Honoring Those Who Served 🇺🇸
To our veterans—
Your strength, your sacrifice, and your resilience do not go unseen.
But strength doesn’t mean carrying everything alone.
Many veterans live with: • PTSD
• Anxiety
• Depression
• Chronic pain from physical trauma
These experiences live in the nervous system… long after the moment has passed.
Through acupuncture and Structural Reintegration, we create a space where your body can finally begin to let go—
to shift out of survival mode and into healing.
Now accepting VA Community Care (VAAC)
You served for us.
Now it’s time for your body to be supported too.

🧠🌿 TRAUMA IS STORED IN THE BODY
Not all trauma is the same…
and not all acupuncture treatments for trauma are the same.
In Kiiko Matsumoto Style Acupuncture, we assess how trauma is held in the body, not just the mind.
Through palpation and reflex points, we can identify where the nervous system is stuck—and how to release it.
⚡ DIFFERENT TRAUMA PATTERNS = DIFFERENT POINTS
KID 27 → Shock, PTSD, hypervigilance
• Regulates breath + nervous system
• Common in patients who feel constantly “on edge”
KID 16 → Deep fear, core instability
• مرتبط with gut + survival center
• Often tied to early life trauma
KID 9 → Anxiety, overthinking
• Helps calm emotional overwhelm
• Supports deeper emotional integration
🧘‍♂️ THIS ISN’T JUST RELAXATION
Real trauma work is about: • Resetting the nervous system
• Releasing stored patterns
• Restoring safety in the body
There is no one-size-fits-all treatment.
Your body tells the story—we listen.
🌿 MY APPROACH
Structural Reintegration Acupuncture
• Nervous system regulation
• Deep muscular + structural release
• Trauma-informed care

There’s something most people don’t talk about when it comes to healing:
Not all progress feels comfortable.
When you’re dealing with something like severe cervical spinal stenosis,
the body has often been stuck in dysfunction for years.
Releasing that pattern—
restoring movement, decompressing tissue, reactivating nerve pathways—
can sometimes be intense.
But here’s the difference:
👉 There’s a purpose behind it.
👉 There’s precision behind it.
👉 And there’s experience guiding it.
I always tell my patients:
There’s a difference between harmful pain… and therapeutic discomfort.
One keeps you stuck.
The other moves you forward.
As a practitioner, my job is to:
Know where that line is
Communicate clearly
And have the confidence to guide you through it safely
Because on the other side of temporary discomfort…
is often real, lasting relief.
This is especially true with Structural Reintegration Acupuncture,
where we’re not just chasing symptoms—
we’re correcting the underlying dysfunction.
If you’ve tried everything and nothing has worked…
you may just need a different approach.

Why I Choose to Be a Solo Practitioner
In a world of high-volume clinics and fast-paced treatments… I chose a different path.
1. I’ve been there.
I’ve worked in high-volume settings—treating up to 9 patients at once and over 50 in a single day.
And while that model works for some… it never felt aligned with the level of care I know is possible.
Today, I limit myself to 2–3 patients at a time
so every person gets my full attention, precision, and presence.
2. I trust my work.
When you come in, you’re working directly with me—every time.
No hand-offs. No inconsistency.
Just focused, intentional care designed to get real results.
3. I genuinely love what I do.
This isn’t just a job for me.
I enjoy treating patients. I enjoy the process.
And that energy translates into the treatment itself.
4. This is a lifestyle—not a business model.
I’m not here to build a revolving-door clinic or profit off other practitioners.
If someone works out of my space, it’s simply because they’re renting it when I’m not there.
This practice is built on integrity, presence, and results.
If you’re looking for real, personalized care…
you’re in the right place.

We’ve come a long way since that first treatment—restoring movement after surgery where there was none at all.
For someone who has experienced that level of trauma, even the smallest return of movement can feel like a miracle. And with that comes something just as important: renewed belief in a full recovery.
A big part of healing is restoring that faith.
I take pride in making every patient feel comfortable, safe, cared for, and motivated throughout their journey. With decades of experience treating complex and challenging cases, I’ve become known as “the acupuncturist your acupuncturist goes to.”
You deserve to feel confident in who you choose to guide your healing.
Specializing in Structural Reintegration Acupuncture for: • Chronic pain
• Chronic disease
• Complex nervous system imbalances

I accept most major medical insurance as an in-network acupuncturist.

I offer membership rates for patients without insurance to make acupuncture affordable and easily accessible.

I am a Licensed and insured Doctor of Acupuncture in the State of New York.

I have twelve years of clinical experience.

For over a decade I’ve dedicated my life to the healing arts.
I am a licensed and insured Doctor of Acupuncture and Licensed Massage Therapist, and I have been in private practice since 2015 helping people recover from chronic pain, nervous system dysregulation, and structural imbalances in the body.
Over the years I noticed something important:
Many chronic conditions are not just “pain problems”…
they are nervous system problems.
Posture, injury, stress, and modern lifestyle habits can distort the structure of the body and place constant pressure on the nervous system — keeping people stuck in sympathetic dominance (fight or flight).
This realization led me to develop my own method:
Structural Reintegration Technique
A specialized approach that combines:
• Advanced acupuncture
• Intramuscular trigger point therapy
• Structural assessment
• Nervous system regulation
The goal is simple:
Restore the structural integrity of the body so the nervous system can finally relax and function the way it was designed to.
This work has helped many people struggling with:
• Chronic muscle tension
• Neck and back pain
• Postural distortion
• Stress and nervous system imbalance
• Persistent pain conditions that haven’t responded to other treatments
If you are looking for experienced, professional care, you are in good hands.

90-Minute Dry Needling + Therapeutic Massage
This is not a typical massage session.
This treatment combines clinical dry needling with deep therapeutic bodywork to release chronic muscle tension, deactivate trigger points, and restore mobility to the body.
Dry needling works by targeting tight muscle fibers and neurological trigger points, allowing the muscle to reset and relax.
Massage therapy then helps to:
• Improve circulation
• Flush metabolic waste from the tissue
• Restore range of motion
• Calm the nervous system
The combination creates a powerful therapeutic effect that many people describe as one of the most effective treatments they’ve ever experienced for chronic pain and muscle tightness.
This treatment is especially helpful for:
• Chronic neck and shoulder tension
• Low back pain
• Tight hips and glutes
• Athletic recovery
• Long-standing trigger points
