Dr Macklin is the gold standard all doctors should strive to be! I’ve been her patient for many years now and she still spends quality time at every appointment and listens to all my concerns. Best primary care physician I have ever had! Also, all of the staff at Family Practice center are top notch. Always friendly and eager to help!

Marvin Brannon

We are very happy to have found such a wonderful new family practice after moving to the Atlanta area. Everyone was extremely professional and friendly from the moment we arrived to when we left. Most importantly, the care my daughter received was excellent and very thorough!

Sharon Williams

Kelly Pierannunzi is the best family medical doctor I have ever had. I rarely seak medical treatment but wanted a family doctor for physicals and unexpected illnesses if they happen. Kelly takes her time to get to know you as her patient, understanding your family history and who you are so she can provide the best treatment and guidance possible.

Dr. Niazy was amazing! I’m so happy I found her, she made me comfortable. Listened to my needs & was so filled with joy it was contagious. I would recommend this office, the staff was great as well.

It is rare to find a doctor who truly hears and sees you as a person, but Dr. Tyler Wheeler does exactly that. He is incredibly compassionate and never dismissive of my concerns regarding my own health and body. As a former caregiver, I’ve seen many specialists who treat patients as ‘inferior,’ but Dr. Wheeler’s bedside manner is unmatched. I finally feel like I have a partner in my healthcare.

Dr. Macklin and her staff are always amazing!!! Her approach and bedside manner is patient and kind. You don’t find a lot of doctors who care about their patients wellbeing any more! By far, she is the best doctor at this practice in my opinion and this coming from a patient who has been seeing her for five years!

I have been a patient of Dr. Smita Kapoor at Family Practice Center in Johns Creek since last year, and she is an exceptional doctor as well as a wonderful human being. I moved to GA five years ago and only last year was I able to find an excellent primary care physician. I’m very grateful to have found her.”

Carola Molina

Dr. Joseph is beyond a patient’s PCP, she is a trusted health partner and advocate. I am grateful to have a physician who combines clinical excellence with warmth and humanity. Highly recommend!! P.S. The Sandy Spring and Smyrna office staff are both exceptional and always professional!

Dr. Adrianne Redmond

Today was my first visit here. I was seen by Dr. Macklan. She did an excellent job. Listens to everything you have to say with an open mind. She shows genuine concern for a patient’s overall well-being. I’m glad I made the decision to go here.

Michael Sample

I highly recommend Family Practice Center in Braselton. I needed a new PCP and took a chance on Kelly Pierannunzi, MSN FNP-C, and am so glad I did. Kelly is a true delight and has been wonderful—she is very knowledgeable, takes the time to listen, works with you on your health issues and genuinely cares about you.

Christine Knight

Dr. Wheeler is always on time and very efficient. He takes the time to answer my questions and clearly explains treat plans and options for me. The entire staff is dedicated to the care of their patients.

Frequently Asked Questions About Your Care

It can be helpful to write down your main questions ahead of time and bring any medications, updates, or records you would like to discuss during your visit.

Primary care visits are a good time to review recommended screenings, routine health needs, and other steps that support long-term wellness.

In many cases, patients can discuss more than one issue during the same appointment, depending on the visit type and time available.

Primary care plays an important role in tracking changes in your health, adjusting treatment when needed, and helping you plan next steps with confidence.
