WE ARE TMC GLOBAL
The Microsoft partner you will never outgrow.
Three Microsoft practices. One conviction. One continuous line.
TMC Global is the technology partner that never stops evolving, because staying relevant to the people we serve is the whole point. Three Microsoft practices spent decades building trust the hard way: one client, one go-live, one renewed contract at a time. In 2026, we brought that work together under one name, so nobody we serve ever has to start over with someone new.

One partner across your whole Microsoft environment.
We work across Dynamics 365 (Business Central, Sales, Customer Service, Field Service, Marketing), Microsoft 365, Copilot, Azure, and Power Platform. Our team has spent decades learning what actually makes a Microsoft environment work for the people using it, not just the people who bought it.
We believe in a straightforward approach: no surprises, no lock-in tactics, no overselling capabilities we don’t actually have. With nearly four decades of experience across manufacturing, distribution, healthcare, retail, supply chain, and hospitality, we bring both technical depth and a genuine understanding of how businesses actually run.
Three practices. One team. No handoffs.
In 2026, three of the most established names in Microsoft consulting came together to build TMC Global: TMC, The TM Group, and PowerApps911. Each one built real expertise independently, over decades. TMC and The TM Group bring the ERP and CRM depth. PowerApps911 brings the Power Platform and AI depth. Together, that’s one team covering ERP, CRM, Power Platform, Azure, and AI, with nothing handed off between them.
Separately, each practice was a center of excellence. Certifications, best practices, technical mastery. Together, TMC Global is something rarer: a center of value. One team that measures success by what a client’s business looks like years after go-live, and by how much value the investment keeps creating as the business grows.
Excellence is what we mastered. Value is what we deliver.







Meet Jennifer, our visionary leader, mentor, and much more!
Jennifer Harris founded TMC in 1987 and spent nearly four decades building it into one of the most tenured and respected firms in the Microsoft ERP and CRM ecosystem. In 2026, TMC, The TM Group, and PowerApps911 came together as TMC Global: three practices that had each built something real over decades, now operating as one. Jennifer led that convergence and serves as CEO of the combined organization.
Jennifer’s focus has always been on building what she calls the Microsoft Partner of the Future: a firm that stays closely aligned with where Microsoft’s platform is headed, invests ahead of the change, and builds teams that help clients navigate transformation with confidence instead of confusion.
Long before diversity and inclusion became industry talking points, Jennifer was building teams that intentionally blended early-career talent with seasoned professionals, creating a culture rooted in mentorship and shared accountability. That wasn’t a value TMC adopted. It’s how TMC, and now TMC Global, was built.
Through nearly four decades of change in this industry, Jennifer has led with the same clarity and long-term view. TMC Global is where that view is headed next.
It all started with two best friends…
Jennifer Harris has worked in the ERP market for over thirty years. Forming a consulting business with her best friend Brenda right after graduation, the two moved to California and worked hard to establish themselves as one of the longest-standing and highest-regarded partners in the industry. Her finance background, coupled with her unwavering focus on great customer satisfaction, helped form the basis of what TMC is today. She is committed to building lasting relationships and ensuring the optimum customer service.
That same commitment is what led to TMC Global. In 2026, TMC, The TM Group, and PowerApps911 came together as one organization: three practices that had each built something real over decades, now operating as one team across a client’s entire Microsoft environment. Jennifer led that convergence and serves as CEO of the combined organization, still guided by the belief that started it all: clients deserve a partner who sticks around long enough to actually know them.
Brenda Diener (1961–2011) was a founder and CEO of TMC. Brenda headed up the Business Development team at TMC, where she concentrated on developing new business relationships and fostering existing customer relationships. In her role, Ms. Diener oversaw sales, marketing, and strategic planning. She was also the primary contact for TMC’s strategic partnerships such as Microsoft. Her commitment to customer satisfaction explains TMC’s long-dedicated “family” of customers, many of whom have grown with TMC over the years.
It goes on as a family… the TMC Global Family!
Known as being an agile, creative and cool place to work, TMC Global is also a place where its partners and staff (in-person, remote and virtual) can feel at home. TMC’s personnel are highly-motivated to contribute to the company’s success as they take ownership in the work that they do – and it shows. And while TMC Global is staffed and structured as a Global Microsoft Partner, its people are valued as much as the products and services they provide.
Always forward thinking in its operations, TMC Global’s five-member executive board is 66% female and represented by a person of color. By emphasizing a diverse and inclusive family culture atmosphere, TMC remains accountable to its vision: “To help our customers stay ahead of the competition & to bring together people, data, and processes to create value.”
“The company culture is fantastic. You really feel like you’re part of a family and that each and every one of us matters. It’s a place where everyone supports and looks out for each other, and the level of care is genuine.” — Practice Manager
“The work always has ups and downs, when it is down, the manager and colleagues will come to me to provide their help. There is no blame game here, we work together as a real team to move fast and quickly.” — Application Consultant
