Getting here
Roughly 15 minutes via Brea Canyon Road or the 57 Freeway.
Take Brea Canyon Road north from Imperial Highway. The road climbs over the hill, crosses from Orange County into Los Angeles County, and reaches Diamond Bar. Turn east on Golden Springs Drive to 23341 Golden Springs Dr, Unit 210, with free on-site parking.
Head north on the 57 and exit Diamond Bar Boulevard, then connect to Golden Springs Drive heading west. This is the fastest option in the morning and takes most Brea patients about fifteen minutes.
Take Carbon Canyon Road to Chino Hills Parkway and Grand Avenue, then west into Diamond Bar. It is a scenic route and a reliable alternative when Brea Canyon Road is congested at commute hours.

Why patients come in
Patterns we see specifically among patients travelling from Brea. You do not need all of them to be worth an evaluation.
Brea is in Orange County, and local thyroid referrals lead into large Orange County health systems. Patients who want one physician following their case from testing through maintenance often prefer the short trip north instead.
A large share of Brea patients are men and women in midlife whose fatigue, weight change, low libido, and mood shifts have been assigned to one hormone system at a time. Thyroid and sex hormones are assessed together in a single plan here.
Subclinical results — a slightly elevated TSH, positive antibodies with normal hormones — are a common reason for the drive. Those patterns deserve a plan and a monitoring interval, not a shrug.
Conditions and services
Why choose us
Note for Brea patients: the clinic is in Diamond Bar, which is in Los Angeles County's San Gabriel Valley, not Orange County. That short hop over the hill is what separates a hospital-employed endocrinology group from an independent, physician-led practice.
Inside a large system, your thyroid care is a series of appointments with whoever is on the schedule. Here, Dr. Hitendra H. Shah, MD — 40+ years in practice, more than 5,000 patients treated — is the only physician you see. He reads the panel, explains it, sets the plan, and adjusts it himself.
The clinic's 4.8-star rating across 106 patient reviews reflects that continuity, and the functional, whole-person approach means nutrition, vitamin D status, metabolism, and stress are treated as part of thyroid care rather than separate problems.
