An Integrative Approach  With Zero Patience For Mediocre Support

Your care plan should be rooted in answers that come from comprehensive functional testing by someone who zooms out and offers real solutions, not just management AND does it in the right order

Because you’ve got better things to do than chase symptoms.

Over the past 15 years, I’ve worked with more than 20,000 patients and heard the same frustrations an repeat:

  • Worn out from bouncing between specialists.
  • Fed up with playing medication whack-a-mole.
  • Tired of being told your (surface level) labs are ‘normal'

And left wondering:
“If everything’s 'fine,' why do I feel everything but fine?”

I’m not here to hand you another generic protocol or tell you blanket statement advice you already know like "eat from the rainbow" and "try stressing less."

I’m here to keep digging until I figure out pinpoint the dysfunction, and then do something that is highly targeted.

Because real healing means asking better questions, challenging the system, and refusing to settle for half-answers.

Here, we get to the real root of what’s going on to get you the energy, clarity, and peace of mind you’ve been chasing for way too long.

I can’t say enough good things about Katie! I’ve been dealing with health issues for years, trying to piece things together on my own with little success. Katie not only helped me get to the bottom of it all, but did so with incredible patience, kindness, and expertise. She explains everything in a way that’s easy to understand and walks you through each step with care and confidence. I finally feel like I have answers and a plan that actually works. So grateful to have found her!

I’ve worked across the healthcare system from endocrinology to pharma, and I’ve seen the same story play out again and again: Women dismissed, overlooked, gaslit, or told “everything looks fine” when everything felt off.

It wasn’t until I hit my own health rock bottom that I realized I (and the entire traditional healthcare system) needed a better way. That’s when I found functional medicine and healing.

Now, I help people like you stop chasing symptoms and start getting the real, thorough guidance they need. I bring science-backed strategies, deep clinical experience, and the dedicated support you should’ve gotten years ago.

If you’ve been brushed off or are in a constant health spiral, you’re in the right place. Let’s get to the root and help you feel like you again.

I’m also a mom, a health nerd, and will absolutely side-eye anyone who thinks a 7-minute appointment can fix 7-year problems.

Hi, I’m Katie Driessens

- Grace Wood

"I highly, highly recommend Katie (Dietetics with Driessens) - she is absolutely amazing!"

I have been working with her for almost a year now, and she has completely changed my health, my gut, my knowledge of my body - everything. We also had mold in our house that I never would have thought to check for unless I had been working with Katie! It's very easy to schedule appts with her, and during our video chats, she is SO attentive, really listens, and we always make the most of our time together. She is never pushy with any recommendations or anything - she knows the functional medicine journey is a long one and takes some time to digest everything (no pun intended!). We have taken it step by step together, and still have a ways to go - but I have already felt such improvements in my body & my life.
