About Us
Our mission is to achieve your health goals
Physician-Led Leadership
Advanced Diagnostics was founded and is still governed by practicing physicians. Clinical decisions stay in the exam room—free from bureaucratic layers—so your treatment is guided solely by medical expertise and what's best for you.

Coordinated Care
Every specialist, nurse, and therapist involved in your case shares one record and one plan. Continuous communication means fewer repeat tests, clearer answers, and care that focuses on your overall well-being—not just a single condition.
Comprehensive Facilities
Three hospitals and six clinics in Houston and Dallas offer 24-hour emergency departments, surgical suites, multispecialty clinics, and state-of-the-art imaging—all under one roof for maximum convenience.
In-Network Coverage
We accept most major insurance plans, including Medicare and workers' compensation, so first-class care remains accessible and budget-friendly.

ASPN
Independent Practice, Administrative Support

The Advanced Surgeons & Physicians Network (ASPN) is a nonprofit group built by Advanced Diagnostics to keep independent doctors independent—without the paperwork overload. Choose turnkey practice-management or pick only what you need: billing, credentialing, scheduling, supply chain, marketing, analytics. While we run the back office, you keep full clinical control and gain system-wide resources—state-of-the-art hospitals, modern clinics, and leading-edge technology, plus flexible schedules and peer support. Focus on patients; we’ll handle the rest.
