Tell us about yourself


I am the Safety Manager and Medical Laser Safety Officer (MLSO) for the University of California at San Francisco (UCSF) Medical Center and Benioff Children’s Hospital; my name is Veronica Villalon and I have been a certified MLSO since 2011.

I completed both my B.S. in Chemistry and B.S. in Biology at UC Irvine (UCI) and studied synthetic organic chemistry for my Ph.D. at UC Santa Barbara (UCSB).  My first research project working with lasers was as an undergraduate at the Beckman Laser Institute (BLI) at UCI studying treatment of endometriosis using photodynamic therapy (PDT).

I have worked with lasers for over a decade and now oversee program compliance with Laser Safety across UCSF Health.  By becoming the MLSO for our institution, I am able to help UCSF meet the accreditation standards necessary to maintain patient care operations and provide the best health care.

I enjoy being the MLSO for UCSF Health and being involved in regulatory compliance.  I have the privilege of working with competent, knowledgeable, proactive professionals who are also passionate about staff, patient and visitor safety when it comes to lasers.  MLSOs today continue to be challenged by the ever-changing assortment of possible laser applications and rely heavily on department-specific Laser Safety Leads (LSLs) to assist with overall department laser safety program compliance.

Without a doubt, becoming certified as an MLSO has been beneficial for both the health care institution and for me as an individual.  Regulatory inspectors, leadership, colleagues and technical professionals recognize those who achieve certification are credible, knowledgeable and perform ethically in their field of expertise.  Should you wish to connect with me regarding my experience as an MLSO, please contact me at

Tell us about yourself

My name is Wendy Woehr Terrenoire. I have my MS in Radiological Science from the University of Lowell, Lowell, MA and my BS in Radiological Science from Manhattan College, Riverdale, NY.

I work at the Durham VA Medical Center in Durham, NC.

When did you start working with lasers?

I started working in laser safety at Duke University, Durham, NC in 2008 under Ben Edwards.

How did you become the LSO?

In 2012 I became the Laser Safety Officer at Duke. I attended a weeklong LIA course and obtained my CLSO certification.

Do you like being the LSO? What do you feel are the LSO’s challenges today?

I love being the LSO. Coming from the health physics world, I discovered that as I learned more about lasers, my job became more interesting and challenging. When I was LSO at Duke the program was huge, with hundreds of research lasers and just under 100 medical lasers, and growing each month. I had a great laser team to help cover the safety for this program. The biggest challenge was obtaining support from management for the installation of laser safety equipment.

In 2016, I left Duke for the job as Radiation Safety Officer at the Durham VA Medical Center. At the VA, I am also the Laser Safety Officer. The laser program is smaller but still has its challenges. As the first CLSO at this VA, I have introduced many changes to the program that will improve the safety and treatment of our veterans.

How has becoming certified benefited you in your career?

Becoming certified has been a definite help. It helped me secure the LSO position at Duke, and was a bonus for securing the RSO position at the Durham VA. I highly recommend certification for anyone responsible for laser safety.
