About Us

Our Lady of Guadalupe Free Clinic started as a simple dream between two friends to reach out to those in need and provide medical care for a few people who were concerned about their health care.  Over the past years, OLGFC has grown and is currently serving the needs of the uninsured in southwestern Minnesota.  Our clinic is operating approximately every two-three months at the office of Worthington Chiropractic Center in Worthington, MN.   We also have an office located in Worthington which handles our appointment scheduling and follow-up care for weekly visits.

Working with the volunteers and patients of OLGFC has been wonderful for me.  One of the greatest pleasures in my work is being able to assist those people in my community who were unable to access health care.  The relationships and trust that is developing is incredible and grows with each clinic.

I have known Father Jim for almost 20 years.  When he moved to Worthington, he was impressed that many of his parishioners had little or no access to healthcare.  He asked me to come to Worthington to see for myself.  I did.  I saw a great need.  I also met a great community of people who continue to give to me as much or more than I give to them.

     Not long ago, a man asked me to describe in one word the OLG Free Clinic.  The first word that came to my mind was CORAZON, or HEART.  I see the heart as the center of life and the place of ultimate understanding.  Love has the spiritual power that truly heals, liberates and changes people.

    The beginning of OLG Free Clinic is a love story of two friends who fell in love with the immigrant and the materially poor and welcomed every opportunity to enter into their lives and truly become one of them.  Gradually we became incarnated into this culture as we experienced a gradual transformation of the Corazon Imigrante y Pobre into our own body and soul.  

    We saw in these communities of people a God infused wisdom and clarity that emerged from the radical simplicity of their lives, and their daily suffering and total dependence on God.    Thus was born the Our Lady of Guadalupe Free Clinic.

It is with great joy that I share my time and talents with OLGFC.  What started as an attempt to serve and bless the poor and marginalized in my community, has turned into one of the great blessing in MY life.  The warmth and love I feel each time I am with the staff, volunteers and patients of OLGFC is overwhelming!  I am so grateful to the many people who have brought this much needed clinic to Worthington!

I became involved in OLGFC because I saw the need for counseling among individuals, couples, and families in the community.  A mental health component was added to the services offered at OLGFC because often times patients need to talk to someone about their life situation and challenges.  Every person living in a community is important and their needs matter - regardless of where they come from and how they got here.  Patient centered quality health care and counseling services is for all of us.

As an anthropologist, I have lived and worked with rural and indigenous peoples in Latin America and with immigrants and refugees in the United States.  My volunteer work and research with migrant workers and community health clinics across Minnesota has made me aware of the health inequities in our communities.  New immigrants and other vulnerable populations face obstacles to gain access to affordable healthcare.  I hope that my work with OLGFC makes a difference to effect change in our commmunities and take action against a cycle of poverty and disease.

I had the opportunity to be a part of the birth of OLG Free Clinic.  As a pastor we visited homes and encountered the harsh reality of people without health insurance.  OLGFC is a ray of hope and is a great blessing in the midst of physical and emotional pain.  I will continue to support this clinic that has brought much relief and rest to many people.
