Understanding SI
What is Structural Integration?
Your body is held together by a continuous web of connective tissue called fascia. This tissue wraps every muscle, bone, organ, and nerve — and it's the primary reason why pain in one area so often originates somewhere else entirely.
Structural Integration (SI) works with this fascial system systematically — session by session — to release restrictions, rebalance the body's segments, and restore proper alignment along gravity's line. The result is not just pain relief, but a fundamentally different relationship with your body: better posture, easier movement, and lasting structural change.
SI was developed by Dr. Ida Rolf in the mid-20th century. Mark practices Anatomy Trains Structural Integration (ATSI), based on Tom Myers' updated understanding of fascial continuity — one of the most advanced and research-grounded approaches in the field.
Board-certified practitioner. Mark holds IASI Board Certification — the gold standard credential for structural integrators — and completed 750+ hours of post-graduate ATSI training. This level of specialization is rare.
Key concept: Fascia
Fascia is the connective tissue that surrounds and interpenetrates every structure in the body. When healthy, it's fluid and supple. When chronically stressed, injured, or restricted, it thickens, adheres, and limits movement — often in places far from where you feel the pain.
Conditions that respond well to SI:
Why it Matters
How Structural Integration changes everyday life
The goal isn't just a comfortable session. It's a body that works better for everything else you do.
Mornings feel different
The stiffness that greets you every morning isn't inevitable. When fascial restrictions are released, your tissue stays supple overnight — and you wake up with ease instead of dread.
You move without guarding
That unconscious way you've learned to hold yourself — avoiding the movement that hurts — dissolves when the source of pain is gone. Walking, bending, reaching become natural again.
Your posture holds itself
You stop having to think about sitting up straight. When your structure is balanced, good alignment isn't an effort — it's just how you are. And people start asking if you've grown taller.
Work is easier on your body
Hours at a desk, working on your feet, driving — whatever your daily work demands, your body meets it with less tension accumulation and less pain at the end of the day.
Activities come back
The hike you stopped doing. The yoga class you quit. The game you gave up. Clients consistently return to activities they'd written off as "not for them anymore" — often within weeks.
Energy returns
Holding structural tension is exhausting — most people don't realize how much until it's gone. When your body stops fighting gravity and itself, you have real energy back.
How SI Compares
Why other approaches give temporary relief
If you've tried massage, PT, or chiropractic and gotten results that don't last, it's not because those approaches failed. It's because they target different things.
| Approach | Primary Target | Duration of Effect | Session Model |
|---|---|---|---|
| Structural Integration (SI) | Fascial system — whole-body structure | Long-lasting to permanent | Planned series of sessions |
| Swedish / Relaxation Massage | Muscles — tension and relaxation | Temporary (hours to days) | Session by session |
| Physical Therapy | Muscles, joints, movement patterns | Variable — skill-dependent | Protocol-based |
| Chiropractic | Joint alignment | Variable — often requires maintenance | Ongoing adjustment |
| Neuromuscular Therapy (NMT) | Trigger points, nerve pathways | Good — addresses root patterns | Targeted series |
Your Options
Choosing the right series
Structural Integration produces the best results as a series — each session builds on the last. The right series length depends on your history, goals, and the complexity of your presentation.
Non-series
For a specific issue or injury. Focuses on one region or pattern. Good for targeted rehabilitation or maintenance.
Targeted Series
A short series that addresses the whole body systematically from feet to head. This series serves as an introduction to the work while also getting improvement.
Full ATSI Series
The complete Anatomy Trains series. The most comprehensive structural reorganization — recommended for complex or long-standing presentations.

Is SI Right for You?
Who benefits most
- People with chronic pain that hasn't responded to massage, PT, or chiropractic
- Those with significant postural imbalances — rounded shoulders, forward head, scoliosis, leg length discrepancy
- Athletes seeking improved movement efficiency and injury prevention
- Anyone recovering from injury with lasting compensation patterns
- People who feel "stuck" in a body that isn't working the way it should
- Those who've been told their pain is "just how it is" — and aren't willing to accept that
- Desk workers whose neck, shoulder, and upper back pain is structural
- People whose pain "moves around" or seems connected across body regions
What to Expect
Your first session
- Intake and assessment — detailed health history and postural evaluation before we begin. This takes time and it matters.
- Structural mapping — identifying the specific restrictions and compensation patterns in your body, not a generic treatment.
- Hands-on fascial work — systematic release of the tissue restrictions we've identified. Most clients describe it as purposeful, meaningful pressure — not painful.
- Movement integration — small guided movements during the session help your nervous system process and integrate the changes in real time.
- Post-session integration — your body continues to reorganize for 24–72 hours after each session. This is normal and part of the process.
A client's story
Lynn B. — chronic neck pain, SeattleMark is a miracle worker!
After 4 months of PT for a crick in my neck with minimal improvement, I was referred to Mark by a friend. After one session I felt significant improvement. After 3 sessions all neck pain was gone, mobility was back to normal and no recurrence since (~6 months).
Last week I hobbled into a session with a cane and soft brace due to sudden onset ankle pain related to a previous break. In one session I was so improved, I left the session and walked for 2 miles (with soft brace just in case). All pain resolved within a few days.
I'm beginning to understand the breadth of Mark's ability to help me with a range of physical restrictions, pain and tightness. I feel so fortunate to have found him and to know I have him as a resource "in my back pocket" for the inevitable physical issues to come. I also appreciate how quickly his interventions work. Thank you Mark!
