Welcome! You could manipulate the enumerate environment with enumitem to get something of that sort.

\documentclass{article}
\renewcommand*\familydefault{\sfdefault}%
\usepackage{enumitem}
\setlist[enumerate,1]{label = \large\bfseries\Roman*.,
                      ref   = \Roman*}
\setlist[enumerate,2]{nosep,left=-0.5ex,
    label = \large\bfseries\arabic{enumi}.\arabic*,
ref =\arabic{enumi}.\arabic*} 
\newcommand\PseudoSection[2][]{\item {\large\bfseries \MakeUppercase{#2}}\par}
\newcommand\PseudoSubSection[2][]{\item {\large\bfseries \MakeUppercase{#2}}\par}
\begin{document}
\begin{enumerate}
 \PseudoSection{Introduction}
 bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla
 bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla.

 something about koala bears.
 \PseudoSection{Topic A}
 \begin{enumerate}
  \PseudoSubSection{Subtopic 1}
   bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla
   bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla.
