Sound familiar?

› A funder is asking for outcomes data you don't have a clean way to report.
› Your program has grown past the point where anecdotes are enough.
› You need an evaluation design before you apply for — or renew — a grant.
› Your data lives in spreadsheets across different staff, sites, or cohorts.
› You need results explained in plain language your board can actually use.

What you get

›Study & experimental design
›Sampling and power analysis
›Cleaning & data pipelines
›Multilevel & structural equation models
›Publication-ready figures
›Reproducible R code you keep
›Grant and IRB methods sections
›Plain-language findings for boards and funders

We had an unrealistically tight timeline, and Dr. Yel jumped in without hesitation — not only met the deadline, but delivered a little earlier than we anticipated. He took the time to understand the situation behind the data and the implications of every insight. We know who to go to for future work like this.

DASS did a fantastic job. They were patient, clear about the coding, and very responsive to my emails. They took the time to understand the overall goal before proceeding with each step. Highly recommend.
