Hello Nick
Thanks for posting in the Lucidchart Community! You can adjust the layout of your org chart using by double clicking on one Org Chart shape. After you double-click on one of these shapes you should see this menu. From here click Layout to see a number of Layout options. You can also adjust the spacing in this menu.
You can also create an org chart using Group View creating a more compact Org Chart.

The chart will appear like so: 
You can also move individual Org Chart shapes to positions that better fit your chart's needs. If the layout options do not fit your needs I recommend moving the shapes individually to create two columns. You can also learn more about working with Org Charts in this article in Lucidchart's Help Center. Hope this helps! Please let me know if you have any other questions.
