Cassandra Hayes-Branch

She is a native Nashvillian and continues to reside there.  Due to her passion for Healthcare and overall physical fitness, she obtained an Associate Degree in Nursing from the University of Tennessee at Nashville.  She began her nursing career providing hands-on care in hospitals.  She recognized that although hands-on care was essential, it was just as essential to teach others how to manage their disease states, and decrease their risk factors which improve their overall health, which decreases the risk of developing more chronic medical conditions as well.

She also recognized a need for additional personal and professional growth.  She obtained her Bachelor of Science Degree in Management and Human Relations at Trevecca Nazarene University in Nashville. She has more than 30 years’ experience as a Registered Nurse.  Besides hospital experience, she has worked in the Home Health industry and has experience in Case Management. 

Teaching and educating is her biggest strength. She also has worked in Bio-Technology as a Clinical Specialist. In this position, she educated Physicians, Mid-level Providers, and Nurses on cutting edge pharmaceuticals.  She was part of the HindSight Services Inc initial launch and rejoined Hindsight Services in 2017, which has allowed her to continue to educate and teach on a bigger platform reaching many others.  Education on Smoking Cessation and Stress Manager is key to decreasing risk factors for many disease states.
