Patient Testimonials

The best part of Functional Medicine is watching my patients heal. When the cause of illness is treated the right way, you feel better! Take a moment to listen from patients who have regained their health and found healing.

“I’ve been sick for 5+ years, hadn’t been in the gym for over a year, and Dr. Joe got me back to working out within three months!”

Response from Joe Mather, MD

It’s easy to help motivated and awesome patients like you, Jack. Makes my job a blast! Thanks for the review 🙂
“After my first visit with Dr. Mather, my gut issues started improving significantly within a week. He is no nonsense with his suggestions. I haven’t felt this good in years! I highly recommend him!”

Response from Joe Mather, MD

Thank you Amanda! 🙂 I’m looking forward to seeing you improve even more!

Renee Guidry

“We began seeing Dr. Joe Mather for my boys when we reached a point where holistic approaches alone (herbs, detox support, etc.) were no longer enough to help with mold toxicity and PANS symptoms. He was able to provide short-term medication support that truly made a tremendous difference during some very difficult times.

What we appreciate most is his bedside manner. Dr. Mather has always been kind, compassionate, and willing to listen. He is very open-minded and receptive to questions, concerns, and even holistic ideas or treatment suggestions I wanted to discuss. I never once felt unheard, dismissed, or rushed. Instead, he was always willing to collaborate and think through what might best support my children.

Finding a provider who is both medically knowledgeable and open to partnering with parents is rare, and we are incredibly grateful for the care he has provided our family.”

Response from Joe Mather, MD

Thank you Renee, it’s been a pleasure getting to know you and your wonderful family! Made my day to see your boys doing so well!

“Other doctors had been a waste thousands of dollars for no results. I had resigned to just feeling horrendous for the rest of my life- going to the bathroom 5-8 times a day, brain fog that effected my work, weakness, severe bouts of dizziness, pain in all my joints, constant severe bloating, struggled to lose weight, struggle to improve lifts at the gym. I had researched everything I could read, tried so many things for over a decade and failed to fix my issues. Dr. Joe significantly improved my quality of life with simple changes and putting together a program that I can follow. I was doing some things correct, but he put the puzzle together for me. He has given me my life back and it has only been a couple weeks. Bathroom only 3 times a day, pain is gone, dropping weight, bloating is gone, brain fog is gone, lifts are all up, and I am sleeping better. I had family and friends that I havent seen in some time saying I look better, healthier, etc. I am a 29 year old man and actively feel happier since I feel so much better.

Bottom line is this man fixed me when others could not and I had just about given up on ever feeling good. Literally fixed all my lifelong issues. Worth it does not even begin to describe it.”

Response from Joe Mather, MD

Yeah buddy! I told you that 2026 was going to be your healthiest year yet, and that it wouldn’t take that long to get you back. 🙂

Congrats, looking forward to seeing you at a followup!

Thanks so much for the amazing review!

“Dr Joe is the absolute best! Working with him feels extremely efficient. He runs the right tests and asks the right questions to get to the root cause as fast as possible. Highly highly recommend!”

Thanks Sarah!

“First, I have dysautonomia/ POTS for 12 years now. My Autonomic Nervous System malfunctions and it affects body systems like heart rate, blood pressure, digestion, body temperature etc. I have a pacemaker. But I didn’t initially see Dr Joe for this, as I have a cardiologist that helps me.

Let me add that I am sole caregiver for my husband (massive stroke 2018) but has recovered more than I thought he would! I handle everything in our home.

I started to see Dr Joe in April 2025 for my IBS that was diagnosed 4 years ago: having SIBO and hospitalized for a bowel obstruction during the first year 2022. I hadn’t improved much since then as my Gastro Dr offered only antibiotics for treatment. I lost 20 pounds and food was not my friend. My anxiety was through the roof and I was irritable and in pain all the time.

I saw Dr Joe at regular intervals addressing in this order; my diet, anxiety (gut/brain axis) and inflammation. With improvement, he introduced specific probiotics. At this point, I struggled a bit and he discovered I was sensitive to histamine which played a big part in my IBS. So he addressed that. Then he prescribed an herbal protocol which are natural antibiotics. Because he did each step gradually and didn’t dump it all on me at once, my body accepted it and began to heal. It’s been amazing to already be at 95% better.

Along the way, I was suffering with vertigo when I had an IBS appointment with him. I wasn’t going to miss it so I had someone drive me. And Dr Joes reaction when I showed up kind of nauseated and dizzy was, “ OK, we’ll treat the vertigo today too.” And he did and showed me how to do a simple maneuver at home to control it. Wasn’t expecting that.

I discontinued my HRT when I was really bad with IBS because I read somewhere that this might be adding to my discomfort. Now that I’m better, he has agreed to start me again with a low dose and increase as I can tolerate it. And he will continue to monitor it with lab work.
Dr Joe is very knowledgeable and a problem solver and he’s very good at it. He’s also helped with my POTS too. I’m so glad I found him and I highly recommend him to you!”

Written notes from patients who found healing.

"Dr. Joe, thank you! I'm feeling so much better! You know that I had been sick for 15 years. My regular doctors put me through all these tests and still couldn't help me. Then you figured it out within 20 minutes. It's really been life changing working with you!"

— Randy Dinan

"I came to the clinic because I thought I had gut issues, and thanks to you I found out it was mold, and I'm on the path to feeling better. I've spent 5 years trying to find out why I was sick, and I don't think I would have figured it out without you!"

— Kendra Linderbaum

"After COVID, I experienced a mysterious condition that worsened over 12 months and affected various systems in my body — I was unable to eat, work, or travel. A neurologist, gastroenterologist, cardiologist, immunologist, psychiatrist, and naturopath were unable to identify anything. Dr. Joe Mather identified a mycotoxin problem, later confirmed by lab tests. Now I'm recovering and feeling well again."

— Belizar Marinov

"On our first call, Dr. Joe had a strong indication, through simple, intellectual deduction, of what I was facing. He began gently with treatment. Four months later, my symptoms have improved greatly! When I first talked to him I feared a set of stairs and had no hope. Now I'm looking forward to playing with my kids and a possible summer return to running."

— Kamina Kiske

"I decided to meet with Dr. Mather after he diagnosed and cured my son, who was having severe allergic reactions to ant bites. We've discussed a plan to reduce my risk of heart attack and dementia — a goal that seems achievable is reversing calcium and plaque in my arteries, which I earlier understood was not possible. Dr. Mather prescribed medications, limited fasting, strength exercises, and some new supplements. Testing also revealed elevated lead levels in my blood, and he prescribed several oral supplements to chelate the lead. We expect my levels to be significantly lower in three months."

Let’s Get Started

A doctor who cares about science

Working as an independent physician gives me time to study and keep learning new ways to help my patients. I’m proud to have contributed to our understanding of the gut–thyroid axis in a paper published in 2022.

I graduated from Tulane University School of Medicine and School of Public Health in 2011 and completed my Family Practice training in 2014. I treat many conditions, with particular expertise in GI health and mold and heavy-metal toxicity. When I’m not with patients, you’ll find me playing with my three kids, exercising, meditating, or playing the drums.
