoys all aspects of the gastrointestinal system and liver health.

Jeannie originally left Montana because she wanted new mountains to explore – with two college-aged children that were tired of the ice and cold, they packed up and joined us here in Reno. Jeannie and her family enjoy hiking, riding ATVs, playing Bingo, and going to rock and roll concerts!

I am a Nevada native from Fallon, have a comprehensive academic background and a deep commitment to patient care. I earned my Bachelor of Arts, Bachelor of Science in Nursing, and Doctorate of Nursing Practice from the University of Nevada, Reno, reflecting my dedication to advancing my knowledge and skills in the field of nursing.

My interest in the medical profession was sparked by a wilderness medicine course I took while working as a camp counselor at a summer camp in Colorado. This pivotal experience led me to pursue a nursing career, where I have since gained extensive experience across various nursing specialties. I am passionate about creating a safe and trusting environment for my patients, understanding that strong relationships are essential for effective health management and healing.

Outside of my professional life, I cherish the natural beauty of Northern Nevada, where I enjoy camping with my husband, two young children, and our dog. I also enjoy rock climbing, mountain biking, and natural hot springs. I find joy in cooking, creating art, and spending time outdoors, embracing the Sierra Nevada's scenic landscapes and vibrant activities.

After being raised here in Northern NV, I’ve spent the last few decades calling Reno my home.

I’ve always been fascinated with both medicine and the intricacies of the human body from a young age. After starting my first job in medicine as a CNA, I was introduced to the human element of medicine, where I discovered what it meant to care for those who could no longer care for themselves. It was after this that I sought a role that would allow me to blend both of these passions into one, and becoming a Physician Assistant allowed me to do just that. Many of the conditions we treat in GI may seem rather benign on the surface, but ultimately have the potential of really impairing one’s quality of life. Knowing this, I truly enjoy connecting with my patients on a deeper level and working together to promote their overall health while seeing them make strides in their own personal health journey along the way.

Outside of work I can be found pretty much anywhere outdoors. Whether I’m trying to lower my handicap on the golf course or fly fishing on the Truckee, as challenging as these hobbies are, this is where I’m most at peace.

Brynja Bowman grew up in San Jose, CA. She earned undergraduate degrees in art from Bard and UC Santa Cruz, her BSN in Nursing from Samuel Merritt University and her Adult Gerontology Acute Care Nurse Practitioner Master’s degree at UNR. Bryn worked as a nurse at the Kirkwood Ski Clinic and Saint Mary’s medical surgical unit for six years. Most recently she worked as a hospitalist and GI provider at Renown Regional Medical Center for the four years prior to joining GI Consultants. Bryn was drawn to the Sierras by her passion for snow sports and outdoor activities, especially snowboarding and camping. She, her husband Jason, and their son love to hike with their two dogs.

Mary is a native Nevadan, born and raised in Reno. She first attended the University of Nevada, Reno, where she attained her first bachelor’s degree in general studies with a focus on health. This is where she discovered her passion for healthcare, and soon after graduation she moved to Las Vegas to pursue a nursing career. In Las Vegas, she attended Roseman University of Health Sciences and received a Bachelor of Science in Nursing. Soon after, she returned to Reno to work as a nurse at Northern Nevada Medical Center. Mary was at NNMC for over 7 years as a nurse, during which time she returned to the University of Nevada, Reno, to obtain her Master of Science in Nursing and become a nurse practitioner.

Her passion for healthcare stems from her love of caring for and working with patients. She finds it rewarding to develop meaningful and engaging partnerships with both patients and colleagues to ensure safe and compassionate patient care and to help improve quality of life for the Northern Nevada population.

When Mary is not caring for patients, she enjoys exploring all the fun activities that Northern Nevada has to offer, especially with outdoor activities. She and her husband enjoy camping, hiking, kayaking, and fishing. When not in the great outdoors, she also enjoys reading, gardening, and discovering the great restaurants Northern Nevada 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. Taking care of the extremely sick patients in the ICU gave her the perspective that most of the causes of these critical medical conditions are preventable. 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.

Outside of work, Amie loves to cook, hang out with friends and families, and travel whenever she gets the chance.

Amie is seeing and accepting patients at the Reno-North office location on 880 Ryland St.
