SWAFS Activities: Regular Member since 1990, have served on the Professional Conduct Committee, co-hosted the 1993 and 1998 SWAFS Meetings at South Padre Island, TX

OBJECTIVE: SWAFS has been a very important professional organization in the development of Forensic Scientists, not only in the scientific aspect, but in the enrichment of ethical values. We as SWAFS members have always taken pride in these values. Although, we at SWAFS always talk about Ethics, we need to bring in this kind of workshops to our meetings. With the rapid changes in forensics, we need to re-emphasized “ETHICS” in our work place. If elected I would like to bring workshops on Ethics to our meetings. Older or new Forensic Scientist, we can all benefit from workshops like this.

Secondly we need to continue to provide the latest up to date training that is available to SWAFS members and it’s guests.

Thank you; and I hope to serve your organization, SWAFS.

“I am very honored to be nominated to run for a position on the Board of Directors. I am relatively new to the SWAFS, but I pledge I will work hard for the Association and do my very best to provide effective representation for the members, if elected. I have been very fortunate to have been associated with some very fine instructors of great skill and integrity, and they instilled in me a sense that it is important to ‘give back’ to the community, and I believe one excellent way to do this is by participating in and serving in our professional organizations. There are several outstanding candidates, so--PLEASE VOTE! Thank you very much for allowing me the opportunity to run for the Board.”

Criminialist
 
Pasadena Regional Crime Lab
Pasadena, Texas
I have been in Forensics for over twenty years. My fields of emphasis have been controlled substances, toxicology and breath testing. In that time, I believe I have carved out a reputation for competent work based on sound scientific principles. With that being said, our field has seen dramatic change over the past decade with the most relevant change still to come. I have not necessarily agreed with the direction the field has moved; however, I am prepared to weigh all viewpoints while serving on the board to make sure any recommendations are thoroughly vetted. If elected, I promise to reflect on the founders’ visions for the organization and act accordingly based on honesty, integrity and rational decision making.
