- Monitor your environment and exposures over time.
- Turn your data into evidence that counts.
- Join a protected cohort, not a silent statistic.
01 — The Problem
Pesticides, golf courses, and Parkinson's — what's going on?
Many golf courses apply pesticides and herbicides in quantities far exceeding typical residential or agricultural use. These chemicals can migrate into surrounding soil, groundwater, and air — reaching the homes and gardens of nearby residents without any warning or disclosure.
Emerging peer-reviewed research suggests a dose-dependent link between proximity to golf courses and elevated Parkinson's disease risk. Studies have found that people living within a mile of a golf course face measurably higher rates of diagnosis, particularly when those courses draw from the same water sources used by households.
Yet individual families have almost no way to protect themselves. They don't track their exposures over time. They only hear about class action lawsuits years after the damage is done. And on their own, they have almost no leverage against large golf course operators or chemical manufacturers.
Key Research — 2025
The Lancet NeurologyA landmark 2025 review in The Lancet Neurology by Dorsey, Tanner, Bloem et al. confirms that environmental factors — not genetics — play the dominant role in causing Parkinson's disease, with pesticides identified as the primary toxicant class. The authors explicitly call for "improved measurement of toxicant exposure in individuals" as a key prevention strategy.

"Environmental toxicants and Parkinson's disease: recent evidence, risks, and prevention opportunities"
Lancet Neurol. 2025 Nov;24(11):976–986. DOI: 10.1016/S1474-4422(25)00287-X
Dominant
Role of environment
Large-scale genetic studies confirm environmental factors — not genetics — play the dominant role in causing Parkinson's disease.
#1
Toxicant class
Pesticides are identified as the primary class of environmental toxicants implicated in Parkinson's disease development.
Largely
Preventable
The authors conclude that Parkinson's disease could be largely preventable with improved exposure measurement and policy action.
"The global burden of Parkinson's disease is rising. Large-scale genetic studies have confirmed that extrinsic or environmental factors, rather than genetic predisposition, play a dominant role in its cause. Increasing evidence implicates three classes of toxicants — certain pesticides, the dry-cleaning chemicals trichloroethylene and perchloroethylene, and air pollution — in the development of Parkinson's disease. These toxicants are widely prevalent, impair mitochondrial or lysosomal function, or both, and contribute to, if not cause, the disease. Parkinson's disease could be thus largely preventable."
"…improved measurement of toxicant exposure in individuals and the environment… can precipitate the fall of the burden of Parkinson's disease."
— Dorsey et al., Lancet Neurology, 2025
The researchers' call for "improved measurement of toxicant exposure in individuals" is precisely Sentinel's mission. We provide the personal exposure tracking infrastructure that this landmark study identifies as essential to reducing the Parkinson's burden.
02 — How It Works
How Sentinel works for you
Track your environment and health
- Share where you live and information about nearby golf courses.
- Optionally log basic health changes or concerns over time.
- Your data is encrypted and stays under your control.
Turn your data into legal-grade evidence
- Sentinel time-stamps and structures your information securely.
- We help build a clear picture of exposure patterns for your area.
- This evidence can support future legal, medical, or policy actions.
Join a protected cohort
- You're no longer isolated — you're part of a group facing the same risks.
- If credible legal or regulatory actions arise, you can be quickly informed and pre-positioned.
- You may be able to participate in remedies or settlements if harm is proven.
Sentinel does not sell your personal data. You control what's shared and when.
04 — Citizen Activation
Help build the case — and share in the upside
Sentinel only works if citizens are active participants, not just data points. We're building tools so that people living with risk can measure what matters, push for change, and participate in the value created when evidence leads to real-world action.

Questions you might have
If you don't see your question here, you can reach us through the waitlist form and we'll get back to you.
No. Sentinel is a data and citizen-protection platform that helps you organize evidence and connect with qualified legal partners when appropriate. We are not attorneys and do not provide legal advice.
No. There are no guarantees of legal outcomes. Sentinel helps you be prepared and informed — not promised a specific result. The value of joining is in documentation, awareness, and being positioned to act if credible opportunities arise.
No. You can start with just your location and basic information. Additional health data is always optional and entirely under your control. You decide what to share, with whom, and when.
We use modern encryption and strict access controls. Your data is encrypted at rest and in transit. You decide what can be shared and with whom — nothing leaves your account without your explicit consent.
During the pilot program, we may offer free or discounted early access in exchange for your feedback. Pricing for the full service will be announced before the pilot concludes, and early members will receive preferential terms.
Yes. We'll focus first on golf course communities, but you can join the list to hear about future Sentinel programs covering other environmental health concerns.
Sentinel is proactive, not reactive. Class action sites typically appear after harm is already documented and litigation has begun. Sentinel helps you build your record now — before anything happens — so you're in a much stronger position if action ever becomes possible.
