A Message from our Principal

Dear Union Families,

It gives me great pleasure to welcome the students, families, and community of Union Elementary School, proud home of the Union Cougars!

I am honored and privileged to serve as the Principal of Union Elementary.  I'm entering my sixteenth year in public education and my fourth year in the Union Elementary School District.  I look forward to continued opportunities to build relationships among our Union Community, observing quality instruction, interacting with students daily to support their learning and happiness at our school, and building many opportunities for leadership and pride in what we do.  

Our Staff at Union Elementary are committed to meeting the individual needs of all students. Our endeavor is to engage all students every day in every way, maximize our instructional focus, and set high expectations for all students. We are committed to the implementation of effective, differentiated instructional strategies that will impact our students the most.  We will work continuously to provide you with feedback on what your child is doing well, areas to work on, and how you can support your child at home.  "Together, we will succeed!" 

I believe in a true open door policy so if you ever have any questions, ideas, or concerns I encourage you to come and talk to me about them. Also, feel free to email me mwelsh@uesd.org or call 623-215-7930.  Working together we can make Union Elementary a wonderful place for our students, parents, staff, and community.
