I love this Thesis Theme. Its highly SEO optimized. There are many options to customize whatever you like. Adding Menu in Thesis Theme is very simple. You can even customize the look and position. See here how to how to insert an Additional Menu in Thesis Theme
By Default Thesis support Only one Navigational menu. But you can add another secondary menu. There are 2 ways to add another menu.
Add Secondary Menu to Thesis:
You need to copy the below code to your custom_function.php file.
1. Open custom_function.php
2. Copy the code and paste it there.
3. Save it.
Now Go to Dashboard>Appearance>Menus.
You will see a secondary menu options there just like as category primary navigation menu. See there “Your theme supports 2 menus. Select which menu appears in each location”. Drag and Drop pages or category just like as primary menu. its settings just like asthe Default Nav Menu settings.
Note: The Thesis nav menu will be deprecated in Thesis 2.0. Please switch to the WordPress nav menu system, and recreate your nav menu there.
Another way to Add Secondary Menu to Thesis:

Change the Link to your page link and give title. To style these menu you need to edit custom.css file. Change the color code as you prefer.
