“I can’t say enough positive comments about Diane. She is a wonderful and thorough practitioner! She has helped many of my friends and myself uncover hidden illnesses and provided treatment that is far safer and more efficient than some traditional methods. I am constantly trying to get my friends and family to see her. It saddens me how so few people are willing to invest in their health. If you are a person who values your health, you must see Dr. Diane ASAP! You won’t be disappointed!”
-Kristen D., Douglas, CO

“I came to [them] after decades (literally) of ailments, some of which the traditional medical community could diagnose but couldn’t treat or they couldn’t even diagnose. I’d been self-treating for years (at HUGE expense with some success but only reduced a few symptoms.) Nothing was going away.

My life was getting more and more isolated. I started work with [Dr. Diane] about 1.5 yrs ago and feel sooooo much better. I’m able to eat more food including fruit. I’m able to exercise rigorously which allows me to consume more calories and nutrients for healing.

The most impressive aspect of working with them is that their approach is MORE science-based than western medicine. Since my pcp was unwilling to do the detailed testing or unaware of what to look for, he and specialists never got the data needed to help me.”

“I’ve worked with [them] for the last year and have been very pleased! My symptoms resulted from mold exposure and, because of her own personal experience, Dr. Mueller related well with my situation. [Dr. Mueller] is so committed to helping patients heal and improve quality of life… What I love about the practice is they take a very individualized approach and I felt the doctors took extra time to research my particular issues and symptoms. In my experience, that is highly unusual and, therefore, greatly appreciated! I also want to add they are very fair with what they charge for their services as well as supplements. I never felt pressured to follow what they recommended – I always felt like they worked with me and if I chose not to purchase a supplement, I felt they were as committed to my well-being as if I had. My symptoms have improved and this would NOT have happened if I had not found [them]! I highly recommend the practice!”

“[Dr. Diane and her team] saved my life. I had gone to 20 top specialists over 3 years and was not able to get a correct diagnosis. They were able to correctly diagnose me within a week of my first visit and get me into proper treatment. I was very fragile at that point and don’t like to think about what would have happened if they hadn’t.

They spend many hours each week reading and keeping up with current research, something I feel all doctors should do. They think outside the box and are interested in finding root cause of problems and not just treating the symptoms.

In addition to their depth of knowledge and ability to properly diagnose, their compassion for health struggles has yet to be matched by any of the many health professionals I’ve seen. Finding them was truly a godsend and I will recommend them highly to anyone.”

“Dr. Diane took one look at my lab results and developed a plan for me to improve my health. She is the rare functional medicine practitioner. She has been so helpful. I am very glad I went to her. I really didn’t even realize I was feeling badly until I started to make changes she suggested to me. She’s been wonderful!”

-Ken T.

“Dr. Mueller’s approach to medicine is refreshing! There is only so much you can do with western medicine and in my life I was needing a new approach.  By addressing the whole body, nutritional diet factors, environmental factors, blood work, and incorporating ideas I had not previously known, I was able to break through with my conditions.  I am not only experiencing less pain in my life, but through the process of healing guided by Dr. Diane Mueller, I am now happy to say I have more consciousness surrounding how I eat, what to eat and when things are appropriate.  Living by example Dr. Mueller has a vibrancy that makes you want to learn and know more about your body and overall health.  I highly recommend her to anyone looking for new answers, a new approach to health, or in need of freedom from pain and limitations.”

“I have worked with a number of holistic/functional medicine doctors in the past five years to address ongoing health issues that I’ve had for decades. I had a Lyme and mold toxicity diagnosis before working with [them]; so when I found a free copy online of their book “How to Use Your Mind to Heal Mold and Lyme” I read it and then got an email for a free initial 20-minute consultation with Dr. Diane. The book impressed me so much because I felt like I was reading my own story (even though it wasn’t written by me). I had already done some very expensive Lyme/mold treatments at another clinic and they did help a lot. But that clinic told me you can’t heal yourself from Lyme. I got about 70% better at that clinic but was still not happy with the joint/muscle pain I was having and when I read the book I was convinced that if Dr. Diane could heal herself from Lyme (and essentially get rid of the chronic joint/muscle pain), then I could do so as well. I have worked with Dr. Diane for a year now and have been very happy with the care and the treatment processes… I am definitely on a healing journey and also recognize that I have further to go. I know that decades-in-the-making disease processes such as Lyme/mold can’t be reversed in just one year of treatment. I recognize that it’s essentially a lifelong commitment to reverse Lyme/mold and the systemic damage that it has done to my body. Partnering with Dr. Diane and [her team] in this healing journey has been incredibly helpful and very positive for me.”

