Meet Our Doctors

Jonathan Chang, DMD

Dr. Jonathan Chang grew up in Alhambra, California. He is a general dentist who has a passion for restorative and cosmetic dentistry and prides himself on making his patients feel comfortable in the chair and confident about their smile. By listening to his patients’ needs and emphasizing the importance of a good home care regimen, Dr. Chang believes he can create a meaningful relationship with every patient and ultimately help them achieve their desired level of oral health.

Dr. Chang received his Doctor of Dental Medicine degree from the Medical College of Georgia in Augusta. He was most recently a clinical director for a dental service organization in the Greater Atlanta area and has also been involved in dental mission work, which he has found to be very rewarding.

Both University of Georgia alumni, Dr. Chang and his wife, Kristin, make their home in Sugar Hill. They are the proud parents of a Beagle, a Yorkie, and a Chihuahua mix. Dr. Chang is an avid basketball fan and enjoys playing tennis and swimming in his spare time.

Ruby Truong, DMD

Dr. Ruby Truong is originally from California but moved to Georgia with her family at a young age. She studied dentistry at the Medical College of Georgia in Augusta, Georgia where she received her Doctor of Dental Medicine degree. Her favorite part about being a general and family dentist is seeing the impact on people’s lives that dentistry can provide. She enjoys helping patients, whether it’s getting them out of pain, restoring their smiles, or simply helping them improve their overall oral health.

Dr. Truong believes the path to good oral health begins with the doctor-patient relationship. By forming a partnership with her patients, educating them about the importance of proper home care and learning to understand their goals and desires, she believes she can help guide them toward achieving their desired level of oral health. Dr. Truong enjoys and is committed to continuing education courses to keep her up to date on new research, technology, and other advancements in dentistry so she can continue to provide high-quality dentistry for her patients.

In her spare time, Dr. Truong enjoys spending time with friends and family, going to the gym, and trying new things.

Meet Our Team

Kristin

Office Manager

Kristin is Sweet City Smiles’ office manager and yes, Dr. Chang’s wife! After listening to Dr. Chang talk about teeth for their entire relationship, she decided to join in the fun and put her office management experience to use at Sweet City Smiles. Her favorite part of being an office manager is building relationships with patients. She believes that serving and supporting others is her greatest purpose, and strives to make every patient feel welcome, supported, and respected.

Kristin grew up in Lawrenceville, Georgia by way of Louisiana, New Hampshire, and Colorado. She has two degrees from the University of Georgia and a graduate certificate from Georgia State University. Fun fact: Kristin and Dr. Chang went to the same high school and the same college but never met until after they both graduated! In her spare time, Kristin enjoys reading, volunteering, and moonlighting as a Disney travel agent.

Judy

Dental Assistant

Judy is Sweet City Smiles’ dental assistant and has been with our team from the very beginning! She was born and raised in Bogota, Colombia, and now lives in Sugar Hill with her two wonderful children Julie and Leandro. She is very outgoing and always carries a smile on her face. She enjoys working out in her free time and loves cheering on her two kids in everything they do.

Judy’s interest in dentistry came from her sister, who is also a dental assistant. She loves caring for patients and has also been a tremendous help as a Spanish interpreter when the need arises. Plus, she’s helping the team improve their “Español” as well! Judy’s connection with our patients and her incredible work ethic make her a tremendous asset to our team.

Danielle

Dental Assistant

Danielle is Sweet City Smiles’ dental assistant and was originally a patient of ours! She loved her experience so much she decided to ask if we had any plans in growing our team, and the rest is history!

Despite being new to dentistry, her favorite part is already the fast-paced environment in which she gets to learn something new every day. She also enjoys building a unique and genuine relationship with each of her patients. Danielle has been such a great fit for our team because of her friendliness and her desire to make every patient feel the way she did when she first came to see us.

Before moving to Sugar Hill in 2019, Danielle grew up in South Florida and spent time studying Psychology in New York City. She loves spending her free time with her family, specifically traveling and boating!

Julie

Patient Coordinator

Julie is Sweet City Smiles’ patient coordinator! She was born and raised in Georgia and is always up for a challenge. She recently graduated from Georgia State University, and was pleasantly surprised that she would end up working at a family dental practice. Fun fact, Julie is actually the daughter of one of our dental assistants, Judy! After hearing her mom talk about her experience with our team, Julie decided it would be a great opportunity to hop on board and pitch in as much as she can. Her favorite part is being able to talk with patients and get to know them, because she wants every patient to feel comfortable and enjoy their experience here.

During her free time, Julie enjoys binge watching Netflix, but also loves to stay active. After a busy day at the office, you will still see Julie at the gym lifting weights and making sure she gets those steps in!
