What Makes Us Different?

Functional medicine is growing because it gets results. Our treatment is a four pronged approach.

  • First of all we have a one on one consultation to discuss and identify your issues and your needs.
  • Then we request extensive bloodwork to fully understand what deficiencies (or too much of) you have in your body.
  • We then have a follow up consultation to discuss a plan of action and supplements you will take to get back to proper being.
  • Finally we move onto a manage and maintain process to help you stay fit and healthy.

Our approach is tailor made to your own specific needs and designed to put your body back in balance, back to how it is supposed to be.

What is functional medicine exactly?

Functional medicine is an approach to healthcare that focuses on treating the root causes of health issues, rather than just addressing symptoms. It takes into account the unique aspects of each individual’s body and their environment to create a personalized treatment plan.

Functional medicine practitioners aim to understand how different systems in the body are interconnected and how imbalances in one area can affect overall health.

This approach often involves looking at factors such as genetics, lifestyle, diet, stress, and environmental influences to promote optimal well-being. In essence, functional medicine seeks to promote health by addressing the underlying imbalances that contribute to illness.

Why do you think you will be able to treat me when other doctors say they cannot?

Functional medicine seeks to identify and address the root causes of health issues, rather than just alleviating symptoms. By targeting underlying factors, it’s believed that the body’s natural healing mechanisms can be better engaged and generate results that traditional medicine may not have.

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.

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.

Top notch team that goes above and beyond to truly HELP clients Iive their best lives! I was so tired of hearing from my primary care physician that all my tests came back normal and there really wasn't anything wrong! 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! I can't say enough about Evolution Weight Loss and Hormones!!!

I am not one to write reviews, good or bad… but I had to share…  I am beyond grateful for the compassionate care provided by Erin and her team… Throughout my health journey, their kindness and dedication have made a world of difference… From the very beginning I felt at ease… My journey has been long, and it wasn’t until I found Evolution did, I finally find a solution…

Erin is not only an expert in her field but also takes the time to explain things thoroughly… It’s rare to find a doctor who combines expertise with genuine care for their patients and she does just that… Every appointment feels like a conversation with a friend who genuinely cares about my well-being and getting to the root of my issues…

As well as I cannot say enough of the entire staff – no matter how big or small, an email or phone call… every question or concern has been answered efficiently with understanding, kindness and quickly!

Thank you, Erin and your entire team for your healing and compassion… I truly believe I would not have survived this journey if it were not for you!  May you continue to touch lives and make a positive impact… God bless you!

Thank you!
