George, I hoped in vain someone more familiar with ntheorem answers.

\documentclass[12pt,oneside,openany]{memoir}
\usepackage[amsthm,thmmarks]{ntheorem}

\newtheorem{theorem}{Theorem}

\theoremsymbol{\textbullet}

\newtheorem{theoremnoproof}{Theorem}


\begin{document}
\begin{theorem}
This Theorem requires proof
\end{theorem}

\begin{proof}
Proof
\end{proof}

\begin{theoremnoproof}
This theorem requires no proof
\end{theoremnoproof}

\end{document}
