Hemera

Now accepting patients · Spring 2026

Cancer care,
walked together.

Hemera is a companion oncology practice — medical oncology, navigation and integrative support, gathered around a small caseload and an old idea: that a doctor who knows you by name makes cancer a different kind of hard.

The practice, in a sentence

A small oncology studio built around the kept promise: we will not hand you off, and we will not rush.

Navigator : Patient
1 : 22

Our navigators carry a capped caseload of twenty-two. Large networks average one to a hundred and fifty. The difference is the whole job.

Cases reviewed weekly
Every single one.

Thursday tumor-board. Your chart is read aloud to every oncologist, every pharmacist, every palliative-care lead in the practice. No case carried alone.

A letter from our director
"We do not believe cancer care is only about cancer. We believe it is about whose hand is in yours when the news arrives, and who picks up the phone on a Saturday night when it gets harder. We built a practice around that belief."
Dr. Salem Weiss · Clinical Director
The work

Four kinds of care,
one team carrying all of it.

We do not hand you off between silos. The oncologist and the navigator and the acupuncturist read the same notes and pick up the same phone.

01 / 4Clinical

Medical oncology

Board-certified oncology care for solid-tumor and hematologic malignancies. Treatment plans are written slowly and reviewed across a multidisciplinary team every Thursday.

02 / 4Companion

Cancer navigation

A navigator assigned to every patient from diagnosis onward. Appointments coordinated, insurance fought, scans followed, questions answered — the work most clinics outsource, we carry.

03 / 4Integrative

Integrative support

Acupuncture, nutrition, psychotherapy, and pain management are folded into the treatment plan — not offered as extras. Everyone on the team reads each other's notes.

04 / 4After

Survivorship

The years after treatment matter. Annual reviews, long-term surveillance, and a kept relationship with the team who walked with you — for as long as you want.

stay with us.

01

"They called me on the drive home from scan day to say the scan was clear. They knew I was driving and would not be able to open a patient portal. Someone remembered that."

A. Stein, 58 — Stage III breast cancer, 4 years clear
02

"The same navigator sat with me at every infusion for six months. We talked about my grandchildren. We talked about how afraid I was. We talked about nothing at all. It was everything."

Imelda O., 69 — NSCLC, in active care

"My husband died in December. The team came to his memorial. My oncologist cried. I cannot explain how much that mattered."

Common questions

Before you call.

  • You or your referring physician sends us records. Our navigator reads them, calls you within two business days, and schedules your first visit — a 90-minute conversation before any treatment is planned. We accept new patients continuously. Most are seen within seven days of referral.

Please be in touch

Come in.
Or call first.

A first conversation with Hemera is a 30-minute phone call with our clinical lead. No records required. No commitment. A real person who will listen, and, if we are the right practice, will plan a first visit for you.

We reply the same business day.
