Amanda’s career reflects a longstanding commitment to scientific holism and integrative healing.

Her connection to plants began early in life when she planted her first garden at the age of five, establishing a lifelong relationship with botanical medicine and the natural world that continues to inform her work today.

She remains actively engaged in professional aromatherapy organizations, supporting continued education, ethical standards, and the advancement of research and educational guidelines within the field.

She teaches this work through workshops, group classes, and private sessions, encouraging informed and sustainable personal practices.

As the creator of the Terracina aromatherapy line, Amanda formulates therapeutic products using high-quality botanicals designed to support mind, body, and spirit. The Terracina line emerged from her personal healing journey following the birth of her son. Drawing upon her background in chemistry alongside her training in herbalism and aromatherapy, she developed formulations intended to provide practical tools for holistic wellness and integrative self-care.

Amanda’s artistic work further explores the healing qualities of plants through color, botanical dyes, and energetic signatures. In collaboration with local artists, she creates botanically dyed wearable pieces that merge artistry with healing traditions. She also co-teaches workshops focused on botanical dyeing, plant energetics, intuitive development, and functional botanical applications.

A lifelong dancer, Amanda trained professionally in classical and modern ballet for 20 years, studying with influential instructors including Bernadette Clements, founder of the Northwest Florida Ballet.

Traditional Chinese Medicine, Martial Arts, Esoteric Practices, Coaching

David Tircuit is known to many Terracina clients through his longstanding acupuncture practice, Evolving Mind Body Healing Arts, in Portland, Oregon, as well as through his many years of martial arts teaching and training at One With Heart Fighting Arts on Hawthorne Boulevard. He holds a Bachelor of Arts in English Literature from the University of California, Berkeley and a Master of Acupuncture and Oriental Medicine (MAcOM) from the Santa Barbara College of Oriental Medicine. David is a licensed acupuncturist with more than 25 years of clinical practice in Portland and thousands of hours of patient care experience.

In addition to his work in Chinese Medicine, David has trained and taught Traditional Chinese Martial Arts for more than 40 years. His disciplines include Northern Shaolin Kung Fu, Taiji Quan, Xingyi Quan, and multiple styles of Qi Gong. He began his martial training under Master Peter Ralston at the Cheng Hsin School of Internal Martial Arts and Ontological Research, where he apprenticed from ages 11 to 18. From age 18 to 30, he studied under Grandmaster Wong Jack Man of the Jing Mo Chinese Physical Association in San Francisco, and also trained with Bagua master Zhou Chin Tsai.

David later co-founded the EBM Kung Fu Academy in Oakland, California, where he taught and co-directed the school for 10 years. From 2001–2002, he served as head of the medical Qigong program at the Santa Barbara College of Oriental Medicine. Between 2004 and 2020, he taught kickboxing, Qigong, Taiji Quan, Xingyi Quan, and Northern Shaolin Kung Fu at One With Heart Fighting Arts in Portland, Oregon.

Born in Oakland, California, during the cultural era known as the Summer of Love in 1967, David was shaped by the influences of both the hippie movement through his mother and the Civil Rights movement through his father. As a biracial practitioner raised within these intersecting cultural traditions, he brings a deeply integrative perspective to both his acupuncture practice and martial arts teaching. His work emphasizes inclusiveness, diversity, personal transformation, and continual evolution. The spiritual traditions of New Orleans Creole culture inherited through his father’s lineage continue to inform and influence his approach to healing and martial practice.

Alongside his martial arts and medical training, David’s longstanding interest in ontological research and esoteric studies has further informed his professional path. He continued these explorations through training in ontological kinesiology at Ad Humanitas in Portland, Oregon, and has extensively studied a wide range of religious and spiritual traditions. These experiences continue to enrich and deepen his practice of Traditional Chinese Medicine and Chinese Martial Arts.
