Success Stories
I’m back in my old clothes! What a feeling!
"Best Fit Nutrition has helped me with weight that would not go away even after 18 months of watching what I ate and increased workouts. I had all this issue with my weight and now I’m back into my old clothes, what a feeling! I feel great, seasonal allergies disappeared, more energy, my skin looks awesome, and sleeping better.
I am very skeptical in general but have referred many people to Best Fit Nutrition because of my results. Thank you Joan."

"I wanted to take a moment to thank Joan for helping me feel better than ever! I’m 51 and healthy but the last few years my body just didn’t feel right. I was tired, not sleeping well, and could not shed the extra weight that I’d gained over the last five years."

"I will never forget March 30, 2001. It was my first meeting with Joan. It's the first time someone heard all my concerns and I realized this was the person who would help me find a way to overall wellness."
- Cindy
"Sunrise. Sun rays beaming on my face as I lay there in utter discomfort. “ Crap, another day”, I thought to myself. Another day of pain and discomfort, lack of energy and restlessness from the poor sleep I suffer with. This was my normal, my baseline. How at twenty-five years old has my body given up on me? Well, this was no easy story- it all started from my birth day."
- Geny R.
"Joan really showed me a new way of life. I was always uncomfortable in some way or another. I had bad gut issues, constant issues with UTI-like symptoms, anxiety, heavy periods, and that's just the shortlist!"
- Joanna S.
"I am happy to say I met Joan through my sister Marie... seeing the changes in her weight an wellness....made me want to go for myself. I finally made the commitment to go and meeting Joan has been the best thing that has happened to me in a very long time.
I admit I was nervous about going and afraid I would not be able to do it...."

I am 60 yrs old and never thought I could do this work, and yet I can and I am!
"Joan has been invaluable to me and I am so grateful for the work we are doing. As someone with a history of trauma, I have found that my nervous system had been in survival mode for forever. With Joan’s help and guidance, I am rewiring my body’s response and seeing the benefits in my sleep, my reactivity when under stress, and my body overall. I am 60 yrs old and never thought I could do this work, and yet I can and I am. A holistic approach is powerful and effective at the core, and as Joan rightly says, once healed it is permanent. So very grateful."
