About us..... introducing the staff of Hayes Endocrine and Diabetes Center!
Dr. Hayes is very proud of her professional, hard-working staff.  The team at HEDC really enjoys working together and considers each other more like family than co-workers.  We often hang out together after hours! We are highly committed to our jobs and we even have some fun along the way!
Kay Williams, APRN/BC
Our beloved Kay, our Nurse Pracititoner of 13 years has certainly won the award for diligence and longevity at HEDC.  She joined Dr. Hayes in 2004 and has accumulated quite a following of patients who love and adore her.

Kay has devoted her career to the nursing field.  As an RN she spent 18 years in office practice of obstetrics/gynecology and dermatology.  She attended Belmont University for both her RN and BSN degrees.   Kay's husband Ralph, pharmacist and owner of Healthmart Pharmacy in Hendersonville, developed Type 1 diabetes during his 4th decade.  They as a team have coached and helped hundreds of patients with diabetes over the years.

Kay's favorite pass time is spending time with her two young grandchildren Mattie and Jack.  Shockingly, just a year or so ago, Jack was diagnosed with Type 1 diabetes at the tender age of 4. As one might expect, Jack and Ralph both do exceedingly well with their blood sugar control and although the two are generations apart, their common thread is a great attitude and respect for the disease that each must call his own.

 To say that Kay lives and breathes diabetes is an understatement.  She diligently gives her time, attention and expertise to her patients all day and gives more of the same to her family!  Kay captivated Dr. Hayes with her beautiful smile 13 years ago and she has been nothing but a blessing to work with all these years.  Dr. Hayes and her patients are never going to let Kay truly retire!
