In Waltham, there has been a general complacency about keeping the public properly informed. As a result, official notices are often only posted physically on a bulletin board and only haphazardly included on the city’s official website. Sean believes that the city should post all official notices, meeting agendas, and meeting minutes in an easily searchable and readily accessible format.

The city website itself has long been outdated, difficult to navigate, and not following best practices for accessibility. In early 2026, Sean created a petition to improve the website accessibility and bring it into compliance with the Americans with Disabilities Act requirements. Starting in mid-2026, the city has finally started to make minor website accessibility improvements. If elected Sean would seek to make it a top priority for all city departments to optimize their webpage designs, functionality, and content to better meet the needs of waltham residents, businesses, and visitors.

As a personal request to anyone with limited visibility or other accessibility concerns, if you find anything about this website that doesn’t meet accessibility best practices please use the contact form to let Sean know!

In many parts of Waltham, a city of over 60,000 residents, many high traffic and neighborhood streets are not lined with ADA compliant sidewalks. Where sidewalks do exist, they are often made of crumbling asphalt, missing appropriate curb cuts, or blocked by utility double poles and other obstructions that force even able-bodied pedestrians into lanes of traffic.

From personal experience moving into a property that was missing any sidewalk for many years, Sean also understands that many residential property owners in the more suburban parts of the city are not in control of the right-of-way where sidewalks belong. As such, Sean would also look into legislative options to prevent municipal officials from enforcing violations, fees, and other costs upon residential property owners where the municipality has failed to properly construct or maintain ADA compliant curbs and sidewalks in the right of way.

Sean’s approach to addressing affordable housing emphasizes reducing minimum parking requirements to lower construction costs and increase flexibility for architects, property developers, and urban planners. It also aims to increase flexibility for unrelated tenants and maximize the use of our existing housing.

Importantly, it excludes ineffective policies that fail to address the root causes of housing affordability issues or result in unintended consequences. Instead, by focusing our energy on implementing more effective strategies, we can move toward a more building a more inclusive and affordable community.

If you have innovative ideas to improve housing affordability, I welcome your input and look forward to working together to make Waltham more accessible for everyone.

In the Waltham 2023 municipal election, the city spent tens of thousands of dollars to staff polling places and run a municipal preliminary election to reduce city council at-large race from 13 to 12 candidates & reduce the mayoral race from 3 to 2 candidates ahead of the general election. This cost was borne by taxpayers even though 1 of the mayoral candidates had already dropped out of the race ahead of the preliminary election. Also, since the top 6 city council candidates were the same in the preliminary and general election results, it is clear that having 13 vs 12 city council candidates on the general election ballot did not make a significant difference.

If elected, Sean would advocate for abolishing the preliminary municipal election process and replacing it with an instant runoff ranked choice voting process in all future Waltham Municipal elections. This would both save the city money and improve the opportunity for each voter to have at least 1 candidate they support get elected to each office on the ballot.

With degrees in physics and climate change science, as well as over a dozen years working in renewable energy and utility companies, Sean is extremely familiar with these topics and would take all necessary legislative measures to ensure a smooth transition to a carbon-free utility grid and pollution-free transportation and heating.

Over the past decade, Massachusetts has passed several laws that promote a cleaner utility grid without properly accounting for the cost to utility rate payers. As AI-driven data centers pile on top of EVs and heat pumps in the race for grid capacity, it is time to revisit safe nuclear power, fix utility connection queue rules, simplify renewable energy incentive programs, and encourage local manufacturing of key energy and utility equipment that are not subject to the whims of each federal administration or international trade.

It is very likely that during the next legislative session the Federal Government whether judicially, legislatively, or via executive order may attempt to impose new nationwide restrictions on reproductive agency. Massachusetts needs to be proactive in defense of and prepared to move swiftly to avoid undue interference in the reproductive agency of its residents, including appropriate protections for families, communities, medical staff, and relevant supply chains.

While some look at reproductive agency purely as a “pro-life” or “pro-choice” issue (or about who can play on which sports team), as recent actions by other state governments have shown, it is so much more than that. The same experts, medication, and procedures that are used as contraceptives and to perform abortions are also necessary for safe sex, healthy pregnancies, and saving lives. If elected, Sean would work with other legislators and state agencies to safeguard reproductive agency for everyone in Massachusetts.
