I had been suffering with chronic pain, fatigue, and fibromyalgia since having a reaction to the Covid-19 vaccine. I chose to see Dr. Regan because she would be able to do serious testing to discover underlying issues.

With the results she has been able to treat me with supplements, medications and diet change. Within a month my pain has been reduced by 90% and my energy has greatly improved. I feel GOOD for the first time in years!

The Functional Health of Lancaster team helped me heal from a diagnosis of ulcerative colitis! I wasn’t finding answers about the root causes of my inflammation, fatigue and rectal bleeding with traditional GI specialists.

Through the combination of guidance from Dr. Regan, along with supplementation, mind- body therapy, and nutrition I feel like myself again in less than 1 year!

I had the Energy Boost IV therapy; this is my second time doing it here at Functional Health of Lancaster and without a doubt it is one of the best things I have done for my personal wellness. I felt the difference immediately after each session.

It’s like having an energy drink with no crash that lasts about 10 days or more! I would recommend this treatment for anyone feeling down or lethargic or that just needs an energy boost to get them through the week.

IV therapy was a great experience, I instantly felt more energized! With IV Energy boost I’ve been able to replenish the vitamins & nutrients back into my system. I recommend anyone who is feeling “sluggish” to try!

I had an incredible experience working with Dr Regan! I needed help resolving issues of chronic pain and fatigue due to autoimmune disease, digestive disorders, and treatment for acute Lyme infection. Dr. Regan was very thorough in her assessment, asking many questions and taking time to answer all the time. I could tell that she genuinely cared about my progress and was very knowledgeable. Dr. Regan's holistic treatment plan involved a supportive team of professionals, including a nutritionist, yoga therapist and a health coach who are all amazing to work with!

The whole team was fantastic, including the support staff who went out of their way to provide a warm and welcoming atmosphere, orchestrating appointments and reminders and billing seamlessly. I believe that having the mind, body, and nutrition avenues covered were integral to my overall success. With Dr Regan and the team's help, I was able to make an 80% recovery in a matter of months! My sleep is improving, my strength and energy is returning, my gut health has improved significantly, plus I don’t have constant pain and brain fog anymore. It is just a bonus that I have lost at least 40 lbs. in this process!

I am forever grateful for the comprehensive care and support I received at Functional Health of Lancaster, and I wholeheartedly recommend Dr Regan to anyone seeking personalized and effective functional health solutions.

I came to Dr. Regan’s office with digestive issues, low energy and chronic pain! She had me do blood work and hormone testing. After meeting with her, the nutritionist and yoga therapist, I feel great!

My symptoms improved and I have more physical and mental energy with less pain. I am happier and healthier!

I am pleased to report that in one year I am doing so much better. My cholesterol is down, and my pain is gone. The fatigue I was struggling with is also gone!

I had a positive ANA test that is now negative. I appreciate the time and attention that Dr Regan took with me.

My digestion, heart palpations and stress have greatly improved under the combination care of
the practitioners at Functional Health of Lancaster. Wonderful thorough testing and treatment combined with yoga and nutritional evaluation have made a significant difference. Thank you all.

I came to FHOL in desperation to the cause behind my chronic fatigue and chronic pain! I had several tests done through my family physician that came back “normal” and lost hope as my situation become progressively worse without any answers.I struggled for 5-6 years and became essentially bed-ridden with no hope in sight.

After working with the staff at FHOL the last few months I have drastically improved by 75% or more! I’ve started working out again which I thought would never happen and it’s all thanks to FHOL I’m getting my life back and it feels good!

In a matter of 5-6 months my general health has increased 100%. By following Dr. Regan’s advice and supervision I feel better than I have in years. I highly recommend Functional Health of Lancaster to everyone!

Functional Health of Lancaster has been able to help me heal when mainstream health care threw up its hands. We all need healing of mind and body together and their holistic approach has saved my life.

Yoga therapy has helped me connect my mind and body and nutrition has helped me nourish and heal my soul. We cannot view mental and physical health as separate parts of ourselves. Functional Health of Lancaster has helped me see that truth!

Rachel is great; it has been so good learning new techniques and better ways to handle anxiety through movement! The body and mind are so powerful together and she really helps me tap into that. I would 100% recommend yoga therapy.

Dr. Regan listens to your health concerns and looks at your overall health. She didn’t just throw supplements at me but helped to lower my cholesterol. We also worked on fixing my hormone issues. I highly recommend F.H. if you want to stay away from drugs.

Yoga Therapy was a revelation. I realized I had made STRESS my normal state or condition.  I needed to learn ways to tone it down, tune it out, dissipate it, if I was going to be healthy and strong. I learned to BREATHE and with those breaths, listen to my body and learn to relax myself. I can do that anywhere - in the car, in the grocery line, when caring for the grandbabies.

I no longer take anything to sleep (melatonin). I center my thoughts, regulate my breath, relax myself. I have gone off high blood pressure meds that I have taken for almost twenty years.

I sought out the services of Dr. Regan and Functional Health of Lancaster for a new approach to ongoing GI issues, fatigue, brain fog, headaches and anxiety.  I appreciate the gentle and informed approach to finding root causes and not just treating symptoms.

After some testing, learning yoga therapy techniques, and making changes in my diet I am feeling better than I have in many years.  I have more energy, less fatigue, my headaches have gone away, and my anxiety has lessened in just a few months.  These changes have made a huge improvement in my overall wellbeing. Thank you!

Functional medicine changed my life. I was losing weight, unable to digest any foods, weak and tired. I did not know the body I was living in. Good testing and gut science made all the difference. I was skeptical when it came to all the supplements, but I looked into the research at world class institutions.

They (supplements) helped. Attention to diet, trigger foods and stress helped. Functional medicine changed my life. This is the happy truth!

