為填補馬克霍根辭職所產生的領導人空缺，美國國家混凝土砌體協會（NCMA）董事局已委任羅伯特托馬斯為渡期臨臨時總裁。羅伯特托馬斯是協會工程研究副總裁，他已經在協會工作了18年。與計劃，為了追求職業上更好的發展，霍根離開了工作了三十多年NCMA，此間的最后10年他一直擔任總裁。
一個對五月的規劃會議確定了協會的主要目標，包括：
（一）擴大支持新興硬景觀市場;
（二）為可持久建筑定位混凝土砌筑產品;
（三）為擴大市場優先投資協會；
（四）通過改進與相關組織的伙伴關系來借助資源。
2008年NCMA主席比爾霍爾登說：“改善的機會一直都有，對此我們的協會一直積極追求” 。

Filling the vacancy in its lead staff position following the resignation of
Mark Hogan, the NCMA board of directors has appointed Robert Thomas, vice
president of engineering & research and 18-year association veteran, to fill
the role of president in an interim capacity. With plans to pursue other professional
interests, Hogan departs NCMA after more than three decades, serving the last 10
years as president.
A May planning session identified key objectives, including (a) expanding
support for emergent hardscape markets; (b) positioning concrete masonry
products for sustainable construction; (c) prioritizing association investments for
market expansion; and, (d) leveraging resources through improved partnerships
with related organizations. Says 2008 NCMA Chairman Bill Holden (Block-USA),
“There are always opportunities to improve, and the association is enthusiastically
pursuing [them].”
