Sylla S. Hanger

ARC Board Member

Sylla Sheppard-Hanger is the Founder and Director of the Atlantic Institute of Aromatherapy in Tampa, Florida. She brings 45 years of experience and personal research into the practice of aromatherapy and essential oils.

Her fascination with this subject led her to study with the most knowledgeable scientists in the fields of aromatic and medicinal plants, essential oil research and herbology. In 1993, she completed the Medicinal and Aromatic Plants Program at Purdue University in Indiana, and she continued on to complete the International Training in Essential Oils: Advanced Studies, Parts 1 and 2 (1996-7). She was a founding member of the American Aromatherapy Association (1988) and served two terms on the Board of Directors. As former Chair of the Safety Committee with the National Association for Holistic Aromatherapy (14 years), she saw an influx of essential-oil-related injuries and began annual Injury Reports, which are available at the Atlantic Institute of Aromatherapy’s website.

After the September 11th tragedy, Sylla volunteered with the Carolina Emergency Relief Massage Team, whose four deployments provided complimentary chair massages and aromatherapy treatments to over 3,500 relief workers and volunteers. During this time, Sylla formed the United Aromatherapy Effort, Inc. (UAE) a non-profit charity with the mission to collect and provide donated aromatherapy products to those affected by critical incidents and emergency work. The UAE was active in Florida during the aftermath of the 2004 hurricanes, and they supported the community in Biloxi, MS, after hurricanes Katrina and Rita in 2005. Most recently, the UAE collected aromatherapy supplies for NATO soldiers in Camp Phoenix, Afghanistan.

Sylla is a licensed Cosmetologist/Esthetician, a Licensed Natural Health Care Practitioner and a Massage Therapist. She has provided introductory through advanced aromatherapy education since 1988 and has developed comprehensive educational programs that are presented throughout the United States. The Atlantic Institute of Aromatherapy is a Continuing Education Provider (Boards of Massage and Acupuncture) for the state of Florida, as well.

Sylla is the author of The Aromatherapy Practitioner Correspondence Course and The Aromatherapy Practitioner Reference Manual, the latter of which is a complete reference book with over 350 aromatic plant extracts and phytochemical, clinical and botanical indexes. Most recently, she began publishing her SBS Series, which includes the Aromatic Spa Book (2007) and the Aromatic Mind Book (2008). Since 1996, Sylla has also been involved with an on-going research project called Psychosocial Aromatherapy Research Project (PARP) with Dr. Trevor Stokes from the University of South Florida. The project studies the positive benefits of aromatherapy for children with autism and other disorders. She has also partnered with colleagues Dr. Robert Pappas, Martin Watt, and Tony Burfield for various academic papers and studies including the recent publishing of Tony Burfields second edition Natural Aromatics.

Besides teaching and mentoring students, writing aromatherapy articles for magazines and journals, Sylla also consults for private-label aromatherapy companies and other clients in need of her expertise. She volunteers her time and aromatic counseling skills to organizations within her community, and she continues to maintain her private aromatherapy practice in Tampa, Florida, where she resides with her husband and one cat.
