OWNER / CHIEF OPERATIONS MANAGER – Aaron Johnson

AJ Owner Aaron Johnson is one of the owners of Castle and serves as Chief Operations Officer overseeing production and the sales and design teams. Aaron formerly owned Camelot Builders, LLC where he gained a deep understanding of how homes work and many years of experience remodeling older homes.

His years of experience and calm demeanor make him ideal to oversee Castle’s large group of employees and the 50-60 projects we typically have going at any one time. A special ability to multi-task and a willingness to almost live on his cell phone allows Aaron to manage a group of Project Managers and efficiently oversee several projects at the same time.

Aaron is an avid brewer of beer (and consumer) and has grown his own hops. In his spare time Aaron likes to canoe the boundary waters. Aaron is married to Betsy Reller Johnson, has three children in the Minneapolis Public School system, and lives in NE Minneapolis.

PROJECT MANAGER – Scott Neff

SNWith a vast amount of knowledge in structural framing in older homes and 15 years experience in the remodeling industry, Scott has gone from just being on the team, to leading the team as our newest Project Manager. Scott received a Bachelor of Arts in Anthropology at the Iowa State University. At home Scott enjoys spending time with his two children, who attend the Robbinsdale Spanish Emersion School, and cooking for his family. Now that Scott is in charge of projects and not necessarily doing the dirty work, he likes to fix things up around the house and family cabin when he can. One day Scott hopes to leave the remodeling world to become a hops farmer and brew his own beer.

PRODUCTION MANAGER – Travis Hansen

THTravis Hansen started his career in the field working with siding and window crews and then branched off on his own. As the owner of Equity Investments Travis bought, fixed up and sold 8 homes completing nearly all of the remodeling work himself. Through the years, he has dabbled in several trades and became pretty spectacular with his hands. He is a perfect fit for handling the wide variety of projects we receive in our special projects division. Travis resides in Friendly Fridley and has a 10 month old daughter. He enjoys ice fishing and hunting at his cabin whenever he gets a chance. It is rumored that Travis either had a mishap with superglue or he is balding and does not want anyone to know since he never takes off his green Wild hat.

PROJECT MANAGER – Dave Ross

DRBefore becoming a carpenter, Dave had a few funky jobs that included doing endangered species surveys in Oregon and building custom Harley Davidson motorcycles. Dave started as an entry level carpenter in the middle of January (not the best decision) for what was at the time one of the biggest new home builders in the Twin Cities. He worked in the remodeling division and became a foreman after four years and worked for that company for a total of eight years. Dave then started his own carpentry sub-contracting company, working mostly with companies specializing in fire, water and storm damage. Dave has been with Castle since April of 2013, originally as a carpenter and now as a Project Manager.

PROJECT MANAGER – Steve Carr

SC Before becoming a carpenter, Steve had a boring desk job that was sucking life out of him and turning his hair grey.  Steve loved working with his hands and completing remodeling projects at his NE Minneapolis home in his spare time and decided to take the plunge and enter a new industry.  After a year in the field of showing off his smarts and carpentry skills Steve was promoted to Project Manager.  Steve is passionate about sustainability and loves learning about new building science techniques and products. Steve has 3 children in elementary/middle school and enjoys spending time in the wilderness.

OFFICE MANAGER – Miriam Rothman

MRMiriam Rothman (“Mimi”) was born and raised in South Minneapolis. She loves the area so much that she bought a house in the same area of her childhood neighborhood. She continues to enjoy and appreciate the lakes, parks and trails she grew up around. As an adult, she also appreciates the many local establishments where she can enjoy an adult beverage and see a local band, or play her favorites on the jukebox with her friends and family.

After High School Graduation and some courses completed in college, she decided to immerse herself into full time employment. She began in customer service at a busy national landscaping company. Over the next 17 years, she advanced positions, evolved, learned and honed in on her strengths and skills in the administrative arena. Additionally, spending 5 years moonlighting at a comedy club added an edge and observational aptitude and (sometimes off-color) sense of humor.
