Professional Services Company

“Afferion’s team and approach to our sale was an exact fit for us. Its full service support provided exactly what we needed to reduce the time required to close our transaction. Their help in planning and in the transition process was invaluable. I would highly recommend Drew Ferner and his team if you are considering selling your firm.”

Engineering Company

“For personal reasons I needed to quickly sell my Company. Afferion presented a number of interested parties and assisted in a timely purchase at favorable terms. I was most impressed the Afferion team had not only industry knowledge but also staff members who had started, built, and sold personally their own Engineering companies in the past. They approached my deal with knowledge gained from actually walking in my shoes.”
