A born and bred Mid-Westerner, Michala Costello moved to the northeast 15 years ago and now fully embraces soft pretzels, Wegmans, trips to the shore, and Philadelphia Sports. Since 2007, her Realtor portfolio has developed exponentially, spanning the entire Philadelphia region into its surrounding suburbs. Licensed in both Pennsylvania and New Jersey, Michala launched her expertise into the ever-growing and desirable South Jersey market. She is best known for guiding her clients to make smooth life transitions between the city and the suburbs.

With a Bachelor’s Degree in Psychology and a Master of Business Administration, she is uniquely equipped to help her clients navigate the process of buying, selling and investing in real estate. Michala takes the time to educate her clients, so that they are empowered to make the best decisions.


Michala resides in Haddonfield, New Jersey with her family and rambunctious dog, Jetty.



Multi-award winning Realtor, Lori Cooper brings over a decade of experience to every real estate transaction. Her huge smile and outgoing personality always draws potential clients in, but it’s her steadfast commitment to help her clients find their place in the world with the least amount of stress possible, that seals the deal.

A graduate of Ithaca College, Lori brings both a highly educated and practical real-world experience to one of life’s more joyful transitions: buying and selling a home.

As an active contributor in her community, Lori participates in local Rotary activities that include community outreach and fundraising. She also served for many years as the Haddonfield High School Row Team “Crew Mom,” a task best described as a labor of love.

In her spare time, Lori loves to cook and spend quality time on the beach. Lori resides in Haddonfield with her husband Grant, two children and her dog Molly.


Known as the detailed-oriented rock, JoEllen Musselman serves on The Costello Group as the Transaction Manager. Helping every client navigate the process from contract signing to closing, she meticulously handles timelines, title and mortgage communications, township and city certifications and everything in between.


JoEllen spent her early childhood weekends at open houses and never missed an opportunity to pick up the free Real Estate magazines at the grocery store. Consistently optimistic, she finds purpose in helping clients make home ownership a reality. Prior to real estate, JoEllen worked in the hotel, banking, and finance industries, where she honed her commitment to delivering excellent service to every client, every time.


JoEllen loves reading, running, going to musicals, and weekend getaways (especially to NYC!). She has enjoyed coaching middle school track and cross country in Chestnut Hill. She and her husband reside in the Mt. Airy section of Philadelphia with their three children, a bonus child they host from China, a fish, a kitty, and a dog.
