Endeavor Health has announced the acquisition of Diamond Headache Clinic to form a new centre and expand headache and migraine care.
The new Endeavor Health Diamond Headache & Migraine Center will operate physician offices in Chicago and Glenview, with inpatient care available at Northwest Community Hospital in Arlington Heights (NCH) in a newly renovated space.
The new unit was designed for Diamond’s inpatient programme.
This acquisition will enable Endeavor Health to further its Neurosciences Institute and strengthen its capabilities in providing specialised, coordinated and accessible care.
Diamond Headache Clinic provides headache and migraine treatments to patients in Chicago, the Midwest and across the US. It has advanced practice providers (APPs) and a team of physicians, offering biofeedback, acupuncture, infusions, dietary guidance, Botox, oral and injectable medications.
The clinic also provides options, including nerve blocks, massage therapy, psychological intervention and physical therapy. Its tailored approach ensures customised treatment plans for each patient.
Endeavor Health Northwest Community Hospital president and Endeavor Health Neurosciences Institute system executive David Rahija said: “Endeavor Health is proud to welcome Diamond Headache Clinic, a respected provider of headache and migraine care with a strong reputation regionally and nationally, into our healthcare system.
“This combination of Diamond’s expertise and Endeavor’s comprehensive resources reinforces Endeavor’s commitment to providing world-class, expert care close to home for our communities.”
Diamond’s research department is continually working on the development of advanced therapies for headache and migraine management.
Founded by Dr Seymour Diamond in 1974, the clinic originally served a small population with few dedicated physicians.
In April 2025, Endeavor Health announced the launch of a cloud-based digital pathology platform, developed in partnership with Google Cloud.
