Most organizations don't need someone else to run their analytics — they need someone to tell them, plainly, what the numbers mean and what to do next. GMBS Consulting is an advisory practice: we hand your team a clear recommendation and the reasoning behind it, with the rigor of federal research and the directness of a trusted advisor.
Start a Conversation See How We AdviseYou have data. You have reports. You may even have dashboards. But somewhere between the SQL query and the boardroom, the insight gets lost — and decisions get made on instinct anyway.
Most firms respond by offering to build you more infrastructure. We think that's usually the wrong prescription. What you're missing isn't another tool — it's someone qualified to look at what you already have and tell you, plainly, what it means and what to do next.
GMBS Consulting is an advisory practice, not a build shop. We bring the kind of rigorous analytical discipline developed in federal research environments — where the stakes of being wrong are measured in public health, not just quarterly earnings — and use it to hand you a clear recommendation, not a project to manage.
"The goal is not more data. The goal is better decisions. Those are not the same thing — and confusing them is expensive. Our job isn't to run your analytics for you. It's to tell you what they mean and what to do next."
Every engagement ends the same way: a clear recommendation, delivered in writing, that your team implements. We advise; you and your staff execute — that division is by design, not a limitation. If we're not the right fit, we'll tell you that too, and point you toward someone who is.
A structured assessment of your current data infrastructure, reporting practices, and how analytics actually inform decisions. Delivered in 2–3 weeks as a written findings report that tells you exactly what to fix, in what order, and why — your team carries out the plan.
For a specific, high-stakes challenge — a predictive model, a risk framework, a data architecture decision — we design the approach, specify exactly how it should be built, and hand your team (or your engineers) a blueprint to execute. We advise on the build; we don't run it.
A monthly advisory relationship that puts a senior data scientist in your corner — without the overhead of a full-time hire. We tell you what your numbers mean, what decision they point to, and where your own analysts' work needs correcting — on demand.
Gregory M. Blumenthal, PhD is the Principal of GMBS Consulting, an advisory practice built on a simple premise: most organizations don't need someone to do the analytics for them — they need someone qualified to tell them, plainly, what to do about it. His career began not in boardrooms, but in laboratories — building predictive models of how toxic substances move through biological systems, for agencies that couldn't afford to be wrong.
That work — developing PBPK models for the US EPA, contributing to projects for the NIH, VA, and NASA — instilled a discipline that most business analysts never acquire: the habit of interrogating your own assumptions before your results become decisions.
He now applies that same rigor to the data problems that matter to organizations in healthcare, cybersecurity, nonprofit strategy, and beyond. He is also the co-author of the annual Memphis Poverty Fact Sheet, a resource that uses demographic data to drive policy and community understanding of poverty in the Mid-South.
He is based in Memphis, TN, and works with clients nationally and internationally.

An international cybersecurity firm had sophisticated threat detection capabilities but struggled to communicate risk levels to non-technical executive leadership and enterprise clients. Reporting was technically accurate but operationally useless.
GMBS redesigned the analytics framework to express threat data in business-impact terms — cost exposure, operational risk, and decision thresholds — rather than technical severity scores.
Co-authored an annual data resource that synthesizes census, economic, and demographic data to give policymakers, journalists, and community advocates a rigorous, accessible picture of poverty dynamics in Memphis and Shelby County.
The project requires not just analytical precision but the ability to communicate complex socioeconomic relationships to audiences with widely varying technical backgrounds.
Developed objective criteria for evaluating Physiologically Based Pharmacokinetic models used in federal risk assessments — analytical tools that inform how regulators determine safe exposure thresholds for toxic substances.
The work required building evaluation frameworks that were both scientifically rigorous and practically applicable across a wide range of model types and chemical classes.
A growing remote work platform needed to understand user behavior patterns, retention risk, and feature adoption across a geographically distributed international user base — but had no systematic approach to collecting or interpreting that data.
GMBS specified the analytical approach from the ground up — what to track, how to model retention risk, and what an executive dashboard needed to surface — and reviewed the platform's own engineering team's implementation against that plan at each stage.
The Memphis Poverty Fact Sheet is an annual publication co-authored by Dr. Blumenthal that uses rigorous demographic and economic analysis to document poverty dynamics in the Memphis metro area.
It is used by policymakers, nonprofit organizations, journalists, and community advocates as a primary reference for understanding — and responding to — economic hardship in one of America's most economically challenged cities.
This work reflects a core belief at GMBS Consulting: that the same analytical discipline that serves corporations and federal agencies can and should serve communities.
