MEET THE TEAM
Jonathan Ehlke
Jonathan has been involved in the real estate and finance industries since 2002.
In 2013 Jonathan spent a year working at the Indiana Housing and Community Development Authority, where he cultivated a passion for equal housing opportunities. From 2014 on Jonathan has been creating affordable senior, workforce, special needs, integrated and 100% permanent supportive housing developments across three states.
To date, Jonathan has leveraged his passion to secure financing for over 1,250 housing units totaling $275 million in development.
Jonathan is a Member of the Indiana Affordable Housing Council and serves on the Finance Committee of Indianapolis Neighborhood Housing Partnerships. Previously Jonathan served on the board at Near East Area Renewal, Hear Indiana, Inc. and as an Advisory Board Member of Hamilton County Area Neighborhood Development.
Born with a profound hearing loss, Jonathan credits others with giving him the opportunities to succeed and devotes his life to lifting up others with a disadvantage.
Jonathan is married to Heidi, and their three daughters Evelyn, Lydia, and Juliet keep him young and happy.
Also the above photo is 10 years old, but Jonathan thinks he looks pretty much the same.
Danielle Welsch Massey
Danielle joined Gratus in 2023, drawn to the mission of neighborhood-centered development and working with a heart of gratitude. She leads projects from concept to completion, shaping ideas into successful developments and seeing them through funding, design, construction, and lease-up.
Prior to Gratus, Danielle worked in community development and local government, where she managed HUD grants and compliance for affordable housing initiatives. That background has proven invaluable in her work today, allowing her to navigate complex funding stacks. Since joining Gratus, she has secured funding for more than 330 affordable housing units.
Danielle holds a Master’s in Urban and Regional Planning from the University of Wisconsin–Madison and a Bachelor’s in Economics and Business Administration from the University of Northern Iowa (go Cats!).
Danielle is a Certified Tax Credit Compliance Professional and an alum of the Urban Land Institute’s Real Estate Diversity Initiative. She serves on the Membership Committee of the Indiana Women’s Affordable Housing Network and leads the Events Committee for the Iowa Women’s Affordable Housing Network.
Danielle lives in Des Moines, Iowa with her husband, Alex, and their son, Julian. Outside of work she enjoys gardening, cooking, and restoring their 120-year-old home to its former glory. Alex does not share her love of DIY and tends to disappear when she picks up a hammer or saw.
Erica Davis
Erica joined Gratus in 2024 to assist in the development process and provide compliance expertise.
Erica has been in the affordable housing industry since 2004, and holds many compliance designations. She has held both on-site management positions and corporate compliance positions, and looks forward to utilizing her knowledge and experience with Gratus.
Erica started her career as a housing contract renewal intern, and quickly realized affordable housing was her passion. Upon graduating from Ball State University, she worked on-site at a 576-unit tax credit apartment community, and then transitioned to the corporate side of compliance.
She has worked as the Compliance Director for a multi-state national company, overseeing 1800+ units, and she has also worked as an auditor with a large global company, specializing in first year compliance.
Outside of work, Erica enjoys reading and spending time with her husband, Eric, and their two daughters Aubrey and Emma.
