SHELTON, WA – This summer, Mason Health welcomes three new primary care providers to Mason Clinic, as well as a new specialty care provider to Mason Clinic-Women’s Health. These providers bring a wealth of expertise and a dedication to preventative medicine to Mason Health. Join us in welcoming Jacqueline Gorzynski, MD; Tiffany Henningsen, ARNP; and Alyssa Sethi, DO to Mason Clinic-Primary Care, and Kym Walker, MD, to Mason Clinic-Women’s Health. Later this year, Mason Clinic-Primary Care will also welcome new provider Tanveer Sidhu, MD, to the team.

Mason Clinic-Primary Care:

Dr. Gorzynski was born in Phoenix, Arizona, but has spent her life in the rural Pacific Northwest. She grew up in Rochester, Washington, and completed her undergraduate education with a degree in exercise science at Willamette University in Salem, Oregon. She graduated from the University of Washington School of Medicine in 2021 and completed her residency training at Chehalis Family Medicine in 2024. As a full-spectrum family provider, she is eager to provide care for the whole family. Her special interests include addiction medicine, lactation, trauma-informed care and women’s health.

Henningsen, ARNP, worked as a registered nurse at Mason General Hospital for more than 10 years when she decided it was time to create a new path for herself in health care. Henningsen is from the Mason County community, and she loves being able to serve the community where she lives. Her focus is to provide primary care to patients of all ages, while keeping her foundation as a nurse. She looks forward to this new journey and cannot wait to make an impact in the lives of patients. She enjoys family life with two children, a beautiful horse Fae and Stuart the goat.

Dr. Sethi is a dedicated family doctor committed to providing compassionate and personalized health care. She specializes in medicine, women’s health and pediatric care. Dr. Sethi prioritizes building strong relationships with her patients, focusing on holistic wellness and evidence-based treatments. Outside the clinic, she finds joy in running, hiking and exploring new destinations through travel. A lifelong dreamer of moving to the West Coast to immerse herself in the Great Outdoors, Dr. Sethi brings her passion for adventure and healthy living into her practice, ensuring each patient receives comprehensive care that aligns with their individual health goals and needs.

Mason Clinic-Women’s Health:

Dr. Walker grew up in the Pacific Northwest and graduated from Stanford University with a degree in Human Biology. She then joined the US Peace Corps and traveled to The Gambia, West Africa, where she focused on maternal and child health. After college and the Peace Corps, she knew that she wanted to empower and support women. She attended University of Rochester School of Medicine, graduating in 2003, specializing in obstetrics and gynecology in order to support women through many of their most life-defining and impactful moments in their lives. When not working or spending time with her husband and three teenagers, she loves reading and running, and taking her two dogs for walks.
