Hello and welcome, my name is Thomas Fonseca and I am a Sonoma county native. I am a resident of Rohnert Park California where I live with with my lovely wife Cheryl and our two boys Peter and Grant. I am a professional web developer, if this is of interest to you then please visit the services page. I am also a: son, father, husband, brother, uncle, runner and certified arborist.

I am an avid runner and a member of the Empire Runners Club. The background image for this site is a photo I took at Annadel State Park in an area of the park known as False Lake Meadow. Annadel is one of my favorite places to run. You can download a trail map of Annadel in pdf format here.

Computer programming is a passion of mine and so is biology. After learning about trophic levels in biology class I decided to write a java program to simulate three trophic levels, feel free to interact with it. Collecting vintage mechanical watches is another passion of mine, please check out my watch collection gallery.

A collaborative, user-driven project for San Francisco Bay Area coastal resource managers and planners to anticipate sea level rise and storms. For this site I contracted with a graphic designer who created the overall graphic design and layout. I implemented the design in HTML and CSS.



A broad-scale, international program to detect trends and quantify habitat associations for Pacific Flyway shorebird populations. The home page includes a slideshow I wrote in Javascript. I also connected this site to a MySQL database for the data browsing feature.



Created as a collaborative effort of the California Landscape Conservation Cooperative. For this site I created a color pallet and seamlessly embedded two mapping applications. This site also features an ability to download all climate related models.



The site provides a means of exploring and contributing to an examination of California's at-risk bird species. Connected to a MySQL database to accept input via html forms and provide data summaries. It also features embedded maps displaying climate models.
