What Patients Are Saying

  • Before coming to Natural Health, I was miserable and looking for hope. Natural Health gave me that hope. I was having hormonal troubles, struggling with my weight, and achy joints. I am 45 and these symptoms developed over the last year. I felt out of control with my body. Now, I feel more in control of my body. Through change of diet and proper supplements, I feel my hormones are coming more into balance. I have more energy and no longer depend on caffeine or energy drinks to get me through the day. I feel full of hope on my journey for optimal health and feel comforted that Natural Health is there to guide me through this. -G.B


  • Before coming in, I had stress issues, weight gain, I was tired/sluggish, and had severe mood swings, PMS, and cramps [around my period]. Now, my stress decreased, I haven't put on any more weight, and my emotions and cramps have decreased just before and during my period. -S.D


  • Symptoms I have been working on with Dr. Mark: I first came to see Dr. Mark for symptoms of weight loss, no energy, anxiety, irritable bloating, etc. I was going to the gym 3x a week and watching what I ate (as I know how) and the scales would not budge. How he has helped me? Dr. Mark has got my body unblocked – taught me how to eat and stay on track in a healthy way – I have lost 40 lbs and learned a new life style to continue on track. How to keep your body healthy by the things you put or don’t’ put in your mouth. What I have learned through this process: The #1 thing I’ve learned is the real healthy way to cook and eat. The difference between medical standpoints and the natural standpoint. How to be on a healthy, real life diet. ALH


  • What was it like before you came to see Dr. Mark? Before seeing Dr. Mark I was miserable. Intense stomach pains, headaches, and completely drained. I’m 26 years old and knew this wasn’t normal. I visited my doctor frequently and was prescribed medicine that did not help. I was sick and tired of always feeling sick and tired! How is it now? The nutrition program has helped tremendously! My stomach pains are nearly nonexistent, headaches are minimal, and I have so much more energy. I feel like a 26 year old should feel! I’m able to focus, I’m eating better, and I feel so much healthier. When others see me taking my supplements it seems they often have questions, so I do my best to educate them on the program and how much it has helped me—which I think is evident by my smile and enthusiasm to be healthy. Thank you Dr. Mark and everyone at Natural Health!

  • What it was like before I came to see Dr. Mark: I used to have headaches 24/7 for well over 3 years. I tried everything. I got every test imaginable. Had MRA, CT Scan, MRI, all the blood work you can have, seen an allergist. No one found anything. Acupuncture didn’t help. How it is now: Now I have lighter headaches to days where I actually have no headaches. I am improving. I still have a ways to go. I look forward to having no more headaches!
