Dear North Raleigh Pediatric Group Families,

After 35 years of practicing pediatric medicine at North Raleigh Pediatric Group, I am announcing my immediate retirement.  Thank you for entrusting me with your children’s medical care through these years.

Elizabeth Rattle, PA, the management, and staff are here to serve you. We are in the process of hiring another physician to take my place. Your medical records will be available if requested, although I encourage you to continue to receive the high-quality medical care that North Raleigh Pediatric Group has always and will continue to provide you.

It has been my extreme privilege and a pleasure to care for each of you, and I thank you for allowing me to be a part of your lives and to watch your children grow and learn. My practice has been a great joy in my life.

I wish you all heath and peace in years to come!
