Faculty & Staff


Program Director


Jane Dinsmore – BS, LP, NREMT-P

Jane Dinsmore, the Program Director for the PERCOMOnline, Inc. and PERCOM EMS Medical Education Consortium Programs, has been involved in EMS for over 30 years with most of that time as a Paramedic. She has been heavily involved in EMS education since 1993 and became a Coordinator and Program Director in 1995 for Mother Frances Hospital (now Christus Trinity Mother Frances Hospital). She has also been a Coordinator and Program Director for a time for Tyler Junior College and then for another online EMS Education program before building PERCOM. She has worked 911 systems for most of her career and was the Operations Director for two 911 rural services, building one of them from the ground up. She also flew for two years as a Flight Paramedic with Mother Frances Flight for Life.

Mrs. Dinsmore has been a “mover and shaker” in EMS Education. She, along with her mentor and teaching partner, William E. Gandy, JD, LP, built the very first online hybrid versions for EMT and Paramedic education in 1998 at Tyler Junior College. They were told that it “could not be done” but they managed to create it and get it approved by the state of Texas as the very first state to deliver EMS initial training through this method. Since that time, she has been the leader in EMS education online development and delivery methods, and PERCOM was the very first CAAHEP accredited online/hybrid program in the state of Texas as well as one of the first nationwide. Accrediting and licensing bodies, as well as other education programs, have continually had to strive to keep up with the trailblazing in the education field that she and her team have demonstrated over the years.

Jane holds a Bachelor’s Degree from the University of Texas Health Science Center at San Antonio in Emergency Medical Services, is a licensed and National Registry certified Paramedic, and is a certified EMS Education Coordinator for the state of Texas. She is married, has six grown children, and has helped to raise one of her six grandchildren.

EMS Instructor Course Instructor

Peggy Fonseca, EMT-P, MCP

Became an EMS volunteer in 1989 for a Rural Hospital Based EMS System and then a Paramedic in 1991 for the same service. I was too young to drive the ambulance due to insurance requirements so I spent a lot of time in the back of the box.  I worked at various private EMS services as well as level two trauma centers.  I then became an EMS Chief in 1996 for a rural EMS service.  Due to the shortage of Paramedics in the rural areas of South Texas, I decided to grow my own Paramedics.  I successfully taught a Paramedic class in 2008 resulting in an additional 4 Paramedics for my service. I retired in 2015 and went to work for an international EMS service as EMS Chief, building an EMS service on the Texas / Mexico border.  I then started my own Public Safety Consulting / Grant Writing / Emergency Plan Writing / Continuity of Operations Planning (COOP)business and have acquired over 1 million USD in grants for Fire, EMS, Law Enforcement, and Emergency Management.

I have been an EMS Instructor since 1994 and have taught in various theaters both locally and globally.
