About TDS


Transitional Data Services (TDS) is a leader in professional services for the Virtual Data Center with offerings including cloud migrations, data center migration and consolidation, network and infrastructure design, and technical operations.

TDS created proprietary software, TransitionManager, to empower our consultants and clients to inventory IT assets, visually display application dependencies, and create interactive run-books to execute transformation tasks collaboratively.

Our clients realize minimized risk, improved project efficiency and increased speed of transformation, while facilitating more predictable, on-going technical operations. TDS’s clients include Kayak.com, The University of Texas, Boston Red Sox, Cedars-Sinai Medical Center, and Liberty Mutual.

How TDS is Unique

Our capabilities are unique in three key ways:

  • TDS principals and staff have deep experience in all facets of IT. This includes strategy, architecture, implementation and ongoing operations – while it also spans applications development, enterprise systems, leading edge data center design plus a deep appreciation for facilities and operations.
  • We take pride in understanding the business needs and impact so we can make recommendations that best align with the short and long term requirements. TDS works with our clients to optimize decisions based on budget, resources and risk.
  • By acting without the bias typical of vendors and VARs, TDS recommends solutions based on true needs – not the latest trend or highest commission. We are agnostic to vendors and platforms in our advice and recommendations.

Our Perspective

Our founders, Mike Bullock and Craig Macfarlane, have served as senior technology executives at a number of Boston-area companies. As a result, they are very experienced working with technology vendors and, in particular, the conflicts of interest that can arise with reseller relationships.

From the time Mike and Craig launched TDS in 2002, it was clear they were building a very different type of technology services firm – one that would put clients’ interests above all others. A firm whose values, incentives, people practices, methods, business alliances, and fee sources were designed from the start to maximize clients’ interests.
