Meet your Board of Directors

Hello!  I'm Sarah and I'm thrilled to be a founding member of the ACMP Ohio Chapter.  I joined ACMP Global in 2013. After attending my first conference in 2014 I joined the Chapter Formation Committee.  Spending time on that committee gave me insight into how exciting local chapters were and how much energy there was to create one here in Ohio.  

I got my introduction to Change Management while working on mergers and acquisitions in the casino industry.  I realized how emotional major changes could be for employees and dedicated myself to making those experiences better for all involved.  I received my Master's Organization Development in 2013 from Bowling Green State University and am a Senior Change Consultant at Sequent. 

Hey there, I attended my first ACMP Global Conference in 2015 and it left enough of an impression on me to help start an Ohio chapter! My specialty is communications and I added OCM activities when I joined Scotts. My career path includes stops at Chase, the City of Dublin and ThisWeek Community Newspapers (appropriate since I have a Journalism degree from The Ohio State University).

I have a passion for bringing the perspective of the end-user to help teams successfully deploy projects, training and communications.  (Also, Sarah says I have mad editing and math skills - and that I lead the way in teaching technology to this formation committee.)

Hi everyone!  When I heard that Sarah was looking for a few folks to help stand up an Ohio Chapter of ACMP, I jumped at the chance!  I am excited to be a founding member. Having a local chapter will be a great way to grow our profession, as well as connect and learn from other change management professionals right in our own backyard.

I came to change management after having over 20 years’ experience across a variety of HR disciplines ranging performance & talent management, training & development, and HR Business Partner/Operations.  My career path includes stops at The Ohio State University, Sarcom, Nationwide Insurance and Cardinal Health. Having a life-long passion for education and development, I was always naturally drawn to the people side of change.  Training, communication, helping people manage through difficult situations…these came naturally to me.  When I found out that there was actually a profession for this – change management – I was hooked!  I look forward to growing a vibrant change management community!

Hi, I’m Deb and I too, am excited to be a founding member of the ACMP Ohio Chapter!  I joined ACMP in 2015, attended the conference, met Sarah, Jillian, Sue, and Mike and was hooked!   I got my start in change management working on projects for a large international consumer products company.   I saw firsthand how stakeholder engagement, communication and training can impact the outcome of projects.  Now I live it every day and love it!  I received my PROSCI certification in 2014 and currently work in Change Management at Cardinal Health. 

Hello, I am Phil. My career in change management began in the early 1980’s while leading a large business reorganization project in the UK. I was struck by the huge impact that engaging people can have on individual emotions, group momentum and project success. That lesson learned at an early age, combined with a passion for people, shaped the rest of my career.  For the past thirty years I have been leading organizational initiatives across North America, in a variety of industries including manufacturing, financial services, healthcare, consumer products aerospace and utilities.

I am delighted to be part of such a dynamic group, and to help further the profession of change management.

Hi - I’m Stacy. I first learned about Change Management in the 1990’s and was lucky enough to see early thought leaders such as John Kotter speak. I had my first Change Management assignment in 1994 at Deloitte Consulting. Over the course of the past 20 years in the field, I have seen the demand for and expertise in Change Management grow exponentially. My business partner, Kate Nelson, and I felt so passionately about the importance of Change Management that we wrote two books about it (The Change Management Pocket Guide ©2005 and The Eight Constants of Change ©2008), launched Change Guides LLC in 2005, and created a Certification in Change Management Program. In fact, Change Guides is a Qualified Education Provider (QEP) for ACMP.

It’s been great to see the knowledge base and community continue to expand. I first attended the ACMP Conference in 2011 and it too has grown every year. I’m excited to be part of this next chapter of growth by contributing to the ACMP Ohio Chapter. I hope to see you at an upcoming event!

I stumbled into my Change Management career over 20 years ago.  I was a high school Social Studies teacher when I was introduced to a career opportunity at a large consulting company…and the rest is history.  After many years leading large ERP implementations, found myself joining a small, rapidly growing human performance agency, TiER1 Performance Solutions, in Cincinnati.   I’m currently a Managing Director at TiER1, responsible for leading our Change Management practice.  I love talking about change and how it impacts individuals, even in the largest organizations.  I’ve been a member of ACMP since 2013, and honored to be a new Ohio Chapter board member in 2016.

After many years in Project Management roles, it struck me one day that my passion for the people side of change was much stronger than the technical side of change. This realization occurred while working as a Transition Manager, receiving technical changes from project teams and working with Change Leaders to plan new roles and training for people in operations. At that time, in 2009, I decided to learn everything I could about change management and how to most effectively help people through change. 
I've been impressed with the ACMP Global conferences the past two years, and now what I'm looking for is a local chapter where change leaders can meet each other and share their stories. It's exciting to be a part of the initial board of directors to turn this dream into reality.
