WDC-North America Staff


Regina Asmutis-Silvia, Executive Director - North America

Regina is our fearless leader. She has her USCG 100-ton near coastal Master's License and has been involved in whale conservation for over 20 years. Besides running the office, she is also responsible for a lot of our policy and advocacy work. She is a Massachusetts native, a walking encyclopedia of whale information, and obsessed with Keith Richards.

Missy Walker, Deputy Director - North America

Missy first became part of the whamily when she collaborated with WDC on an education program in 2013. She came on board in 2014 and oversees all of the fundraising and communications for North America. Missy loves all of her bird and squirrel friends that visit the feeder outside her office window and she teaches us all about vegetables that we never knew existed!


Colleen Weiler, Jessica Rekos Orca Fellow

Colleen first joined our whamily in 2013 as a Policy Intern. Since then, she has taken on the role of Jessica Rekos Orca Fellow and has spearheaded WDC-North America's orca conservation program.  Colleen works from her home on the West Coast (#bestcoast), is a master of whale puns, and is always one step ahead when it comes to policy affecting orcas.



Monica Pepe, Policy Manager - Conservation & Education

Monica has been in the WDC crew since 2009 when she started as a Field Research Intern. She came back the following year to volunteer and has been here ever since. She currently oversees WDC's three boater outreach programs. She is also a grammar queen and a Friends fanatic.

Michelle Collins, Program Manager - Science & Communications

Michelle started as a Field Research Intern with WDC in 2012. She couldn't get enough of whale conservation and came back in 2013 and hasn't left yet. She manages communications for WDC-North America, but always loves going on the boat to look for whales. She is proud of her midwest roots and has a freakishly good memory.

Sabrina 2016

Sabrina Braunlich, Program Associate - Communications & Outreach

Sabrina fell in love with WDC and marine life in 2016 when she started as a Field Research Intern. She couldn't stay away and joined us as the Program Assistant in 2017. She is now our rockstar Program Associate who manages all the fun on social media. She has experience as a radio DJ and has never heard a corny joke she didn't like.

Stephen McCloskey, Education Coordinator

Stephen joined the WDC crew in 2019 as the Program Assistant and then moved into his current role as Education Coordinator. Stephen brings his experience in environmental education and is watering the seeds of our education program to help it grow. Stephen brings a laid back style to the office and shows us every day why geology rocks.

Autumn Hanscom, Philanthropy Officer

Autumn joined us in early 2021. She brings her years of experience in grant management and grant writing to provide new opportunities for WDC. When she isn't knee-deep in grants, she can be found talking local policy as an elected representative for her town of Groton, CT and is a quesadilla connoisseur.

Ed Maheigan, Vice Chair - Finance and Audit

We couldn't function without our Superstar Volunteer Ed! Ed joined us in 2016 and has become a permanent fixture in our office, helping with managing our finances. Ed is an avid scuba diver and has been working on his cooking skills with help from his WDC crew.

Sarah McCormack

Sarah McCormack, Stranding Coordinator

Sarah joined the WDC team in 2021, excited to contribute to the conservation of seals, dolphins, and whales through the establishment of the Marine Animal Rescue and Response program. Though she enjoys life at sea level, you can find her snowboarding in the mountains in the wintertime or cheering on her beloved New York Mets from nosebleed seats in the summertime.

Lucie Baker, Office Manager

Lucie joined WDC in July of 2021. Since then, she has quickly been learning everything about marine mammals. She is a Plymouth-native and enjoys music, true crime podcasts, and horror movies when not overseeing office administration. She also is the one that sends out your whale adoptions!
