At Hoyle Tanner, we are fortunate to have expert leaders and innovative thinkers in every discipline. It is a big part of why clients trust us again and again, and hire us for various project services. Something we are extremely grateful for – and do not underestimate – is the value each team member brings. That includes our very special group of female engineers who focus on wastewater, stormwater, and drinking water quality services.

Affectionately known as the “WOW” Team within our hallways, Hoyle Tanner’s Women of Wastewater span generations and experience levels, with some just starting their careers and others making headlines with their years of expertise.

But it’s not just their experience levels that make them a group; it’s actually their willingness to teach and learn from one another that make this group of women truly an impressive team. It’s also a part of the reason some engineers join our firm – the chance to work and learn amongst brilliant women in a very male-dominated industry.

Below, these women feature a sentiment about why they love being part of WOW.

Kirstin DiPietro Worden corporate headshotKirstin DiPietro Worden, PE is a sought-out leader in our Vermont space, and a respected mentor to her WOW teammates. Her almost-30-years of experience include environmental engineering for water and wastewater treatment facilities, pump stations, sanitary collection systems, small-scale sewage disposal systems, and water transmission projects. Her experience also includes stormwater projects including design of stormwater treatment practices, development of flow restoration plans, and integrated water quality planning projects.

“As an idealistic teenager, I was drawn to environmental engineering with a passion to clean up the planet’s water systems. Almost 30 years later, I am living this dream through the work I do with Hoyle Tanner designing wastewater and stormwater treatment systems to keep our lakes and streams clean. When I started my career with Hoyle Tanner 26 years ago, there were few women in the field of engineering, and fewer still in the company, and mentorship with women was non-existent. Over the years as our representation in both the company and broader water resources sector has increased, there is a real sense of sorority and support for each other. As women, we face the double-edged sword of wanting a career and/or a family, and often have to prioritize one over the other. What has made the difference for me at Hoyle Tanner is that they worked with me wherever I was on that journey, giving me the support and commitment to find a balance and achieve both goals. As a senior female technical engineer at Hoyle Tanner, I am now in the position to provide that mentorship to younger female engineers, and I am looking forward to helping them navigate their way on their journey. I feel so fortunate to work with such a great group of women engineers at Hoyle Tanner  – we truly have a sisterhood here!”

“When I talk to people in and around the City [of Burlington, Vermont], and they find out that I am working on improving the water quality of Lake Champlain, they are all starved for information and want facts and ways that they can immediately help…. Yes, beaches close when there is an issue, which makes everyone sad and angry, but just telling someone that picking up pet waste can make a difference, seems to make them listen intently. Having people that care about what [the WOW team does] is really fun.”

Marisa DiBiaso corporated headshot with LinkedIn icon in cornerMarisa DiBiaso, PE has over 20 years of experience with an eclectic project background. She has done transportation engineering projects for municipal and state agencies, park rehabilitation projects, civil/site design layouts and drainage work. She has done engineering for stormwater design and has also been a lead engineer for the civil/site design of our wastewater projects.

“Some of my favorite projects have been large infrastructure and utility projects which include design and construction of stormwater, wastewater and water systems. Recently, I’ve been collaborating with our wastewater process team on wastewater treatment facility projects, and I really enjoy working with so many smart, team-oriented women to solve design challenges on complicated projects. In an industry where women engineers tend to be the minority, I’m really proud to belong to a company culture that breaks the mold.

Mallory Rakowski HeadshotMallory Rakowski graduated from Northern Arizona University in May 2022 with a bachelor’s in environmental engineering.

“As a young woman in the industry, although times have changed, there are still instances where I am the only, or one of few women in the room. Seeing women in leadership positions and knowing that I would be surrounded by a strong presence of amazing women is a big part of what drew me to Hoyle Tanner. Being able to see yourself in someone and having the opportunity to be mentored by other women on engineering work and career goals/paths has been invaluable. I am so grateful for every woman who makes up this team and for the opportunity to learn from them.”

“I think the WOW team is pretty special at Hoyle Tanner! I particularly like wastewater plants because although I’m a civil engineer and enjoy site, civil and structural projects, I get really jazzed up about wastewater treatment equipment, mechanical/electrical/plumbing (MEP) equipment and process controls. I’m learning something new with each project, and enjoy working with our subconsultants that do the design in these areas.”
