Our Staff

Alexa - Dental Hygienist

I was born and raised in Snellville. I live there with my husband Matt and my daughter Isabella. We love being outdoors and active as much as possible and spending time with family. I love my job as a dental hygienist and taking care of people every day. It has been so great to work with everyone at Gangwisch Dental Group!

Amanda - Office Manager

I'm a Georgia native currently in Gwinnett County. In my free time I enjoy spending time with my husband taking road trips, the best ones don't have a plan so we can enjoy the journey. I've enjoyed a 20 year career in the dental field that has led me to Killian Hill. I'm looking forward to being here for a long time, the team here is incredible and so are our patients!

Autumn - Dental Hygienist

I grew up in Covington. I've been working at Killian Hill Dental Care since June of 2022. I graduated with my bachelors in dental hygiene from Augusta University. I enjoy traveling, spending time with my family and friends, and loving on my Husky-Shepard mix. I'm glad to be a member of the Killian Hill family!

Blanca - Business Assistant

I was born in New Jersey but I was raised in GA - a true Georgia girl. I have a beautiful daughter Abby who is my best friend. I enjoy cooking, especially for others. I love traveling; the beach is my oasis. I have been a part of the Killian Hill Dental Care family since 2015. I enjoy working with wonderful, fun co-workers and patients. I could definitely call Killian Hill Dental Care my second home.

Courtney - Dental Hygienist

I live in Dunwoody with my husband Brandon and our dog Murphy. I have been working for Dr. Gangwisch since 1996 and I have really enjoyed it. I can’t imagine working anywhere else. I graduated from Georgia Perimeter College with a Hygiene degree in 1996. I am really family oriented and love to spend time with my friends.

Kelsey - Head Dental Assistant

I live in Lawrenceville with my husband Tim. We have three sons, Parker (born in 1997), Jack (born in 2000), and Aaron (born in 2004). I enjoy reading and you can always find me at the park watching my sons play baseball. I've enjoyed working here since April 1993.

Kim - Business Assistant

I was born in Miami, but my parents moved to Norcross (Go Blue Devils) when I was 10. So I consider myself a Georgia girl. The beach is definitely my favorite along with all of my fur babies. Animals are, for sure, my passion. I am so blessed to be a part of the Killian Hill Dental team.

Macy - Dental Assistant

My name is Macy and I have been a part of the Killian Hill Dental care family for years as a patient. In 2019 I became part of the work family. My fiance, Jared, and I have a son named Stone who was born in 2018. We also have two fur babies (dogs) named Chief and Kia. My love for dentistry was brought out to me by my aunt who has worked with Killian Hill for almost 30 years. I am very proud to work with doctors who deeply care for our patients and their health rather than the financials. I trust in my doctors and our team with my family and friends for their dental care needs. Killian Hill Dental Care is definitely my home away from home. My biggest daily goal is to see you and your families come in and leave with a big smile on your faces.

Rahel - Dental Hygienist

I was born and raised in Addis Ababa, Ethiopia. I currently reside in Snellville, GA with my husband and have 3 beautiful children. I have been a hygienist since 2011 and part of Killian Hill Dental Care since 2019. I like to spend my spare time with my wonderful family and I love cooking, listening music and taking vacation (traveling). I love being a hygienist because I enjoy educating patient about their oral health and giving them quality of care.

Roxann - Dental Assistant

I’ve been working at Killian Hill Dental Care since November 2007. I have four amazing children, Ashley (born 1986), Andrew (born 1988), Sean (born 1992), and Jessi (born 2002). I enjoy spending time with my children and all of their activities. Working here is a pleasure; the staff and the patients are wonderful.

Violet - Business Manager

I live in Snellville with my wonderful husband Ken. We have three children, Jennifer (born in 1982), Melissa (born in 1984) and Kenny (born in 1988). I was born in Santiago, Chile. I lived in Connecticut for 29 years before moving to Georgia in 1991. I speak Spanish fluently; love to watch football, Georgia Bulldogs and New York Giants are my favorite. In my spare time I enjoy cross-stitching, decorating, skiing and being a mom! I've been fortunate to work here since May 2000.
