Testimonials

  • When I first went to Megan, I was tired, bleeding all the time, and struggling with my weight. Megan has helped me to find a vitality I hadn’t felt in years, and has normalized–or even optimized–my hormones. Megan and her team engage in continuous training to keep up on the latest medical breakthroughs. I trust Megan with my healthcare, and I highly recommend Fit Logic Functional Medicine to anyone who is tired of feeling tired.

  • Highly recommend!!! I started my journey with Megan and Cecili in late March. I have never felt heard before with my health concerns.They LISTEN! I feel cared for and heard. If you are struggling with why you can’t lose weight or why you’re loosing your hair, always tired…I can go on. We need to help each other out by talking about this! Thank you Fit Logic!! I feel amazing already and We just got started.

  • I started my hormone and thyroid and gut health journey with Fit Logic over a year ago. My first appointments were with Megan and Cecili and what I can say about them is that they truly listen and care. It’s rare to find medical professionals that really want to hear everything so they can best understand what you need and how they can help you. They are knowledgeable, encouraging, and gifted at what they do. After a year, and a lot of tweaking my treatment as we went, all of my levels have improved! They really care about how you feel and how they can help you feel better. My hormone and thyroid journey has been a long one and I finally found the right team of people! I cannot say enough great things about them or recommend them enough!

  • I began seeing Megan not quite 1 year ago for hormonal & thyroid issues. On the day I was to have my second appointment with her to go over results of lab work and go over a plan for me I received the news that I had been diagnosed with breast cancer. I decided to go to my appointment with Megan anyway and I am so glad I did! Even though I barely knew her I felt she was there for me. She came up with a plan for me and included supplements to help me while receiving chemotherapy. I feel her plan helped me get through all of it with much more ease than it would have been without. She (and her staff) are very caring and make a person feel very welcome. She is also very attentive and asks about every aspect of your life to try to help a person to heal and feel their best. I will continue to see her as I believe she is very knowledgeable and can help me to continue healing and become healthier. I am so thankful for her help. I would recommend Fit Logic to all my friends.

  • Fit Logic was recommended to me by a friend. Best choice I have made in years. Dealing with fatigue, loss of drive & libido, trouble losing weight, name it. I chalked it up to age. Well, yes, but so much more. Now I’ve enjoyed a reversal of all of those things and feel like I’m living again! Megan, Cecili and the crew are great and have made a true positive impact in my life. Cannot say enough good things about them!

    Jerry
  • I cannot say enough positive things about Megan Miller and Fit Logic Function Medicine. I have a few autoimmune issues and over the last 15 years have seen multiple doctors and specialists. By coincidence/chance, I met Megan and scheduled my consultation. I immediately knew her approach was different than other providers I had seen and knew it was exactly what I was looking for. The amount of time Megan took with me to listen and understand my health history was something I had never experienced before. For once I feel heard and understood! For the first time in years, I wake up with energy and get a restful night’s sleep. The symptoms of autoimmune issues are lessening every day. I feel very grateful to have met Megan and to have her in my corner through my health journey!!

    Camilla
  • I’m so grateful for Megan, April and Cecili! They have provided me exceptional healthcare and support. I am becoming a different, healthier, happier woman because of their support of my hormones and gut. I’m losing weight and feeling AMAZING! I highly recommend Fit Logic and Megan Miller’s awesome team to all my friends.

  • Megan Miller changed my life. When I first went to her I was sluggish, unmotivated, cranky and everything felt like a chore. She really took her time with me and we talked about all the things that were currently going on. Megan was able to identify supplements that I could start right away and ordered a thorough blood panel. When the results came back, Megan spent time explaining the results and answering all my questions. She gave me recommendations and options and helped me decide the best solutions for me. It has been about 6 months and I really am a new woman. My motivation is back, my mood is elevated and I feel great! I have recommended her to all the women in my life.

    Medea
  • Before working with Megan Miller I was overweight, lethargic, depressed, and sick for years. I had gone to countless doctors and was given numerous medications that did not work and nothing ever seemed to address the “root” issue. Fast forward just four short months under Megan’s care and my life has completely changed. I have much more energy, I’ve started losing weight (I fit into my old High School cheer leading uniform!), my anxiety has improved and my depression is completely gone. My relationship with my husband has benefited as well! Thanks to Megan, I feel like I have my life back!

    Jaime
  • I have been to so many doctors, have had so many tests done, and been told over and over that everything is “normal.” Turns out, it wasn’t. It wasn’t until I turned to functional medicine practitioners that I got real answers and noticeable changes. In just 2 months of working with Megan, I feel better than I have in 20 years. She told me that she wouldn’t stop until we figured out what was happening. Megan asked questions and made connections that I never would have thought would connect back to my long term health. Before meeting with Megan, I had given up and just accepted that this was going to be life (especially life after cancer) but she has shown me that I absolutely do not have to live with pain, discomfort, and imbalance. I can’t wait to see how I will feel in a few more months!

    Esther
  • After being told all my labs were “normal” by my OB/GYN but feeling frustrated because I just didn’t feel good…like ever…and my cycles began ruling over half of the month I am so glad I saw Megan! I was feeling terrible and having mood swings for half of the month. She took a deeper look into my labs and has me on a regimen of supplements and it has changed my life! I feel more energized and hardly ever have mood swings - even my hubby noticed!! We’re there some lifestyle changes I had to make…yes, but it was simple and it’s totally worth the shift. I’m so grateful for how much better I feel now and also that I’m on track to aging gracefully and potentially preventing disease.
