Kathleen Chesney, RN

Kathleen Chesney, began her healthcare career as an RN and loved caring for patients. I moved to Redding in 2000 and continued working in cardiac care, then in the cardiovascular intensive care unit recovering open heart patients. I returned to school at Simpson and graduated with my Bachelors Degree in 2005, the first year they became a University. I continued nursing as I went to the University of California Davis and completed the Physician Assistant Program.

I wanted to have more impact on my patient's lives and I wanted to show them that quality healthcare can be delivered compassionately. I want patients to be able to feel genuine warmth and trust when they come to see me, as I feel it makes us work better as a team. Our team here is exceptional and I look forward to meeting my new patients and helping them to live their best lives.

Dr. Arjana Shakya is a compassionate and dedicated physician, committed to making a positive impact on her patients' lives. After completing her medical education, she served as an ophthalmologist in her home country, Nepal, for seven years. During this time, Dr. Shakya had the privilege of restoring vision to over 10,000 underserved individuals, an experience that deeply influenced her commitment to patient care.

She completed a three-year residency at Brookdale University Hospital Medical Center, an inner-city safety net hospital serving a diverse and historically disadvantaged population. As a frontline worker during the pandemic, she witnessed firsthand the resilience of her patients and the critical importance of compassionate care. This period not only honed her medical skills but also reinforced her belief in the value of humanity and gratitude.

Dr. Shakya believes that being a good human is essential to being a good doctor. She strives daily to be empathetic and a great listener, qualities her patients frequently commend. She feels blessed to have the opportunity to help people every day and is committed to continuing her journey of personal and professional growth.

Outside of her professional life, Dr. Shakya is a proud mother to a seven-year-old daughter, who inspires her with courage and a thirst for learning. Dr. Shakya has a passion for travel, aiming to explore at least one new country each year. She also enjoys adrenaline-pumping activities like bungee jumping and looks forward to skydiving in the near future.

Dr. Shakya's journey from Nepal to the United States and her experiences as an ophthalmologist and internist reflect her unwavering dedication to medicine and her patients. She continues to strive for excellence, guided by her belief in empathy, compassion, and the joy of helping others.
