Welcome to the Home Page of David Arnold

The buttons across the top of the page ("Department Home Page", "Canvas", "Webadvisor", "Optimath", and "David Arnold Home") are live links to the pages they represent. They are presented for convenience. In addition, the CR Logo in the top right corner is also a live link to the College of the Redwoods home page. Clicking the logo will take you to redwoods.edu.

I encourage you to visit the Department Home Page where you can find announcements of upcoming events and a wealth of information on department activities and programs at College of the Redwoods. Return frequently, as the site is constantly updated.
