Meet Our Team
Mary, Office Manager
“I was born in California and now live in Winder, Ga. I am married to Jay, and we have two children, Keenan and Jaslyn. I have been in dentistry since 2007. Throughout the years I have worked as a dental assistant and front office gaining knowledge of many areas of the practice. For the past couple of years as a treatment coordinator, I have had the pleasure of being able to work with patients by helping them obtain the best benefits from their insurance company. My job is enjoyable because of the friendships that I have formed throughout the many years and I look forward to making new friends for the many years to come.”
Kristen, Front Office Administrator
“I have been a patient of Dr. Lewis Petree for over 30 years, but now have the wonderful opportunity to work alongside him. I was born and raised here, in Winder. I married my best friend from high school, and we've been blessed with three amazing children. I enjoy anything outdoors, playing and coaching volleyball, running, as well as volunteering within the community.
Though my experience has been primarily in specialty offices, the knowledge and relationships I have built provides me with the ability to better serve the office. I enjoy working hand in hand with the doctors and patients to ensure you get the exact quality of care you need.”
Kacie, Dental Receptionist
“I was raised in a small town just outside of Macon, Georgia where my upbringing centered on family, community, and time spent on the ball field. In 2016, I moved to the metro Atlanta area with my husband, where we have since purchased a home and started a family. We are proud parents to our daughter, Evelyn, who was named in honor of both grandmothers. In our spare time you will find us cheering on both the UGA Dawgs and LSU Tigers. In 2025, it was a pleasure to join the dental team of Petree & Seibert Family Dentistry, and to serve our patients, families and friends.”
Maria, Registered Dental Hygienist
“I was born and raised here in Barrow County, and have worked in dentistry in Winder for 42 years as a dental hygienist. Dentistry has always been a part of my life beginning with my dad, the late Dr. Dick Golden and later with my brother Dr. Richard Golden, who’s now retired. I enjoy building relationships with my patients, and especially love seeing multiple generations of families over the years. It means a lot to be part of their care and to watch them grow.”
Christina, Registered Dental Hygienist
“I've been part of the Petree & Seibert dental team since 2002. In 1999 I graduated from Gainesville College and Lanier Technical College with an Associate degree in Applied Science and a Dental Hygiene Degree. Prior to becoming a hygienist I worked as a dental assistant, which further inspired my love of dentistry and taking care of patients. I am married to Greg Gustus. We do not have children, however, we do have precious fur babies. The two cats and a Chihuahua are rescues, and I also love horses.”
Kim, Registered Dental Hygienist
“I have been in dentistry since 1989 when I started my career as a dental assistant. I graduated from Gainesville State (now a part of the University of North Georgia) and Lanier Tech with an Associates in Applied Science and Dental Hygiene Degree in 1995. For the last 34 years, I have been in a practice in Buford, Georgia. I am excited about my new relationships with patients here and working with my new team at Petree & Seibert Family Dentistry.
When I'm not working, I enjoy spending time with my family and friends. I am married with two girls and have four grandchildren. Also, I enjoy camping, boating, and being outdoors.
I look forward to educating our patients and building relationships, and I look forward to giving the same quality care here that I've been offering for the past 34 years.”
Giselle ‘GG’, Dental Assistant
“I was born in Mexico City, but grew up in Chamblee, GA. In 2018, I moved to Winder and in 2019 I attended Alterius Career College for their dental assisting program. I enjoy what I do as a dental assistant; being able to help guide our patients through their treatment from start to finish. Seeing their end result with all smiles is simply gratifying.
During my free time, I like to spend it with my family, boyfriend and most of all my two year old daughter, Alana. I look forward to making all patient's experience here to be the most comfortable and easy time here with us.”
Grace, Dental Assistant
“I started working as a dental assistant in 2018, and had the pleasure of joining SP Family Dentistry in 2023. Dentistry has given me the opportunity to work with different people and to help with creating new and healthy smiles. On my off days, I spend time with my older sister, nephew and my dog, Penny.
I enjoy sharing my favorite activities with my family and friends, such as trying new restaurants, biking, video games, going to the movies, and just spending time with those I care for.
My hobbies include, reading, writing, and music. My goals are to do what I love, spend time with my family/friends, and to always treat people with sincerity.”
Linsee, Dental Assistant
“I'm a native of Barrow County and have been a dedicated dental assistant since 2018. I was excited to join the Petree & Seibert Family Dentistry team in 2024. I'm very passionate about delivering exceptional patient care and intentional about creating a comfortable environment for patients daily. When I'm not working, I cherish spending time with my husband and our dog, while also making every effort to prioritize quality time with friends and family.”
