You’re not imagining it.
And we can prove it.
If conventional medicine has dismissed you, brushed off your symptoms, or told you your labs are “normal” while you feel anything but — you’re in the right place. We use precision functional testing and root-cause clinical investigation to find what’s actually happening in your body. Then we fix it.

“Several years ago, conventional medicine almost gave up on me. That’s why I’ll never give up on you.”
I was the patient. Now I'm the clinician.
Several years ago, I was a high-performing clinician with debilitating neurological symptoms. Brain fog. Tremors. Joint pain. Cognitive decline.
I went to specialists. Multiple MRI lesions were found. Every test came back “normal.” I was told my symptoms were stress. Then anxiety. Then I needed antidepressants.
No one was investigating why. They were just managing the label.
Six months later, an IGeneX test revealed what conventional serology had missed: Lyme disease and co-infections — the same test most clinics still don’t order.
I treated it with a protocol that blended conventional antibiotics, strategic herbal medicine, nutrition, peptides, and lifestyle medicine. Within 8 weeks, my symptoms began reversing. Within 6 months, I was symptom-free.
The bigger realization: conventional and functional medicine aren’t enemies. They’re incomplete without each other.
I built GrassRoots to be the clinic I needed back then. A place where patients aren’t dismissed. Where testing is precise, not perfunctory. Where we don’t choose between conventional rigor and functional depth — we use both.
Not another wellness clinic. A clinical operating system.
Most functional medicine clinics run the same panels, recommend the same supplements, and produce the same vague results. We rebuilt the model from the ground up.
Precision functional testing
We use Genova Diagnostics, Doctor’s Data, US Biotek, IGeneX for tickborne illness, Vibrant Wellness, urine mycotoxin panels, salivary cortisol, and leaky gut markers. We test what answers questions — not what insurance “allows”.
Metabolic optimization, not just weight loss
GLP-1s can work — but only with muscle preservation, PNOE metabolic testing, InBody body composition tracking, and progressive strength protocols built in.
Conventional + functional integration
Your case needs antibiotics? We prescribe them. Needs herbs and nutrition first? We do that. Needs both? Standard protocol. We blend evidence — not ideology.
Comprehensive intake — included
Bloodwork, PNOE metabolic testing, and InBody body composition are included in your intake assessment. Most clinics charge separately for each.
Strategic peptide therapy
Peptides aren’t a trend — they’re a tool. We use them strategically for tissue repair, immune modulation, neurological support, and metabolic health, with proper oversight.
Real lab interpretation
No “normal range” hiding. We dig into optimal ranges, pattern recognition, antibody trends, and root-cause clues that standard reads miss entirely.
The illnesses other clinics miss or mismanage.
If you’re chronically symptomatic and your labs keep coming back “normal” — there’s a strong chance one of these is at the root of it.

“I’d been on thyroid medication for seven years with no real improvement. Dr. Osgood looked at the full picture — gut health, adrenal function, food sensitivities — and rebuilt my protocol. I feel like myself again.”

“Conventional rheumatology said my Lyme was “cured.” IGeneX testing showed active co-infections. Dr. Osgood’s integrated protocol — antibiotics, herbs, peptides, lifestyle — cleared it. No brain fog. No fatigue. No compromise.
