Erin and the entire staff in Evolution are amazing people. I decided to contact them because I was at the end of my rope trying to figure out how to fix my health. Nothing I did was working. I honestly had reservations about this program too. I was so wrong! The diet, supplements, and meds they gave me absolutely were worth it all. They were able to figure out what was wrong and gave me everything I needed to help my body "reset." The program and instructions were easy to follow, I always got responses when I had questions, and they made it so easy to get refills for whatever I needed. My health is improving drastically and my weight is coming off like it's supposed to. I'm so much happier now and I highly recommend this place to anyone who's regular doctor just seems to be treating symptoms and not the problem.

I came to Evolution in hopes of relief of daily migraines, and I found it! Erin and her team identified the issue instead of just treating the symptoms, so I'm forever grateful!

Do this for your health! If you're tired of "sick care" and want to truly improve your health, this is the place. Erin helped me get my labs back to normal, get off other medications, and focus on holistic health improvement.

Evolution saved my daughter. With a POTS diagnosis she was given multiple medications and felt terrible… even worse. Erin Bolton got to the root of my daughters health issues so efficiently and quickly my daughter felt better one day later and has improved , gotten stronger and able to eat and be healthy! Money we’ll spent! Amazing

I cannot thank God enough for helping me find Erin and her staff at Evolution Weight Loss and Hormones when I needed them the most. I have been through a long journey of medical conditions and unexplainable symptoms for more than twenty years. I have seen many doctors, and none of these doctors have been able to help me with my symptoms or giving me a specific diagnosis. The worst and most terrifying part of this ongoing journey was to see how my doctors continued to prescribe medications that could cause severe side effects without having a proper diagnosis. I came to Erin with a long list of unexplainable and chronic issues starting with my stomach, joints, skin, inflammation, arthritis, pcos, insomnia, hair loss, I could not drink water because it will upset my stomach so bad, and the list goes on and on. I was exhausted and felt helpless. However, I continued to pray for answers. Since my conditions have been going on for many years and have become chronic, it took Erin long hours to analyze my symptoms, review all my test results, order new lab work and review my medical records in order to give me some answers and point me in the right direction to heal. I can now say, my overall health has improved tremendously. The process has taken time and requires patience, hard work, commitment, and communication. I can now drink water and my stomach can tolerate it!! I thank God for listening to my prayers, and Erin for not giving up on me. Erin’s dedication, passion and willingness to help so many people in need of answers to their rare and chronic medical symptoms is truly admirable and next level. She will always do right by you, she is understanding, receptive, fair and will treat you like you are part of her own family. Her staff is so nice, supportive and always available to help in every way they can. I cannot thank Erin and her staff enough for helping me improve my health and quality of life, for helping me find some long awaited answers, and for pointing me in the right direction to continue to heal. Please if you are suffering from unexplainable symptoms and have been diagnosed with multiple medical conditions without getting the root cause of the symptoms, you must give Erin and her wonderful staff a try, you will not be disappointed!!

Erin and her team, especially Kaley, are absolutely wonderful. They are professional and take all questions, concerns and calls, seriously. They strive to give the client the best possible experience, which is why I continue to see them for my particular need. Communication is the key and Erin takes pride in providing excellent communication between her clients and vendors. I HIGHLY recommend giving Evolution a try for yourself to experience one of the few places that offer quality and care, concerning the client’s experience and overall ease with dealing in healthcare.

We are eternally grateful for the transformative experience we had at Evolution. Seeking medical care for Wilson's decease, we were on the verge of losing hope until we found Erin and Evolution. From the start, their compassion, expertise, and dedication to healing shone through. Erin took the time to listen (and still does it every time), conducted a thorough examination, and created a personalized treatment plan. Their holistic approach combined evidence-based treatments, personalized nutrition plans, and cutting-edge therapies. The care I received not only effectively managed Wilson's decease but also sparked significant improvements in my well-being, giving our whole family a renewed sense of hope and joy. We wholeheartedly recommend Erin and Evolution for life-changing medical care.

My body was telling me there was something wrong and after my very first visit with Erin, I knew that I had found the answer to my prayers! She was true to her word and within months she had me turning a major corner! I can honestly say, I have never felt better! The entire team is amazing, friendly, patient and professional!

Dr Scott Coletti Chiropractor & Functional Medicine support

Dr Scott Coletti DC


Dr Scott Coletti, DC

A Firsthand Experience with Chiropractic

All of the kids on the baseball team, including Dr. Scott Coletti got adjusted and looked up to the chiropractor. This experience gave him a firm foundation of chiropractic care and intrigued him to learn more.

Growing up with a mentality of healing naturally, Dr. Coletti rarely took medications. He believed that when it came to health, less was more. This philosophy aligned with chiropractic care as a means of natural healing without the use of drugs or surgery.

Once he graduated with his undergraduate degree, he called a friend who was a few years older that was in chiropractic college. After talking to him, he gravitated toward chiropractic college and hasn’t looked back since.

Becoming a Believer

Dr. Coletti chose to attend Life University in Marietta, GA. He still remembers a time during his residency in Marietta when he was delivering newspapers early in the morning. One customer had a 9 year old daughter who wasn’t able to control her bladder, had to wear diapers and had been to every physician or specialist they could think of.

Dr. Coletti recommended that she and her daughter visit him for care. They arrived, desperate for anything to help. After just three adjustments, he was able to align the girl’s spine and lower back that helped her regain control of her nerves.
