Nannette L. Wortham, B.S., COHCMs. Wortham - Professional Audiological Services


Ms. Wortham has over 10 years of professional experience with Professional Audiological Services.  She has a lifetime of experience in dealing with hearing loss since both she and her twin sister were born with bilateral hearing loss.  She was first introduced to Professional Audiological Services as a child where she was fit with hearing aids.

Her love for animals resulted in a Bachelor’s of Science Degree in Animal Science (2000) from the University of Tennessee at Martin. However, her personal experience with hearing loss and her strong desire to help others drew her to the field of audiology. She has played a major role in the growth of PAS, Inc.  Her expert skills and abilities in technology, management and patient care are a significant asset.  In addition, she is also the Clinic Director for PAS.

Ms. Wortham has refused to allow hearing loss to hinder her love of life. She enjoys barrel racing her three horses and is a member of the National Barrel Horse Association. She has also qualified for the World Championships for the NBHA at least four times.  She is a dedicated member of her church where she participates in musical/drama events and sings in the choir.Nannette
