About Your Instructor

Holly Brandenberger

If you're ready to feel empowered and confident around essential oils & holistic health then you're in the right place!

I'm Holly, Registered Nurse and Certified Aromatherapist living near Seattle, Washington on my family farm. I received my Bachelor’s of Science in Nursing in 2006 from Marquette University and have worked in a variety of nursing specialties including trauma, burns, post-surgical, endoscopy and hospital administration. I discovered aromatherapy in 2015 and loved how aromatherapy can strengthen the mind-body connection and initiate a relaxation response.  I became certified through the School for Aromatic Studies and have been expanding my education ever since through specialized courses in utilizing aromatics for stress, trauma, and emotional wellbeing.

I am the founder of Science of Essentials, an online educational platform providing aromatherapy and holistic health education worldwide. I am the author of the bestselling book Aroma Alchemy, available worldwide, where I teach others how to use aromatherapy with confidence and intention. I also teach aromatherapy certification courses through The School for Aromatic Studies and currently collaborate with hospital systems to bring aromatherapy to the bedside in support of patient care. My deepest desire is to share the knowledge I’ve gained by bridging modern medicine and holistic health to serve and support others.
