Founded by Dr. Poonam Desai, a renowned longevity clinician,
Sumero makes expert, clinician-led care something you can actually reach.
Here's what nobody tells you about online health: most platforms are apps first and medicine second. The prescription is a transaction. The "care team" is a logo. And the clinician whose name is on the site often had nothing to do with how any of it actually works.
Sumero was founded and built by Dr. Poonam Desai, DO, a practicing physician who designed every part of how care is delivered, from the clinical standards to the way ERO supports you. The medicine here isn't outsourced. It's the foundation.
She spent nearly two decades as an emergency physician at a Level 1 trauma center in New York City, and eight years as academic faculty at Weill Cornell Medical College. She watched preventable disease arrive in her trauma bay, over and over, years after the moment anyone could have changed it.
In 2017 she started practicing longevity medicine. Sumero is what that work looks like when the medicine, not the app, comes first.
When a physician builds the platform, the incentives change. The question stops being how fast can we write a prescription and becomes what actually keeps this person healthy for the long run. That kind of care is rare. It's exactly what Sumero was built to deliver.
Founder, Sumero Health
What we do
Hormone optimization, GLP-1s, longevity therapies, biomarker testing, & supplement guidance to help you understand your biology and stay ahead.
Preventive care, prescriptions, and lab review. Ongoing care that watches your trends over time instead of treating you once a year.
Everyday issues, handled fast. Colds, infections, rashes, and the small things that come up, without a trip to a clinic.
Care, made accessible
Most medicine waits for something to break. Sumero looks earlier, at hormones, metabolism, and the trends that shape your future, so you can act while it still makes a difference.
Video visits, messaging with your care team through ERO, around the clock. Your labs, your plan, and your history in one place, yours to see anytime.
The care people usually piece together from a longevity clinic, a primary care office, and an urgent care line, brought together and connected.
The depth of care that used to sit behind concierge pricing and a handful of clinics, made into something far more people can actually get to.
The best time to take your health seriously is long before anything goes wrong.
Dr. Poonam Desai, Founder of Sumero
Sumero takes its name from the Latin sum and ero, I am and I will be. But longevity lives in all three tenses. Who you were, who you are, and who you are becoming. Most of medicine only looks at this moment. We are built to see the whole line.
Your health, elevated
How we work
Every plan is overseen by a licensed clinician. ERO organizes your information and points you to the right care, but people make the medical decisions.
We tell you what the science actually supports and where it does not. No hype, no overpromising, and no selling you something you do not need.
Treatment is recommended when it is clinically appropriate, never by default. Sometimes the best answer is to adjust, to wait, or to do nothing at all.
HIPAA-compliant and encrypted. Your health information is private, secure, and never sold.
Sumero provides longevity and consultative care and coordinates with your primary care clinician, rather than replacing them.
Care that follows your trends across the year, retests and adjusts, instead of resetting at every new appointment.
