Kerrigan & Holt is an outpatient physical therapy practice with two locations in Boulder County, Colorado. We treat shoulders, knees, hips, backs, concussions, and vestibular dysfunction — and we treat them by actually treating them: 55-minute one-on-one sessions with a Doctor of Physical Therapy, not 18 minutes ping-ponging between techs. Our patients average 4.2 grade-level improvements on functional outcome measures between intake and discharge, and 88% return to their sport, job, or activity at a better level than they arrived.
We're not a generalist clinic. Every specialty below is owned by a DPT with additional fellowship, residency, or board-certification in that area. If we can't treat your condition at the highest level — we'll say so at intake and refer you.

Every patient at Kerrigan & Holt completes validated outcome measures at intake, at week 4, and at discharge. The measures depend on the condition: LEFS for lower-extremity, QuickDASH for upper-extremity, NDI for neck, ODI for low-back, ABC for balance, VOMS for concussion. We publish our aggregate outcomes on the wall of every clinic and update them quarterly. Here are the numbers from Q3 2025 (1,840 discharged patients):
"Tore my ACL skiing at Eldora in January 2024. Dr. Holt saw me 72 hours after surgery with Dr. Patel at Boulder Ortho. At week 22 I passed every return-to-sport criterion and was back on snow in December. He was also the only person in the entire process who told me, on day one, how hard it was going to be and then helped me do it anyway."
"Four weeks of vestibular therapy with Dr. Aoife after a concussion I got in a bike accident on Baseline Rd. I came in unable to drive or read a screen for more than 10 minutes. I left fully cleared by my neurologist and back at work. Aoife gave me a written home program I still do two years later because it's the reason I'm ok."
"I gave up on my low back for six years until Mirela. First session she watched me walk and asked about my left hip — which had been the problem all along. Twelve sessions over ten weeks and I'm running again for the first time since 2018. I referred my husband, my father-in-law, and two co-workers."
Colorado is a direct-access state; you can book a PT evaluation without seeing your doctor first. Most commercial plans don't require a referral. We'll verify your benefits in under 24 hours and quote you your out-of-pocket cost before your first visit — no surprises. Initial evaluation: $145 cash; insurance billing available.
Because PT that works requires your therapist's attention for more than 6 minutes at a time. The industry standard — particularly at clinics owned by hospital systems or PE-backed chains — is 2-4 patients per therapist per hour, managed between aides and students. Those models collect more insurance dollars per therapist hour; they don't produce better outcomes. Our model costs us ~22% more to staff; it's why our contracted rate is slightly higher and our cash rate too. It's also why our visit counts are 40% lower than industry average and our outcomes are 16 percentage points above the FOTO benchmark.
Honest answer: we don't know at intake, but we can usually estimate within 2 visits. Averages by condition (our data Q3 2025): low back pain 6-9 visits; knee OA 8-12; post-op ACL 28-36 across 5 months; concussion/vestibular 4-6; rotator cuff repair 14-18; pelvic pain 8-14. We set a visit budget at your evaluation and re-check against outcomes every 4 visits. If we're not progressing, we change the plan or refer out — we will never keep you longer than you need.
Kaiser Permanente and some narrow HMOs require in-network PT. We're contracted with Kaiser as a specialty-referral provider for pelvic health and vestibular (specialties they don't offer in-house). For general ortho, Kaiser members typically start in the Kaiser PT department; we happily see Kaiser patients as out-of-network for sports performance assessments or second opinions. Cash rate applies; we provide superbills but Kaiser does not reimburse out-of-network PT.
Yes — we send weekly progress notes to every surgeon whose patient is in our care, and we'll call them directly if anything looks off. We work most frequently with: Boulder Orthopedic & Spine (Drs. Patel, Maclean, Brogan), Panorama Orthopedics (Drs. Kim, Okafor), Mapleton Hill Ortho, CU Sports Medicine, and Colorado Brain & Spine. If your surgeon wants a specific protocol, we follow it exactly; if they're open to our standard protocols, our outcomes tend to be better with more strength work than most post-op protocols prescribe.
Yes, offered by 7 of our 12 DPTs, all with FDN-1 or Spinal Manipulative Therapy certification and Colorado Board authorization. Dry needling is used for trigger-point release, chronic tendinopathy, and chronic pain — it is not acupuncture and we don't claim it is. Evidence for dry needling is strongest for short-term pain reduction combined with exercise; we use it that way. Add-on cost: $40 per session for cash patients, covered under CPT 20560/20561 for most PPO plans.
Often yes — and that's fine with us. At evaluation we'll tell you honestly whether you're likely to do well with 2-3 home visits and a written program, vs 8-12 in-clinic visits. Roughly 25% of our eval patients get a "do this at home for 6 weeks, come back if you're not better" plan. We'd rather you heal than collect billables.
