Finding a specialist who actually listens—and I mean really sits there and hears the messiness of your symptoms—is getting harder. If you’ve been hunting for an endocrinologist in San Diego, you’ve likely stumbled across the name Jeffrey A. Sandler MD. He’s been around. Honestly, with over 50 years in the game, he is essentially a living archive of metabolic medicine.
But here’s the thing. Medicine isn't just about how many decades you’ve been wearing a white coat. It’s about whether the person inside that coat can solve the puzzle of your hormones when every other test comes back "normal."
The Man Behind the Lab Coat
Jeffrey A. Sandler MD isn't some new kid on the block using TikTok trends to explain insulin resistance. He’s a University of Illinois College of Medicine graduate, class of 1971. Think about that for a second. He started practicing when many of the technologies we take for granted today were barely sketches in a notebook.
After medical school, he headed West. He did his internship and residency at UCSD and then a fellowship at the National Institutes of Health (NIH). That NIH stint is a big deal. It’s the kind of place where you don't just learn how to treat a disease; you learn why the disease behaves the way it does at a molecular level.
He’s board-certified in Internal Medicine and Endocrinology, Diabetes, and Metabolism. He speaks English, German, and Spanish. That kind of range is rare, and it’s probably why his waiting room has historically been a melting pot of the San Diego community.
What He Actually Does
Most people see an endocrinologist for the "big three": thyroid, diabetes, or "my weight won't budge." But Sandler's scope is wider. We're talking:

- Thyroid Eye Disease: A condition that is as frustrating as it is visible.
- Diabetic Polyneuropathy: When the nerve damage from high blood sugar starts making your feet feel like they're on fire or completely numb.
- Gonadal Disorders: The stuff nobody wants to talk about at dinner but affects everything from mood to bone density.
One patient review stuck with me—someone mentioned they’d been getting the "run-around" for 19 years before Sandler "cracked the case." That’s the hallmark of an old-school clinician. They look at the patient, not just the printout.
Why Experience in Endocrinology is a Double-Edged Sword
Let’s be real for a minute. When a doctor has been practicing since the 70s, you get two things.
First, you get pattern recognition. A doctor like Jeffrey A. Sandler MD has seen thousands of cases of Hashimoto's or Type 2 Diabetes. He can spot an outlier from a mile away because he’s seen the standard version ten thousand times. He’s seen how drugs like Metformin or Levothyroxine work across generations.
The second thing, though, is the vibe. Old-school doctors don't always have the flashiest patient portals. They might not be the ones texting you emojis about your A1C. Some patients love the direct, no-nonsense approach; others find it a bit jarring if they’re used to the "concierge medicine" feel.
Currently, his practice is centered around the Hillcrest area of San Diego, specifically at 4060 Fourth Ave. He’s affiliated with major players like Sharp Memorial Hospital and Scripps Mercy.

The Real Talk on Reviews
If you look him up online, you’ll see a mix. Some people call him a "genius" and a "Guardian Angel" (he’s actually received the Guardian Angel recognition from Sharp HealthCare). Others complain about wait times or the office staff.
Is that surprising? Not really. In 2026, the medical system is strained. A specialist who takes his time with a "tough case" is inevitably going to run behind for the next person. It’s the classic trade-off: do you want a doctor who stays on schedule but kicks you out in 8 minutes, or one who stays until the job is done?
Beyond Just Blood Sugar
Endocrinology is basically the "IT department" of the human body. If the signals (hormones) aren't getting through, the hardware (organs) won't work. Jeffrey A. Sandler MD deals with the weird stuff too—things like Acromegaly (too much growth hormone) or Cushing’s Syndrome.
He also handles a lot of Diabetes with Renal Manifestations. That’s medical-speak for when diabetes starts picking a fight with your kidneys. It’s a high-stakes area of medicine where you need someone who knows exactly how to balance blood pressure, glucose, and filtration rates without crashing the whole system.
Navigating the San Diego Medical Maze
If you're trying to book an appointment, heads up. As of lately, some databases show him as not accepting new patients, while others (like Scripps AMG) suggest he is. It usually depends on your insurance. He takes Medicare and a ton of PPOs—Aetna, Cigna, Blue Cross—but he’s notoriously picky about Medi-Cal.

Basically, if you want in, you need to call the office at (619) 497-6188. Don't rely on a "book now" button on a third-party site. Those things are rarely updated correctly.
Practical Steps if You’re Seeing an Endocrinologist
Whether you end up seeing Dr. Sandler or another specialist, don't walk in empty-handed. Endocrinology is a data game.
- Bring the "Why": Don't just say "I'm tired." Bring a log of when you're tired. Is it after eating? Is it all day?
- The Med List: Not just the names, but the dosages. And yes, your "natural" supplements matter because they can mess with thyroid lab results (Biotin is a famous culprit here).
- Old Labs: If you have labs from three years ago, bring them. Trends matter more than a single snapshot in time.
Jeffrey A. Sandler MD represents a specific era of medicine—one built on clinical observation and a deep, foundational knowledge of how the body's chemical messengers work. In a world of "quick fixes," that kind of depth is worth the wait.
Next Steps for Your Health Journey:
To make the most of a consultation with a specialist like Dr. Sandler, compile a three-month history of your symptoms and a complete list of all supplements. Verify your specific insurance plan's "Specialist" requirements by calling the Hillcrest office directly to ensure they are currently credentialed with your specific sub-plan.
