Meet the AHNA Board Members

Meet the members of the Arbor Hills Neighborhood Association Board! We meet on the second Tuesday of most months at 6:30. Interested in joining a meeting or joining the Board? Just let us know!


Ashley Gibson - President

I moved to the neighborhood in 2018, and a newsletter was sitting on the table when we toured the house. I knew then that if we picked this house, we’d not only become first-time homeowners – we’d also get to be a part of an amazing community. I joined the neighborhood association as newsletter editor before we even moved in, and I loved getting to know our neighbors in that capacity. Now, as President, I look forward to continuing to serve our neighborhood by building a sense of inclusion and community for all residents of Arbor Hills.

My husband Ean and I hope to see you around while we’re out walking with our son Arthur, born in July 2021, and our cocker spaniel Charlie.

To contact me or other board members, please email

When he’s not taking care of the lawn or walking their German Shepherd Greta, you can usually find him spending time on the lakes and in the woods of the Upper Midwest.

Jackie Bastyr-Cooper – Membership Coordinator

My husband and I bought our house on Heatherdell Lane back in 1998 a few months before our wedding. Our son was born in 2000 and our daughter in 2002. When the kids were little we attended the 4th of July parade and celebrations in the park. 

Both kids attended Leopold, Cherokee, and West. I was Leopold’s Parent Faculty Organization (PFO) president for 3 years and helped a lot with their annual events (especially the Timberwolf Trample – started by the parents of one of my son’s classmates). 

When my son was a freshman at West I became involved with the Madison West Athletic Booster Association (MWABA) as a liaison for the wrestling team. The following year I became part of the executive committee as the website editor. I am still involved with that group: updating the website (, managing their social media (Twitter: @west_athletic, Facebook: @MWABAWestBoosters), and communicating with parents/students via a dedicated Gmail account (also helping at events). 

With my kids gone at college, I have more free time and figured it would be fun to get more involved with this group.


Rebecca Koerschner – Communication Coordinator

My husband and I moved to Arbor Hills in November 2018. We spent the first year in our home mostly living out of boxes while we planned our wedding. We attended a couple of the food cart nights and got to know a few of our neighbors but I spent most of my free time planning and prepping for the wedding and honeymoon. We joined the neighborhood association, but didn’t have much time to dedicate outside of that. Even though I didn’t have much time, I always felt like I was a part of the neighborhood. Between a welcome from our block captain and the regular newsletters, we felt like a small piece of a larger whole. In the second year of living in Arbor Hills we had some new neighbors move in that didn’t have the same experience. They didn’t know about the AHNA, which made me feel like I needed to take action to make others feel welcome. I think there is a great opportunity for our neighborhood association to have better outreach to our new and younger neighbors, and I’m hoping that I can be a part of that!

Michael Horecki – Newsletter Editor

My wife and I moved to Arbor Hills this February 2020 right before COVID-19 shut everything down. Being new to the area, I wanted to find a way to get involved and meet folks in the area all while helping bring the community together!​

My day job is working for a large Communications Agency here in Madison! I lead a team of Public Relations professionals who work to secure media coverage for clients across the country. I have extensive experience writing articles like the ones that would go in the newsletter and enjoy finding interesting stories and sharing them!  

I’m looking forward to connecting with folks in the community and sharing the stories of our friends and neighbors! Especially during this time when people feel disconnected, I am eager to find ways to bring people together and celebrate the positive happenings in our area! 


Nicholas Griffiths – Block Captain Coordinator

I moved to Arbor Hills in spring of 2018. I love our street, Arbor Hills Park and the location of Arbor Hills in relation to Madison and the greater Madison area. I wanted to get involved to meet neighbors and create an inclusive neighborhood.


My professional experience includes over 17 years in Higher Education Administration at Northwestern University, Northwestern University’s Feinberg School of Medicine and the University of Wisconsin-Madison. My professional and personal experience will help with electronic communication during COVID.

I hope to create a more cohesive neighborhood environment, resulting in a cleaner, more welcoming, safer, and more neighborly Arbor Hills. I look forward to maintaining, and eventually increasing, lines of communication with block captains.
