GTC Certification

Geriatric Rehabilitation Education and Training Institute


Certification is designed to offer a series of courses, which culminate in a comprehensive examination consisting of written, oral and practical testing to define competency in geriatric rehabilitation.Certification is a four-day process, consisting of a review, and collegial exchange which provides the opportunity for both reviewing and updating the contents of the courses leading to certification. The third day, the written exam is taken followed by the oral exam. The last day is the practical examination with real patients to complete the process. The standard sought is one of excellence, safe application of advanced clinical skills and culmination of all pertinent information and the ability to analyze and plan in the most current and critical fashion to advance healthcare for the geriatric population.The Geriatric Training Certification is usually held in January of odd years. Please contact the GREAT Seminars office at 877 794 7328 to inquire about the actual GTC dates. Once a potential applicant has completed at least 5 of the required 8 GREAT Seminars & Books courses, you should contact us regarding your intent to participate in the GTC and for further instructions. We will need your name and a list of courses you have taken at least 6 months prior to the scheduled dates of the GTC.

The Howard Pai Award

The Howard Pai Award was created to honor Howard Chia-Ho Pai, an extraordinary physical therapist. It is bestowed on a therapist sitting for the Geriatric Training Certificate (GTC). The funds are raised by donations from Great Seminars and Books seminar participants and matched by Dr. Lewis, so the amount varies from year to year. The honor is conferred on the GTC who has gone above and beyond, as Howard did in his lifetime. It is determined by the faculty at the GTC training and announced at the concluding celebration.

Howard Pai received his GTC in 2005.  At the ceremony, he made a short speech, during which he proclaimed that earning a GTC was one of his life’s great achievements.  He had prepared and studied for months.  He was the oldest GTC to sit for the certification process and even though he felt at his age it was tough and tiring, it was worth it.  He was beloved by his fellow classmates and all the instructors for his willingness to strive for excellence, his tenacity and his kindness.

Howard worked full time as a physical therapist while earning his GTC and for many years after.  One of his patient’s wrote “…I lost a good friend…He helped me so much with my husband…He was better than family…Can you imagine him coming once a week to check on my husband…Even families don’t do that.” Howard went out of his way to help almost everyone he met both in his classes and in his community He was tireless in his efforts to serve geriatric patients.

Several years ago Howard was diagnosed with Amyotrophic Lateral Sclerosis (Lou Gehrig’s Disease).  He died November 7, 2011 at the age of 67.

The Certification

In 1992, Dr. Lewis founded the Geriatric Rehabilitation Education and Training Institute in an attempt to standardize and improve the quality of continuing education available to all rehabilitation professionals. An eclectic approach to all types of geriatric patients and diagnoses has been created through a series of courses, which allows the GREAT Institute to offer a Geriatric Training Certification (GTC). The Certification is designed for practicing physical and occupational therapists and assistants. GREAT Institute will honor all course work in which a GREAT Seminars and Books, Inc. certificate was awarded. Due to the dynamic nature of health care, the courses are constantly being updated. Courses taken prior to 2000 will not be considered for credit.