I came to FHOL because of some gut issues that no other doctor was able to diagnose. My symptoms almost had me in tears! Dr. Regan ran tests that were never offered to me previously and quickly developed a treatment plan that didn’t involve harsh drugs with worrisome side effects.

I started to instantly feel better and was finally hopeful about my health. Within a short amount of time my gut feels great, my rashes are gone and any metric that you can use to measure someone’s health has improved. I am forever grateful to Dr Regan for giving me a new lease on life!

Dr Regan is thorough. She works with you to achieve health goals and keeps you accountable.

I was so excited to find a functional health PCP with a membership program that is affordable! I have had really bad experiences with PCPs in the past so I was hesitant at first, but Dr Regan blends functional medicine and regular PCP practices together so well!

I feel comfortable and welcome here and I am hopeful to work through my health concerns in a way that works well for my body!

I came to FHOL initially for infertility and hormone imbalances. Dr Regan helped me with finding the root causes of my health issues. After working with her for 9 months my cardiometabolic health has improved! I now have regular periods and I’ve lost 25 pounds. I’ve done all of this by changing my diet and lifestyle.

I started seeing the nutritionist who helped me really break down what I could do with my diet and lifestyle even further to help make these changes. I am so grateful for all of their help!

I have had a wonderful experience here. I feel like I am actually listened to and my personalized treatment really addresses the issue itself and not just symptoms.

Everyone here is friendly and professional. I am presented with options and I am able to be a participant in my care (unlike the corporate experience). I have nothing but gratitude!

I went to see Dr. Regan when I felt like my family doctor didn’t have any answers as to why I was feeling tired all the time. Dr Regan figured out that I had a parasite. I was Iron and Vitamin D deficient and had gut dysbiosis! I am feeling a lot better after following her treatment plan.

After dealing with Hashimoto’s Disease for over 15 years, I finally found a practice that was willing to look at the whole picture versus just prescribe one medication. Dr Regan helped me feel the best I have in years!

It’s wonderful to have your attention in my care and not feel rushed in or out of an appointment. Your staff is pleasant and helpful!

In the six month I’ve been seeing Dr. Regan my A-fib has gotten so much better. I can go through my entire day and not have an A-fib episode. Sometimes I completely forget about A-fib!

“After years of seeing various specialists, Dr. Regan is helping me pull all aspects of my health together. She is working with me to find the root cause of what has become multiple health issues.

Along with her team, she is guiding me toward my overall well-being and I am finally hopeful that I am heading in the right direction.”

“Functional Medicine is a beautiful way of caring for our whole bodies.

Dr Regan and her staff take the time to really listen to my health concerns and dig to find the root causes and not just use a ‘band-aid’ for a temporary fix.”

“I came here one year ago with headaches, high cholesterol and insomnia among other issues. Dr. Regan helped me with everything!

She is personable, caring and explains everything in great detail. I highly recommend!”

“One year ago, I came to see Dr. Mary Regan for high blood pressure. She put me on a special diet & supplements and one year later I am 43 lbs. lighter, normal blood pressure, and on 25%of my blood pressure medicine. I am grateful for the patient care I received.

My wife and I areappreciative for Dr. Regan. I feel great and look good as well! Thank you!”

“After suffering for more than 10 years with gastrointestinal issues I finally found some answers here at FHL. Dr Regan treated the root causes for my problems, not just the symptoms! I have not been able to find this relief from traditional doctors.

I feel like more than just a patient here at FHL. I’ve been following Dr Regan’s guidance and in just 3-4 short months I feel like my life is back on track and pain free! With my greatest gratitude, thank you FHL!”

“I have finally found a (provider) that cares, listens and fixes health issues. Dr. Regan is one of the best (providers) I have been to. I’m comfortable with her, I can say anything, and I have already recommended her other people I know with health issues.

Finding this practice was a God Send! Thank you to all who work here!”

“I’ve struggled with my weight, fatigue, gas, and bloating for the last 5 years for more. With the labs done, thorough history, and listening to what I had to say, my symptoms have greatly improved. I’ve lost 14 pounds; my labs and vitals have all trended in a positive direction.

My favorite part of functional medicine was getting to the root cause of the issues I was having and learning about my body. Functional medicine should be on everyone’s radar. You can become the advocate for yourself. The whole picture is looked at and treated.

They are there for you and really want you to get better and have the best healthiest life you can have!”

“Dr. Regan is great! I have seen her for many years. I love that she listens to me and follows up appropriately. She takes her time and is very knowledgeable of alternative options.

Functional health is wonderful. All my needs are taken care of by Dr. Regan.”

“I have been a patient at Functional Health of Lancaster for about two months, Dr. Regan has been wonderful. She really listens and takes the time to really explain test results and works to get to the bottom of what is causing your health issues.

Dr. Elia is very thorough when discussing and explaining nutrition and tailors her approach to you. After two months I am really feeling a difference in my energy levels, mood, and my aches and pains have reduced. I even lost a little weight! Yoga therapy is AMAZING, I really feel more in tune with my body.”

“When I first started with Dr. Mary, I was having terrible stomach problems with sudden diarrhea. I was becoming afraid to leave my house because of a couple of embarrassing incidents. I had seen several different doctors and never got better. Dr. Mary found that I have a gluten sensitivity and a sensitivity to peanuts and eggs.

By taking supplements and avoiding those foods, my diarrhea went away, and my skin cleared up. I am not perfect with following the diet, but when the symptoms return, I know why. Thank you, Dr. Mary, for your help!”

“Since I have been seeing Dr. Mary all my issues with digestion and IBS have been resolved. I am no longer afraid to go out to eat or even out of the house for fear of having a bathroom accident.

I feel more energetic and positive about my improving health issues.”
