Pelvic Floor Therapy, Orthopedics, and Everything In Between
Cassidy's practice is built around one conviction: your whole body is involved in whatever you're dealing with. She works primarily in pelvic floor therapy but also takes orthopedic and neurological cases — because the skills transfer, and because narrowing in on one area often means missing what's actually driving the problem.
She uses a hands-on, manual approach in every session. Research supports what she's observed in the clinic: physical touch helps calm the nervous system, which in turn helps reduce pain and build the kind of trust that makes treatment work.
"There's something important about human touch. Research shows it can help downstream the nervous system — and that plays a real role in pain levels."
On top of traditional pelvic floor and manual therapy, Cassidy is certified in dry needling and visceral mobilization — two tools she integrates based on what a patient actually needs, not what fits neatly into a standard protocol.
Pelvic Floor Therapy in Hinsdale and the Western Suburbs
Cassidy trained through Herman and Wallace, one of the most respected pelvic floor therapy programs in the country. Patients come to her from Hinsdale, Oak Brook, Westmont, Burr Ridge, Downers Grove, La Grange, Clarendon Hills, and Darien — often after searching for specialized pelvic floor care closer to home and finding limited options.
Conditions she treats:
- Vaginismus and dyspareunia — painful intercourse and involuntary muscle tension addressed through internal soft tissue work and nervous system regulation
- Pelvic pain and endometriosis — including intervaginal icing to reduce inflammation and prepare tissue for manual therapy
- Hypermobility — building the muscle strength that eliminates the need for compensatory tension
- Menopause-related pelvic pain — identifying when symptoms are hormonal and coordinating with referring providers
- Urinary incontinence — urgency, leakage, and bladder control through targeted pelvic floor rehab
- Bowel dysfunction and constipation — treated through pelvic floor coordination and manual therapy
How She Treats
Cassidy's approach combines manual therapy, nervous system regulation, and movement-based rehabilitation. She matches the technique to the patient — not the other way around.
- Internal pelvic floor assessment and soft tissue release
- Dry needling for muscular tension and trigger points
- Visceral mobilization to address organ and fascial restrictions
- Intervaginal icing for inflammation reduction in endometriosis cases
- Nervous system downtraining through meditation and vagus nerve stimulation
- Strength and stability training, especially for hypermobility patients
She also knows when a technique isn't the right fit. Dry needling isn't appropriate for patients with needle phobia or a sensitized nervous system — it can spike rather than calm the nervous system in those cases. Cassidy reads each person's presentation and adjusts.
What to Expect
Cassidy's goal isn't to make patients dependent on PT. It's to send them home with a working knowledge of their own body — what exercises helped during a flare, which muscles to focus on, and how to pick back up when life gets busy.
"I want my patients to feel equipped and in charge of how they feel. That autonomy — being able to advocate for yourself — is a big part of what I'm working toward with everyone I see."
By the end of a course of treatment, patients are typically around 75 to 90 percent improved and equipped to maintain and build on that progress on their own.
Why Physical Therapy — and Why Pelvic Floor
Cassidy grew up watching her younger brother receive physical, occupational, and speech therapy through Early Intervention. She was 12 years older and would sit in and watch, fascinated by the full-body approach — how everything connected, and how that coordination drove real progress over time.
That early experience pointed her toward PT. When she got to school, she assumed she'd go into pediatrics. Then she discovered pelvic floor therapy and realized how much it overlapped with her passion for women's health — and how much unmet need existed in that space.
Her final clinical rotation was an elective in pelvic floor. She wasn't certain she'd love it. She did. Her clinical instructor trusted her to treat patients rather than just observe, and that experience shaped how she practices today.
She still takes orthopedic and neurological cases alongside her pelvic floor work, because those experiences make her a sharper clinician across the board. The body doesn't isolate its problems, and neither does she.

Cassidy primarily treats pelvic floor dysfunction — including vaginismus, dyspareunia, pelvic pain, endometriosis, urinary incontinence, and bowel issues — as well as orthopedic and neurological cases.
