I’ve been on the faculty at De Anza College in Cupertino, California, since April, 1988, first in Physical Education, then in Biological and Health Sciences as well.

I’m a Red Cross certified instructor, primarily in lifeguard training, swimming, first aid and CPR/AED. I am also a Lifeguard Instructor Trainer, CPR/AED Instructor Trainer and Water Safety Instructor Trainer.

I have been a member of the De Anza College Academic Senate Executive Committee since April 2012.

I’m proud to have been a lifeguard, lifeguard captain or in charge of the swim of 53 triathlons or open water swims.

I was retained as an expert witness in a near-drowning lawsuit. The good guys won.

I have been a volunteer with Yosemite National Park Preventative Search and Rescue since March 2014.

Some of the classes I teach:

I usually teach every level of swim class each year. One of my favorites is EBBRO 45328 MCLAREN HONDA MP4-30 GP NO.14 FERNANDO ALONSO 1 43 SCALE (P.E. 26A/ KNES 001A). It’s a class for VERY beginning swimmers – including people who have never been in a pool or are even afraid to get in a pool, as well as people who can swim some, but are not confident in deep water.

Health 57A Hlth 57A, First Aid for the Community, Home, Wilderness and Disasters, is a one-unit class that is offered at De Anza almost every quarter. You can get the Red Cross certification or just take the class to learn first aid. The class meets for only four sessions, not all quarter and is done before finals week.

See the De Anza website for registration information:

In early 2016 the server for the first De Anza College faculty websites was near failing and faculty were told to move their websites off of it. As I have the time I will finish fixing links to and within pages.

I am the webmaster for this website.

In late October 2006 the original De Anza College version of my faculty website, one of the first at De Anza, received its one millionth hit. April, 2008 it received its two millionth hit. In late 2009, the three millionth. In late 2010 it had four million hits, in late 2011 five million. In March 2016 the server was failing and I moved the faculty website here.
