Michelle Hudacsko, chief of staff for Richmond Public Schools Superintendent Jason Kamras, has resigned.

In an email addressed to Mr. Kamras and the RPS School Board less than a week ago, Ms. Hudacsko announced her last day of employment with the school division would be Feb. 28.

“It has been a privilege serving RPS students, family and staff over the past five years,” she said in announcing her resignation. She cited accomplishments during her tenure, including navigating the school division through the COVID pandemic, facilities improvements, managing the budget, the collective bargaining agreement and more.

But Ms. Hudacsko was critical of the “hostile and toxic environment that some members of the RPS School Board have created and actively perpetuate on a daily basis . . .,” and said the students ultimately pay the price for the often adversarial interactions between some members of the School Board and Mr. Kamras.

In his daily digital communication addressed to the division, RPS Direct, Mr. Kamras announced Ms. Hudacsko’s departure on Tuesday.

“Michelle is quite simply one of the most impressive people I have ever met,” he said. “We have worked together for 12 years and I’m still constantly amazed by her work ethic, intellect, thoughtfulness, dedication, empathy and humanity.”

He said Ms. Hudacsko will be remembered for the “thousands and thousands of so-called little things” she did for people. “She showed us all what it truly means to #ServeWithLove.”

According to her LinkedIn profile, Ms. Hudacsko worked as the deputy chief for Washington, D.C., Public Schools with Mr. Kamras before joining RPS with him. She began her career working for several years as a schoolteacher in Weslaco, Texas, Washington, D.C., and Potomac, Md. before working for a couple of nonprofit organizations focused on education.

Ms. Hudacsko is one of several members to leave Mr. Kamras’s cabinet since the start of his administration. Others have included Tracy Epp, former chief academic officer; Alan Gonzalez, former chief operations officer; Darin Simmons Jr., former chief operating officer; two chief talent officers, Jennifer Bramble and Sandra Lee; and Harry Hughes, former chief schools officer. Various reasons were given for their departures, ranging from a taxing commute schedule to medical reasons.

With Ms. Hudacsko’s departure, Shadae Harris, chief engagement officer for RPS, is the only original cabinet member who remains in Mr. Kamras’ administration.
