Our Staff

Tabitha - RDH, BS

Billing Specialist

My name is Tabitha and I am the Registered Dental Hygienist at Sienna Pediatric Dentistry. I graduated from Jackson State University with a Bachelor of Science degree in Biology and then graduated from the University of TN Health Science Center with a Bachelor of Science in Dental Hygiene. I have been a practicing registered dental hygienist for 6 years and enjoy working with children. I love the ability to give my patients and their parents a pleasant experience while providing them with the best preventive dental care and knowledge.
In my spare time I enjoy traveling, shopping and spending time with my husband David and dog Zoey.

Samecia – Practice Manager

Billing Specialist

My name is Samecia and I am the practice manager at Sienna Pediatric Dentistry. I am new to the pediatric dental field and have enjoyed every minute of it. Dr. Howe and staff strive to create a great experience from sign in to checking out which makes for a great environment. I am currently in school majoring in Biology to eventually become a Dental Hygienist.
In my free time I am studying, spending time with my family or skimming through Pinterest for another craft to tackle.

Elizabeth - RDA

Billing Specialist

My name is Elizabeth, and I have 15 years of dental experience and 8 years working for Dr. Howe as a Dental Assistant. My experience at Sienna Pediatric Dentistry has given me the ability to grow professionally in every way. I truly enjoy the interaction with kids and parents and then receiving that big smile at the end as positive feedback always gives me pride in my work.
When I leave work I go home to my husband Melvin and our fun loving dog named Romeo. I thank you for trusting us with your child’s dental needs and look forward to serving you.
