What a great team working to build a fabulous farmstead! Next month we’ll take another photo and include @tanamanda , the project architect. She couldn’t be with us because she just finished building a human! (Remi born two weeks ago) @westendbuild @tributary_land_design @ellencassillyarchitects #ellencassillyarchitect #allfemaleteam

26 years ago I took a “How to start your business” class through the Center for entrepreneurial development. I had the good fortune to meet Michael Currin during the 11 week class. His goal was different from the rest of the students as we were all relatively young and wet behind the ears. Michael had been running his company Greenscapes for decades. When asked why he was in this class with all of us neophytes he said something that really stuck with me. “I’ve been doing this for a long time, and I really wanted to take a look at my business with fresh eyes, and I thought that being here with all of you would help.” 

After our @fitch_pediatric_rehab lunch from @jerseymikes Let’s get this important facility built.
