Meet Our Weyauwega Dentist

William J. Twohig, D.D.S.

After an extraordinary 50-year career in dentistry, Dr. William J. Twohig has retired, leaving behind a legacy of innovation, compassionate patient care, and leadership in holistic and biological dentistry.

Throughout his career, Dr. Twohig dedicated more than three decades to researching and implementing alternative approaches to dental care that focused on each patient's overall health and well-being. He collaborated with a broad network of natural practitioners, chiropractors, acupuncturists, physicians, and specialists in muscle testing, nutrition, homeopathy, aromatherapy, detoxification, and other complementary health disciplines. His practice became known for combining high-quality dental care with a whole-body approach to health.

Located in Weyauwega, Wisconsin, Dr. Twohig's practice was built on the philosophy that dental treatment should support—not compromise—the health of the entire body. He continually pursued advanced education through seminars, professional organizations, and continuing education courses, thoughtfully integrating evidence-based innovations and emerging technologies into his practice.

For more than 30 years, Dr. Twohig was deeply committed to advancing the understanding of biological terrain and its impact on oral and systemic health. He completed extensive training through the International Academy of Oral Medicine and Toxicology (IAOMT) and incorporated its principles into his approach to patient care. Inspired by pioneers including Dr. Phil Mollica, Dr. Robert Harris, and Dr. Julian Holmes, he became an early advocate for ozone therapy in dentistry. His use of ozonated air, water, and oils helped provide therapeutic and preventive benefits while minimizing reliance on harsh chemicals.

Dr. Twohig became widely recognized as a leader and lecturer on ozone therapy and was a founding member of the American Academy of Ozonotherapy (AAOT), helping educate both dental professionals and healthcare practitioners on the benefits of integrative treatment approaches.

Throughout his career, Dr. Twohig believed that patients should be active participants in their own healthcare. As awareness of holistic wellness continued to grow, he remained committed to educating patients and mentoring fellow practitioners who sought to expand their understanding of biological and integrative dentistry.

Although now retired, Dr. Twohig's impact continues through the countless patients he served, the practitioners he mentored, and the innovative philosophy of care he championed over five decades.