“There are no words to express how grateful I am to Dr. Diane and her staff. After being exposed to mold in my home and receiving no answers from my pcp, I reached out to Medicine with Heart as a last resort. I literally thought I was dying! Dr. Diane walked me through everything, gave me hope and the tools to regain my health. Thank you for doing what you do! You and your team are simply amazing!” -Cherie Pitcock

“After working with 4 other functional practitioners, I’ve finally found my last stop! I’m so excited for my healing journey to progress! Thank you Medicine With Heart (Dr. Diane is at her new clinic, My Lyme Doc)!”


-Jill Cooper

I’m currently working with Dr. Diane for serious tickborne illnesses and mold issues. In my first month I have gone from laying in the bed most of the day and not taking showers to being able to cook for myself and take showers again. I have a long way to go, but I’m improved for the first time in three years, which is far more than I can say for all the 100s of conventional doctors I’ve seen who are totally clueless.

-Katie Watcher
“Medicine with Heart (Dr. Diane is at her new medical clinic, My Lyme Doc) is a fantastic functional clinic – all of the team is knowledgeable and helpful, and while the challenge of dealing with mold toxicity is going to be difficult, if you can wrap your head around the lifestyle-based approach they will offer, it will be life-changing.”

-Marshall Moose
“I am a local chiropractor who values collaboration between healthcare providers as there is no such thing as a one-size-fits-all when it comes to an individual’s health & well-being. I have referred some of my patients over to Medicine with Heart & they have been very well taken care of & speak very highly of their experience. I can’t say enough for how much I appreciate you guys & look forward to continually working together in the future!”

-Vinny Cuviello
“I am grateful to have answers. I will use the tools you all have given me to continue forward in my journey to beat Lyme disease. I have learned a lot and will use it in the future. I appreciate the support I was given with this. It kept me going when I wanted to give up. Thanks to everyone!”

-Bridget Wooten
“Medicine with Heart (Dr Diane is at her new medical clinic, My Lyme Doc) has been such a great experience for me! Not only have they uncovered underlying issues with my health, they have provided me so much 1-on-1 attention and assistance. I am feeling so much better and have so much more energy since starting with them.”

-Haley Peck
“I have been suffering from severe, suicidal anxiety for several years. Tried everything. Was even hospitalized. I was referred to Medicine with Heart (Dr Diane is at her new clinic, My Lyme Doc) by a friend. One of the many problems I was having, was Lyme disease. I can say I am finally feeling like the old me. When NOTHING else worked, Medicine with Heart figured it all out. I am beyond thankful and can’t recomment them enough.”

-Megan Nassir
“I thank you for providing me with such a positive and transformational experience! The Doctor was very knowledgeable and took the time to address all of my concerns. The environment was very warm and welcoming and the investment is worth it!”

-Patricia Boston
“The medical staff was very friendly and professional. The environment was clean and pleasant. The doctor was very knowledgeable and was able to explain things in a way in which I could understand. Overall great experience and completely worth the cost.”

-Christopher Godsey
“Staff was very friendly and helpful. Doctors are knowledgeable and work with you to determine the best plan for care. I’m so happy to have found a place that I feel cares about me.”

