Evolution of Wellness is a health content and services platform founded by Marcus Clark MPH. It includes a blog covering evidence-based health and habit-building, a free daily wellness app called The Reset Compass, professional services for health brands and organizations, and a curated list of personally used products. The name reflects the core principle: health knowledge is always evolving, and the guidance here evolves with it.

No. Marcus holds a Master of Public Health degree and a Lean Six Sigma certification, with clinical experience in physical therapy and personal training.

Yes. Every post that makes a specific health claim cites peer-reviewed sources. If a finding is preliminary, contested, or limited in scope, that is stated in the post. The goal is to translate research accurately, not to sensationalize it. Posts are for informational purposes only and do not constitute medical advice.

Sharing a link is always welcome. Reproducing full post text without permission is not. If you want to republish content, reach out at marcus@evolutionofwellness.com with details on where and how it would be used.

Yes, completely. No account, no email, no payment. Open it and use it. Try it here.

All data stays on your device using your browser’s local storage. Check-in history, streaks, XP, achievements, and preferences are never transmitted to any server. Marcus has no access to your app data. If you clear your browser storage or switch devices, your data does not transfer.

You check in on how you feel using a slider. The app maps your response to one of six states and generates a daily path across four pillars: Move, Fuel, Recover, and Mind. It also has a Quick Wins tab for one-tap habit actions, a streak system, XP, rank progression, and achievements. The goal is one small practical action matched to your energy and available time, every day.

Yes. It is a web app optimized for mobile browsers. Open it in Safari or Chrome on your phone and add it to your home screen for the closest experience to a native app.

Five services: health and wellness writing, health content review, supplement and ingredient research briefs, health program evaluation, and written movement and wellness assessments. All are delivered over email with no calls or meetings required. Full details and intake forms are at evolutionofwellness.com/services.

Submit an intake form on the services page for the service you need. Marcus reviews every inquiry personally and responds within two business days to confirm scope, timeline, and rate. No calls needed before work begins.

Yes. Illustrative samples for all five services are available at evolutionofwellness.com/services/samples. These use fictional clients and data to demonstrate format and approach. Real client work is available on request under NDA.

Some links on the What I Use page and in blog posts are affiliate links. A small commission may be earned if you purchase through them at no extra cost to you. Affiliate relationships are always disclosed. They do not influence which products are recommended — only products Marcus personally uses are listed.

Marcus does not accept content review or research brief work from brands whose products he actively promotes as an affiliate, unless the relationship is disclosed in writing before work begins and the client consents. If you are unsure whether a conflict exists, ask before submitting a service inquiry.

Every product on the What I Use page is something Marcus has personally purchased and used. Incoming affiliate partnerships are evaluated against personal use first. Products that Marcus would not use himself are not listed regardless of commission rate. The page notes when a partnership is active and when products are still under evaluation.

Email is the best way: marcus@evolutionofwellness.com. For service inquiries, use the intake forms on the services page rather than emailing directly — the forms ensure Marcus has everything he needs to respond efficiently. For general questions, use the contact page.

Within two business days for service inquiries. General email response times vary but Marcus aims to respond to all messages within three to five business days.

Occasionally, when the fit is genuinely right. Reach out with specifics at marcus@evolutionofwellness.com. Pitches without a clear connection to the Evolution of Wellness audience or mission are politely declined.
