Born in Regina, Saskatchewan, Canada, Kent Weare developed a love for ice hockey, football and technology. He attended the University of Regina where he obtained a Degree in Computer Science. After completing his undergrad degree, he spent time in India completing a Post Graduate diploma in Object Oriented Technology. He currently lives in Calgary, Alberta, Canada but remains a die-hard Saskatchewan Roughrider football fan. Kent began his career at a small Internet startup before taking on a junior roll with the Saskatchewan Government. Since then he has worked on projects for the Canadian Federal Government, a multi-national bank in the United States, Health Care projects in Eastern and Western Canada, and has spent the last five years employed by a large Electricity Distribution company in Calgary. Kent's current responsibilities involve managing a Microsoft Solutions team that supports BizTalk, Exchange, Office Communication Server (OCS) and System Center. During Kent's time at the Federal Government, he had an opportunity to participate in his first BizTalk project. Seven years later he is still "hooked" on BizTalk having worked with every BizTalk version released since. In 2008, Kent was awarded his first Microsoft MVP award for BizTalk Server. He continues to be active in the BizTalk community and recently received his fourth consecutive MVP award. Kent maintains an active blog at http://kentweare.blogspot.com and may be seen presenting BizTalk related material at local and international user groups. Richard Seroter is a solutions architect for an industry-leading biotechnology company, a Microsoft MVP for BizTalk Server, and a Microsoft Connected Systems Advisor. He has spent the majority of his career consulting with customers as they planned and implemented their enterprise software solutions. Richard worked first for two global IT consulting firms, which gave him exposure to a diverse range of industries, technologies, and business challenges. Richard then joined Microsoft as a SOA/BPM technology specialist where his sole objective was to educate and collaborate with customers as they considered, designed, and architected BizTalk solutions. One of those customers liked him enough to bring him onboard full time as an architect after they committed to using BizTalk Server as their enterprise service bus. Once the BizTalk environment was successfully established, Richard transitioned into a solutions architect role where he now helps identify enterprise best practices and applies good architectural principles to a wide set of IT initiatives. Richard maintains a semi-popular blog of his exploits, pitfalls, and musings with BizTalk Server and enterprise architecture at http://seroter.wordpress.com.
