Integrative medicine · Rockville, MD

You’re not imagining it, and you’re not out of options.

You came here looking for answers, and you are not the first. Most people find us after normal results and a body that still does not feel right, or after being told to live with it. We take the whole history, look at how your symptoms connect, and say plainly what we think is going on.

Where to start

Tell us what you are dealing with, and we will tell you where to start.

Most people reach out unsure whether we treat what they have. Choose the description closest to your situation and we will show you which provider handles it, what we look at first, and what a first visit involves.

Dr. Spiegel

Pain is running my calendar.

You’ve stopped saying yes to things because you already know how you’ll feel after. We look at nerves, joints, and how you move, not just the spot that hurts.

Sleep, digestion, and focus have all slipped.

Brain fog, poor sleep, GI issues, and inflammation often trace back to the same underlying problem. We test past the standard panel to find what is actually driving it.

My hormones changed, and so did I.

Perimenopause and menopause change sleep, mood, weight, and intimacy, and being told your labs are fine doesn’t make any of that less real.

Look into hormone health →Jennifer

I want to look as good as I feel.

Refreshed, rested, still unmistakably you. Injectables, skin, and the kind of restraint that keeps people guessing what changed.

Your care team

Two providers, and a practice built around the whole picture.

Dr. Spiegel and Jennifer Gularson each bring their own training and focus, and they work through cases together. Whichever one you start with, you get their combined thinking on what is going on and what to do about it.

Neil Spiegel, DO, MBA

Board-certified Physical Medicine & Rehabilitation and Board-certified Anti-aging, Regenerative, & Functional Medicine

Thirty-five years in, and he still opens with what else is going on.

Dr. Spiegel is an osteopathic physician trained in physical medicine and rehabilitation, functional medicine, and regenerative care. He treats the person rather than the spot on the chart, which is why a knee complaint can turn into a conversation about your sleep, your gut, and the way you’ve been compensating for two years without noticing. Hands-on osteopathic treatment, advanced diagnostics, and regenerative options for people who’ve been told surgery is the only thing left.

Jennifer Gularson, PA-C, IFMCP

Functional & Aesthetic Medicine · Bioidentical Hormone Replacement

Women get told their labs are fine. Jennifer keeps looking.

Jennifer brings over 20 years of patient-centered clinical experience to the practice, with a deeply personalized, whole-person approach to care. Her goal is simple: to help patients look as good as they feel and feel as good as they look.

Grounded in Functional Medicine, Jennifer blends conventional and integrative care while looking beyond symptoms to understand the factors that may be influencing a patient’s health, including lifestyle, genetics, environment, emotional well-being, and relationships. This allows her to create individualized treatment plans designed around the person, not just the condition.

Our approach

Your symptoms are probably talking to each other.

Pain wrecks sleep. Hormone and metabolic changes move your mood, your weight, and how fast you recover. We look at those pieces together and use real diagnostics to decide what comes next, rather than treating each one like it showed up on its own.

ONE

We take the whole history

Everything you’ve already tried, what helped, what didn’t, and what nobody has asked you about yet.

TWO

We test past the standard panel

Normal is a wide range, and a result sitting inside it can still be wrong for you. We look at the full picture before we call anything fine.

THREE

You leave with a plan you understand

Written out, in order, with the reasoning attached, so you’re not guessing about the next three months.

What we do

Care that connects the dots.

Regenerative medicine

Treatments built to support the way your body already heals, so you can move without bracing for it. For people weighing their options before surgery.

Explore options beyond surgery →

Pain & physical medicine

Rather than treating only the painful spot, we look at how nerves, muscles, joints, and movement are contributing to what you feel.

Understand what is driving your pain →

Hormones & functional medicine

Bioidentical hormone replacement, functional testing, gut and metabolic work, and a plan for the energy and clarity you’ve been missing.

See what your body is telling you →

Aesthetics & skin

Injectables, microneedling, PRP, and medical-grade skincare, done with enough restraint that you still look like you, only rested.

What our patients say on Google.

Every review below was left by a patient on our Google Business profile.

★★★★★

“After years of suffering with allergic reactions whose source could not be identified by traditional physicians, I found Dr. Spiegel who analyzed my health history and critically examined my symptoms. The result was an accurate diagnosis and a treatment plan that has kept my symptoms at bay for the past 10 years.”

Tracy D.

★★★★★

“I could not have recovered without Dr Spiegel and Jennifer Gularson from multiple work injuries, while saving money and time by avoiding ineffective treatments and testing. I can walk and breathe again and leave the house without planning out where the bathrooms are.”

Jordan

★★★★★

“Dr. Spiegel is very thorough in asking questions about what is going on in your life that might affect your health, and he does not jump to conclusions, but will order tests to determine what the root of the problem is.”
