Terri Parton

Jacqueline Platero

My name Is Jacqueline (Jackie) Platero, I am from and live in To’Hajiilee Band of Navajos Community for the past fifty (50) years. I have been involved in my community’s political aspects as an advocate as well as a tribal leader from 3 terms served. I enjoy my leadership as an advocate for the Canoncito Band of Navajos Health Center, Inc. Board of Directors as a Chairperson and presently a Vice-Chairperson. I believe in the high quality of health care for the American Indians/Alaska Natives in all health disparities for birth to elderly.

The most valuable and important area of health care that I find important is to pamper your health with teachings, best practices, mental/psychological stability, spiritual beliefs and physical well-being. My passion to protect those individuals that are most vulnerable, susceptible and powerless to their surroundings and do not have the guidance or support from family.

In the years I was elected as a tribal leader (Vice-President) it was my determination to uphold advocacy to highest level for my Navajo Community of To’Hajiilee Navajo. To accomplish barriers for quality water, quality health care, quality education, improve roads, improve homesteads, engage in elderly care, engage in substance/alcohol abuse, advocate for expanding health facilities and improving economic growth. In the years of leadership, we were able to accomplish better water systems with quality water that will be coming from Albuquerque, NM. In the areas of health care as a health board advocate with the supports of CBNHC BOD we were funded to expand our health center. We are presently working on improving our Behavioral Health Program including traditional medicines and traditional ceremonies for cleansing as well as a traditional site. Many other developments are in the process of being constricted to provide more employment to the community of To’Hajiilee Navajo. We upscaled broadband service to 350+ houses so they can utilize virtual learning for schools they attend, tele-health to families and virtual health awareness with traditional story telling.

In my years of tribal leadership, health board member, Indian Education Parent Committee and mother of 10 (2 deceased) have accomplish many goals, certificates, awards and trainings. The certificates presented as a participant was suicide prevention, grant writing, outstanding parent engagement, emergency preparedness, strategic planning, substance/alcohol abuse prevention (8hrs) and others. I have been involved in many workshops on policies for improvements.

It is important to provide information to those that do not understand what health care services is provided to sustain and neutralize tribal communities with their health disparities. Providing accuracy on health care needs as a professional helps tribal communities improve and understand the need to make those changes or correction if needed. Moving forward in health care proper initiative of advocacy is a high demand especially in remote areas where advocacy is limited. It is important for the United States Government to understand those tribal communities that have health services due to lack of advocacy and lack of funding. The need to have each tribal communities have the utmost advocacy is a high demand and can make improvements that may minimize health disparities. Every tribal community needs quality health care in every component to ensure they are not restricted or limited due to funding. The need to fund these health disparities is very important to tribal communities and it is the responsibility of each advocate to sustain all funding to ensure exceptional quality health care.