-Stephanie S.
“Love is Medicine! And the Medicine is plentiful at this clinic! I run a health and wellness channel on YT and highly recommend this group of clinicians because they have been trained in the leading edge sciences, like epigenetics, that show just how treatable “untreatable” illnesses truly are! They will encourage and support you along your journey to wellness because that is the mission that they have trained for – using cutting edge testing, treatments, and methods to make sure you overcome any of your health challenges, for good! Thank you Dr. Diane for everything you’ve done for me, your patients, the clinicians and doctors you train, and ultimately – the world! 🙏💙🌎”

-Darien Thomas
“My quality of life has improved immensely in a short period of time since I came to Medicine with Heart (Dr. Diane is at her new clinic, My Lyme Doc) clinic! I used to lose up to 2 days a week to migraines and intense fatigue from chronic inflammatory response syndrome symptoms (from mold exposure) Other doctors just said it was all in my head and told me that I needed to “see an allergist and a psychiatrist…”) but Dr. Diane have absolutely changed my life by treating the ROOT of the problem and basing it on the scientific evidence from my bloodwork…I feel better than I have in years … (and the last few have been full of huge health issues including healing 100% from cancer, freedom from opiod addiction (7 years clean now) and at one point, being on 14 prescription medications ….(yes, I said 14!) I was able to get off of my very last prescription a month ago and now am on ZERO prescription medications. No more throwing drugs at the symptoms! You have to FEED the ROOTS to bear delicious FRUITS.”

-Janet H.
“I was in decent health before I started seeing Dr. Diane. I had a few minor complaints (mild constipation, peeling skin on my fingers, a chronic cracking left nostril, to name a few) that were seemingly unrelated to one another. Through personalized supplementation, ALL of them virtually disappeared. We also discovered and staved off things that had been building toward something more serious in my system (pre-diabetes, pre-hypothyroidism, pre-kidney dysfunction). I am a true believer of Functional Medicine and would highly recommend the intelligence and heart-centered guidance of Dr. Diane.”

-Jessica Twerp
“Medicine with Heart (Dr. Diane is at her new medical clinic, My Lyme Doc) is a great place and I’m glad I found it! They look far beyond the surface level of problems, which is a major problem of today’s medical field. They are great to work with. We’ve had nothing but great experiences with Medicine with Heart!”

-Brian K.
“Dr. Diane found a gut issue that I’d never been tested for, even after I had been told I had “IBS” since I was 13 years old, and nothing was helping. She helped me change my diet and put me on supplements that have made a WORLD of difference. I now can move forward while: Knowing what is going to trigger my gut problems, not having to know where the nearest bathroom is at all time, and not being constantly bloated and uncomfortable. I’m so happy to have found a doctor that actually cares about my progress and how I’m feeling/what is working and what’s not.”

-Cat Alltop
“I have been diagnosed with SIBO and had terrible digestion issues. Dr. Diane has helped me already so much. I am practically in tears to have found [her]. Recommend them so highly to all my friends and family. 5 STARS!”

-Jacqueline Miller
“This is a functional medicine practice that not only has guided me in my own healing and restoration but has also enabled me to be an active partner and agent of change in the process. Every appointment I learn new and useful information while also feeling listened to. The multifaceted mind-body approach of Medicine with Heart (Dr. Diane is at her new medical clinic, My Lyme Doc) is the future of medicine, getting to the root cause of illness, empowering patients and supporting not only the body but also the mind and spirit.”

-Caroline Kelly
“Diane is one of the most gifted and intuitive physicians around with such a diverse education, and broad knowledge base to draw from, she is truly one of a kind. I would recommend anyone to go see her first before exploring the western side of medicine that at least for me seemed to enjoy keeping me sick. You will be glad you did.”

-Doug Davis
“I’ve seen many alternative practitioners over the years and haven’t found many people who have helped me, so I’ve become cautious when seeking someone new to work with. I’m very happy with my progress. Dr. Diane [is] very thorough, and knowledgeable. They practice different modalities, one of which is functional medicine, which I feel is so important to getting to the root of one’s issues. They have a relationship with my doctor/nurse practitioner and have consulted with them regarding my issues. I really appreciate that and feel like I have a team supporting me. I will continue seeing Dr. Diane as I trust them and am confident my issues will be resolved. I would also like to say that I like them personally. They have big hearts and are a joy to work with.”

-Connie Coffee
“Dr. Diane was the first person in my life to suspect and test for a condition that is fatal if not treated! I have immense gratitude to her and respect for her abilities. As it turns out the treatment is easy and, in Denver at least, no cost! And I feel great now, better than in decades. And the rest of my family is getting tested for this hereditary common condition, that for some reason, no other doctor ever even thought to look for in twenty years. Dr Diane had opened my eyes to a whole new life of physical health!”
