Serving Chino Hills, CA
Chino Hills patients reach the clinic in roughly ten minutes by heading west on Grand Avenue over the county line into Diamond Bar. It is often a shorter and simpler trip than driving east to a hospital endocrinology department in Chino, Ontario, or Rancho Cucamonga.

Getting here
Roughly 10 minutes west on Grand Avenue.
Take Grand Avenue west from Chino Hills Parkway. Grand climbs over the ridge, crosses from San Bernardino County into Los Angeles County, and drops into Diamond Bar. Turn onto Golden Springs Drive and the clinic is at 23341 Golden Springs Dr, Unit 210, with free on-site parking.
Pick up Grand Avenue from Chino Hills Parkway or take the 60 west and exit Grand Avenue southbound. Both routes avoid the slower stretch of the 71 through Chino and keep the trip near ten to fifteen minutes outside of peak hours.
Follow Peyton Drive or Eucalyptus Avenue to Grand Avenue and continue west. Because morning fasting labs are common in a thyroid workup, most Chino Hills patients prefer the earliest slot and travel before Grand Avenue backs up at the ridge.

Why patients come in
Patterns we see specifically among patients travelling from Chino Hills. You do not need all of them to be worth an evaluation.
Chino Hills sits in San Bernardino County, and most local endocrinology referrals point toward large hospital-affiliated groups in Chino, Ontario, or Rancho Cucamonga with multi-month waits. Crossing into Diamond Bar buys a named physician and a faster first appointment.
A steady share of Chino Hills patients are women in their thirties through fifties who developed thyroid symptoms after pregnancy or as perimenopause began. Thyroid and sex hormones are evaluated together here rather than in two separate specialties.
Patients frequently arrive because a sibling or parent was diagnosed with Hashimoto's. Antibody testing gives a clear answer years before TSH drifts out of range.
Conditions and services
Why choose us
The default path for a Chino Hills patient is a referral into a hospital-employed endocrinology group, where the appointment may be months out and the physician list rotates. Visits are short, the focus narrows to TSH, and the plan rarely extends past a prescription.
Ten minutes west, this clinic works differently. Dr. Hitendra H. Shah, MD sees each patient himself, reads the full panel, and revises the plan personally at follow-up. Forty years of practice and more than 5,000 patients treated sit behind that continuity, and 106 patients have rated the clinic 4.8 stars.
The approach is functional and whole-person rather than protocol-driven: nutrient deficiencies, blood sugar, inflammation, stress, and sleep are examined alongside thyroid labs, because those are frequently the reason a technically adequate dose still leaves someone exhausted.
