What to Expect
Our Emergency Care Process
From walk-in arrival to your next-step care plan, our Houston ER team keeps evaluation, testing and treatment under one roof.
Step 1
Walk In
Come directly to our emergency room in 77070 at any hour. No appointment or referral is required.
Step 2
Immediate Triage
An emergency nurse begins your assessment and identifies the level of care you need.
Step 3
Physician Evaluation
A board-certified emergency physician evaluates your symptoms, history and physical findings.
Step 4
Diagnostic Testing
When needed, on-site laboratory testing and imaging help the physician reach answers quickly.
Step 5
Treatment
Your care begins in a private treatment room with monitoring and treatment suited to your condition.
Step 6
Your Next Steps
Before you leave, the team explains the findings, follow-up instructions and next steps in your care.
The NorthStar Difference
Emergency Medicine Specialists
Every patient is seen by a specialist physician — the credential you would look for in a large hospital department, applied here in a far quieter setting.
A Room Of Your Own
Nobody is triaged into a corridor. A registered nurse begins your assessment the moment you arrive and you are shown to a private treatment room, which is the difference between waiting for treatment and actually receiving it.
Answers Before You Leave
Bloodwork and scans are performed and interpreted on site. Most people understand precisely what is wrong, and what happens next, before they walk back out to the parking lot.
Built Around Families
Infants, teenagers, parents and grandparents are treated by the same staff in the same building, so a family arriving together is never divided between facilities.
Our Clinical Team
Meet Our Emergency Physicians and ER Team
Every patient is evaluated by a board-certified emergency medicine physician supported by ER-trained nurses and diagnostic technologists. The team is continuously staffed so the same level of attention is available overnight, on weekends and during holidays.
Our physicians combine the clinical capabilities expected from a hospital emergency department with the calm, private setting of an independently owned facility. They take time to understand symptoms, explain findings and guide each patient through the next step.
Hospital-grade equipment, ER imaging and a certified laboratory help the clinical team reach answers during the visit instead of sending patients between separate appointments.
Located on Cypresswood Drive near Highway 249, NorthStar provides local emergency care for Houston families seeking a capable medical team close to home.
- Board-certified emergency physicians on site around the clock
- CT, X-ray, ultrasound and EKG performed and read during your visit
- A certified laboratory inside the building
- Open every one of the 365 days — no appointment, no referral
