Diagnostic Clarity across the Lifespan

Answers in Weeks, Not months

What We Assess

Our evaluation provides thorough, objective profiling of speech, language, cognitive-linguistic, auditory processing, visual-spatial, and social-pragmatic impairments. We identify underlying communication bottlenecks, assess developmental delays, and gather standardized behavioral data.

Your evaluation begins with an intake appointment to review your concerns and build a testing plan. Testing is then split into shorter sessions to keep you or your child comfortable and focused. Within 4 weeks of your final session, you'll receive a detailed report with clear next steps.

What to Expect

Your report comes with clear, prioritized recommendations tailored to your or your child's needs. We share it with your physician so they can authorize care quickly. From there, we connect you with trusted speech, occupational, physical, and behavioral therapy providers across Northern Colorado.

The Mission

At Lifespan Assessment Services, LLC our sole clinical focus is delivering precise, objective diagnostic evaluations and neuro-developmental testing for pediatric, adult, and geriatric clients. We do not provide ongoing therapy; instead, we serve as a specialized diagnostic hub. We partner closely with regional therapy clinics, private practices, and specialists across Northern Colorado to transition clients into targeted, specialized treatment programs based on our evaluation findings.

Lifespan Assessment Services, LLC was established to answer a vital clinical need across Northern Colorado: providing families, individuals, and referring physicians with clear, unbiased, and timely diagnostic testing. Currently, our region faces a critical shortage of qualified healthcare providers with the specialized training, credentials, and psychometric expertise required to administer comprehensive neuro-developmental, cognitive, and speech-language assessments. As a result, families routinely encounter regional hospital and clinic waitlists ranging from 6 to 18 months just to receive an initial evaluation—delaying crucial early intervention, medical care, and specialized treatment.

Based in Greeley, Colorado, at Suites-on-18th, our clinic functions as an independent, accessible diagnostic hub. By focusing strictly on standardized testing and diagnostic profiling rather than ongoing therapy, we bypass traditional clinical bottlenecks. We deliver rapid, objective, gold-standard evaluations for clients of all ages—from early childhood through adulthood—furnishing families and primary care physicians with the precise clinical data needed to immediately authorize and initiate targeted care
