Twin Valley Holistic Health & Wellness will welcome Barbara O’Neill, a globally respected health educator, back to Lancaster this fall for Self-Heal With Barbara O’Neill, a five-day wellness series designed to inspire, educate and empower. The event will take place at Lancaster Mennonite School from October 14 through 18, 2025, with weeknight sessions from 5 to 8:30 p.m. and a Saturday session from 8 a.m. to 2 p.m.

O’Neill is known worldwide for her holistic approach to health, which combines science, nature and scripture to help individuals understand the body’s innate capacity to heal. This year’s series will feature brand-new material alongside essential teachings on detoxification, gut and lymphatic health, and lifestyle medicine. Whether new to O’Neill’s work or returning for deeper insights, this event offers a unique opportunity to learn directly from one of the most trusted voices in natural wellness.

In addition to the lecture series, attendees can explore the curated Blue Door Merc & Perc market, available in person each day of the event. The market will feature specific items aligned with the topics O’Neill discusses in her lectures. For ongoing access to O’Neill-endorsed books, tools and natural remedies, attendees are also invited to visit Shop Blue Door, the sister business’ online store, at TwinValleyHealthAndWellness.com/shopbluedoor.
