Parting Words From Outgoing NAB Members

As the 2022-2025 National Advisory Board (NAB) says goodbye to several members who have completed their term, sentiments are shared. Exiting NAB members would like to share their bittersweet parting thoughts with all of you.

“I encourage all members to stay focused on continuous professional development, to keep learning, and to keep #AchievingHigherStandards.”

– Michael Miscoe, JD, CPC, CASCC, CUC, CCPC, CPCO, CPMA, CEMA, AAPC Fellow

“To say I have thoroughly enjoyed my tenure on AAPC’s NAB would be an understatement. It was a pleasure getting to know and network with my fellow board members as well as the executive leadership at AAPC. It has truly been one of the best experiences of my professional career.”

– Kiosha Forston, MASS, CPC, CRC, RHIA, CHTS-TR

“I never would have thought three years would go by so quickly! I am so thankful to have served on the NAB and to have created lifelong bonds with the group. Meeting and working with members will forever be dear to my heart. I know the members will be in great hands with the new board. I look forward to seeing the continued growth and opportunities the NAB brings to all members. Thank you AAPC for the opportunity and the life-long memory of my term.”

– Sherrie Anderson, MS, CPC, CPC-I, CPPM, AAPC Fellow

“Being a part of the NAB over these past three years has been a great experience. This is what I will take with me always: I am honored to have been chosen to serve our membership through supporting AAPC’s initiatives. I am thankful to have my voice heard during our brainstorming sessions, and I have appreciated getting to know other inspiring and empowering individuals. Most importantly, this opportunity has helped me discover a new vision for my life. I learned that I have a gift for bringing like-minded people together with curiosity and learning. This may be the end of my term with the NAB, but I certainly hope it is not the end of my journey serving AAPC membership.”

– Vanessa Moldovan, CPC, CPMA, CPPM, CPC-I

“‘Parting is such sweet sorrow’ has never rung truer to me than now. I am so honored to have been chosen to serve on the 2018-2021 NAB. I feel like I have a new family. I thoroughly enjoyed meeting and representing the wonderful members of AAPC. It has been great getting to know and work with AAPC leadership; they truly have the best interests of the membership at the forefront of their goals. I will miss serving in this capacity.”


“Four years ago, as I was contemplating applying to serve on AAPC’s NAB, I wondered what the commitment would entail and what I could add to an organization that has molded me throughout my professional development. What moves us forward is often what challenges us most. While the tasks that I was privileged to complete were all-encompassing, the reward was even greater, from networking at conferences and the bonding with some of the most accomplished people in our profession to the great depth of information that I gathered along this path and how it has encouraged my growth. My biggest gain is the relationships built with the team that I served alongside as we developed what was best for the good of this organization. The most precious resource that we have is one another.

As Jeff Olson wrote in his novel The Slight Edge, “Successful people do the things unsuccessful people are unwilling to do.”

– Dianne Estes, CPC, CPB, COC, CPMA
