My professor uses these really nice, written out, AND and IMPLIES, etc., symbols and I can't seem to figure out or find how he does it.

I would love to use them, rather than \wedge or \land.

Is it even possible, or did he probably create them himself (or have someone do it for him)?

This is just straight-forward text, using a small-caps font:

enter image description here

\documentclass{article}
\usepackage{mathptmx}% http://www.ctan.org/pkg/mathptmx
\newcommand{\prob}[1]{P(#1)}
\newcommand{\AND}{\mathbin{\textsc{and}}}
\newcommand{\IMPLIES}{\mathrel{\textsc{implies}}}
\begin{document}
\[
  [\prob{r} \AND \prob{s}] \IMPLIES \prob{\mathbf{c}(r,s)}
\]
\end{document}

For spacing purposes, define these as macros using the appropriate \mathrel and/or \mathbin. See What is the difference between \mathbin vs. \mathrel?
