Melissa Greenstein was born and raised in New York, and recieved both her Bachelor’s and Master’s in Mathematics Education at SUNY schools. She met her husband in high school, and after teaching 3 years in NY, and four very warm summers, they moved first to Florida, and then Whidbey Island, Washington, where she taught another 3+ years, and eventually Atsugi, Japan, all with the Navy. Whidbey Island, and all of Washington state, will always be a special place, with the stunning mountains, bald eagles that flew over the house, and the endless fields and bluffs overlooking the water where she walked the dog after teaching. Her two best accomplishments are her daughters, and being a mom taught her advocacy, donating in as many ways as you can, and that sometimes, the best thing to do is get out of the way.  After the Navy, her husband’s jobs took them from Massachusetts, to Virginia, back to Washington state, and finally here to St Louis, Missouri in 2013. Here, for the first time, they were able to  buy a piece of land bigger than a postage stamp, and enjoy the outdoors all the time, right at home! Melissa has two businesses, a small craft business and an extensive tutoring business for Math and ACT/SAT prep. She most recently was the Democratic nominee for MO State Rep District 101. She currently works with AccessMO on outreach, as well as National Women’s Political Caucus at the state and local levels on endorsements and is the Chair of the State Ambassador program. Melissa cares passionately about many issues, but kids and dogs always make the top of the list….and you know what kids and dogs need? Safe environments in which to live, grow and learn.

Sandy Rothschild came to St. Louis from a small town in New York in 1963 to attend Washington University, where he received a Liberal Arts degree in 1967 and an MBA in 1971. He managed his friend Steve Vossmeyer’s successful campaign for state representative in 1972 and was active in organizing other political and issue races for the next several years, with a high success rate (over 80%). In 1976 the St. Louis Home Builders Associate hired him to start their government affairs department. His work to eliminate inequitable assessment practices in St. Louis County led to new homeowners receiving reductions at the Board of Equalization, making new homes more affordable to approximately 25,000 homeowners, and winning Mr. Rothschild a consumer protection award from the National Association of Homebuilders. He next worked with homebuilder J. David Cassilly to strategize a lawsuit which the Missouri Supreme Court used to force the first statewide reassessment (Cassilly v. Riney). That decision led to property tax reform and a constitutional amendment. Mr. Rothschild went on to form Sandy Rothschild & Associates, Inc. in 1985. Over the next ten years, the firm won five unanimous cases in the Missouri Supreme Court, most significantly a change in the residential property definition, widening it to include all apartments and nursing homes. Mr. Rothschild holds the title of Missouri Growth Association (MGA) Executive Vice President Emeritus. MGA is a group of commercial property owners, managers, and developers that helped successfully oppose an MSD rate increase. That case was argued by the late Lewis Green, who then worked with Mr. Rothschild to organize a class-action lawsuit that resulted in the return of more than $30M of overcharges to MSD’s ratepayers (Ring et al. v. MSD). Since retiring, Mr. Rothschild has volunteered in various capacities at Washington University, including as a member of the Eliot Society and the Alumni Board of Governors.  One of his proudest achievements is his service on behalf of the Parkview subdivision, where he served as an Agent (and at sometimes President) on the subdivision’s governing body, the Parkview Agents.  His years of work to maintain green space and get an assessment increase passed resulted in a park being named in his honor (Rothschild Park). Mr. Rothschild and his wife Sue reside in Richmond Heights.
