I enjoy the certification process, that is the primary reason that I have so many of them. Obviously, there are ongoing career benefits and I don't want to understate how important that can be. However, I just love the challenge of learning new things and the certification process is a great enabler. When you study for a particular certification, you have to learn and master content that you never really considered all the important. At least, you didn't think it was important until you found out that you will be judged by how much you understand it. After I gain that understanding, I am continually amazed how often I use it.

Project Management Professional (PMP) from the Project Management Institute
The most important globally-recognized and independently validated credential for project managers. I gained this certification back in 2010 and consider it one of the best training experiences I've ever had.

Professional Business Analyst (PMI-PBA) from the Project Management Institute
Highlights expertise in business analysis and spotlights a professionals ability to work effectively with stakeholders to define their business/stakeholder/solution requirements, facilitate shared understanding of the project among project stakeholders and drive successful business outcomes.

Agile Certified Practitioner (PMI-ACP) from the Project Management Institute
An extremely well rounded certification that covers multiple agile approaches such as SCRUM, XP, LEAN and Kanban. It’s the only agile certification that requires a combination of training, experience and an exam.

Certified ScrumMaster (CSM) from the Scrum Alliance
A Certified ScrumMaster® understands Scrum values, practices, and applications and provide a level of knowledge and expertise above and beyond that of typical project managers. CSMs act as "servant leaders," helping the rest of the Scrum team work together and learn the Scrum framework.
