Defy is for you if...
✔️ You leak when you laugh, sneeze, jump, or run.
✔️You have nagging back, hip, or pelvic pain.
✔️ You feel pressure, discomfort, or prolapse symptoms and don’t know what’s safe to do.
✔️ You constantly feel tense or weak, no matter how much you stretch or strengthen, nothing changes.
✔️ You’ve been told to “just do Kegels”—but they haven’t worked (or made things worse!).
✔️ You’ve tried YouTube videos, PT, or core workouts—but still feel stuck and frustrated.
✔️ You want a real solution that considers your WHOLE body—not just band-aid fixes.
Hi, I’m Dr. Melissa,
pelvic health physical therapist, yoga teacher, and founder of Defy.
I created Defy for individuals who’ve tried everything — and still haven’t found relief.
“I’ve seen doctors, done the Kegels, tried every stretch on YouTube, and I still don’t feel strong.”
Like so many, I was told to live with leaks and hip pain. But I refused to accept that as the norm.
Defy was created to give you something different. Not just more exercises, but a deeper, smarter way to reconnect to your body.
▪️A full-body, root-cause approach
▪️That blends science, strength, and self-awareness
▪️And actually works — without making your symptoms worse
Because you deserve to move, laugh, lift, and live without fear or limitation.

Hi I'm Dr. Melissa!
The founder of Defy and MSUNN Yoga & Wellness, with the desire to bridge the gap between fitness and rehab!
I truly understand the struggles with pelvic health as I was a physical therapist in my early 20's, no children, and struggling with hip pain and bladder leaks while exercising. I couldn't seem to figure it out and my doctors told me to stop running. I said 'no thank you,' and dove deep to discover pelvic health! What a complete game changer.
I no longer struggle with hip pain, run as long as I want, and don't have those pesky leaks with sprinting or jumping.
Now I am teaching others the healing powers of truly knowing how to use your core and pelvic floor to get back to the activities they love.
My grandparents are in their 80's still downhill skiing, kayaking, golfing, hiking, and kicking my butt while they do it! I want to stay strong and healthy as I age to be just like them!
My goal is simple, I want all women to feel empowered, supported, heard, and their strongest self no matter what stage of life they are in! So they can stay active in their 80's and beyond💗
