Dr. Giannatselis ND is passionate about supporting couples in their dreams of becoming parents. She believes it all begins with the egg and sperm and dedicates her time to supporting all processes that may be contributing to their quality. She empowers women with fertility concerns, and those focused on optimizing their health outside of fertility, to become knowledgeable of their health and advocate for best treatments.
Dr. Holly ND uses supplementation, nutrition, and acupuncture to create individualized treatment plans for each of her patients. As a practitioner at Omega, she is able to offer truly integrated care alongside a team of REIs.


Holly’s unique educational background paired with her personal experience as a mother has lead to her interest in women’s and paediatric health, primarily fertility, peri/prenatal care, and children’s health, however she enjoys working with the entire spectrum of health issues. This includes but is not limited to digestive health, food allergies, metabolic imbalances, weight management, and pain syndromes.
