CAMBRIDGE — On July 1, Dr. Henry V. Wagner Jr. will retire from his roll as superintendent of Dorchester County Public Schools.

According to a letter submitted to the Dorchester Banner by Dr. Wagner, he announced his retirement Thursday in an executive session before the regular monthly meeting of the school board.

“I make this decision because of compelling personal, family, and professional considerations and with a variety of mixed emotions,” Dr. Wagner’s letter states. “Simply stated, it is time for me to embark upon the next enterprises of my life and career.”

Dr. Wagner became DCPS superintendent in 2010 after serving as assistant superintendent since 2007. He was appointed to a four-year term in February 2014 that was meant to run through June 2018. He began working in public education in Maryland in 1974 at a school in Baltimore.

Dr. Wagner’s letter stated many of the accomplishments achieved during his tenure.

“I believe that, together, we have accomplished much on behalf of the children of Dorchester County over the last 10 years. Achievement, scholarship, and graduation rates are at historically high levels,” Dr. Wagner’s letter states. “We have advanced our Capital Improvement Plan significantly and insured the construction of the new North Dorchester High School, while safeguarding and even augmenting the resources of our county. ... Most importantly, we have created a systemic climate that offers a real chance to close those persisting achievement and opportunity gaps; there is no going back now on fulfilling this moral imperative!”

Dr. Wagner stated that in his final months as superintendent, he will continue to make decisions on behalf of Dorchester County students and will also work toward the “smoothest possible transition” for the next superintendent.
