Marisa - Maggie Perkins 2017
IV Infusion Nurse
With 14 years of nursing experience, Marisa enjoys caring for patients at GMA because she feels like she is making a difference in a unique way and is able to give a little "TLC" on a person’s journey to wellness. "Sometimes people come in who have been through a lot physically and emotionally with an illness. They feel sick and sometimes apprehensive. I try to provide a place in our IV room where they can take a deep breath, listen to some pleasant music, and find a little hope. Often, our IV room is a place where patients support and connect with each other. It’s wonderful to see." Marisa and her husband and family have lived in Sonoma County for 9 years. She likes hiking, mountain biking in Annadel State Park, cooking, and getting lost in a good book.
Jenia - Maggie Perkins 2017
IV Infusion Nurse
Jenia has been a registered nurse for 30 years. Her background is in home infusion nursing, where she helped those suffering from AIDS, Cancer, and Lyme disease. She heard of Dr. Gordon over 15 years ago, and became a patient before joining his team of IV nurses. Jenia has worked with many doctors, but until she met Dr. Gordon, she had not found many who would truly listen to their patients. Dr. Gordon’s philosophy of healing has inspired her to pursue better health for her family and friends. She is grateful to be part of his team. She lives in Ukiah with her husband, dog, cats, chickens and goats. She enjoys taking care of her grandchildren, going on goat walks, fermenting foods, and gardening.
