Katherine Novotny

Core Faculty

A self-portrait of Katie Novotny would look like a colorful octopus lady (probably with fairy wings) adorned in an experimental vintage wardrobe with each arm holding plants, tincture bottles, ceramic sculptures, crystals, records, a deck of cards, a novel, and a smudge stick. She comes from a long line of green-thumbed, strong female influences and has admired grandmothers for as long as she can remember.

Katie Novotny is a Clinical Western Herbalist with a certification in counseling, and has been seeing clients since 2011.  In consultations, she works with each individual’s unique case, and formulates herbal, nutritional, and emotional treatment to help her clients heal from their dis-ease. After each consultation, Katie takes the time to track each of her client’s progress and keeps a detailed record of the content in each session. Seeing clients is one of her passions, and is confidant working with all kinds of health concerns: emotional/physical/spiritual. She is currently teaching the “Foundations” class for the OHC in San Francisco.

When she’s not at the Ohlone Herbal Center, you could find her thrifting at yard sales, camping in her old Nissan truck, or in her backyard gardening, pruning fruit trees, or wrangling chickens.

Kelsey Barrett

Director of Operations, Faculty

Kelsey’s connection to community health arose while crafting legislation with New York City Council’s “Committee on Women Issues”.  Cooperatively working with councilwomen to pass New York City’s first legislation for women of color with HIV instilled in her the possibility of large-scale health care change.  Kelsey’s approach to health transformed on a pilgrimage to France where she studied with the herbalist and scholar Matthew Wood and flower essence master Julia Graves, in 2009.  This experience oriented her to nature as the primary source of healthcare.  Upon returning from France she co-founded an herbal gathering “Heavy Nettle Collective”, which presently holds monthly workshops in Los Angeles hosting local and national plant healers.  Continuing her education, Kelsey graduated from Ohlone Herbal Center as a Clinical Western Herbalist, where she applied her knowledge in a community clinic setting.  Kelsey currently works as the Director of Operations at Ohlone Herbal Center and has an active herbal practice.  She believes embracing plants as part of our larger community gives us greater opportunity to reconnect in meaningful ways.

Krista works to support the individual and community awakening of our ancestral knowledge thru the practice of connecting to the plants, animals, rivers, and mountains around us for healing.

Growing up in the Ohio River Valley, partnered with an innate empathy and curiosity of the wonders of this world, instilled a love of plants, animals, astronomy, music, and dance.

Elizabeth Migliorelli


The first time I came to California I was under the spell of the scent of the Eucalyptus along the coast. I hail from the brown deciduous woods of New York and the Evergreen forests of the Pacific Northwest, and the sweet, stirring smell of Eucalyptus was something I had never experienced before. Although I love my trees from my various homes, the eucalyptus was something that was so intoxicating, so bewitching to my spirit, that I knew I would have to spend some time getting to know this area of the world.  I became an herbalist through my own healing crisis as well as a frustration with the loss of ancestral wisdom and privatization of health care in this country. I was no longer willing to be disassociated with my body and this earth. I don’t believe that health comes from sterile doctor’s offices, instead I believe in the magic and healing that comes out of our own kitchens and homes. I have always welcomed folks into my kitchen. It’s a place where we can cook community dinners, enjoy the practical magic of fir tip and wild strawberry leaf tea, or to just sit on the floor while sharing space and telling stories, whether they are painful or pleasant. These are practices that nourish myself as well as my community and I am dedicated to encourage others to empower themselves by taking care of themselves! When I’m not working at the lovely Ohlone Clinic, I spend a lot of my time harvesting plants, infusing medicinal honeys, laying down on the forest floor, making flower essences, reading about and connecting to ancient folklore and magical practices and striving to maintain seasonal balance within myself. Let’s continue to take good care of ourselves!

Ella Gluckman

Administrative Assistant

All my life I have desired a homecoming, which I intuitively knew would come with a reverential and reciprocal relationship to the wild. I grew up in Pittsburgh, PA, a homey straightforward steel town where medicine was practical and allopathic. As a kid, I knew that creativity and health were one, that community was intrinsic to wholeness. I felt most vibrant when I was hanging out with trees, writing my stories, and learning the truth from teachers past and present. I came to study herbal medicine after many years of desiring to commune with plants and a desire to know more of the art of health from my ancestors. I am so grateful to serve the various communities here and to partake in the luxuriousness that is plant medicine. When I am not working at the Ohlone Herbal Center or seeing clients here, you can find me swimming in a river, hanging with plant friends, making medicine, reading, writing, dancing or playing music.
