Bay Area Retrofit’s qualifications include many contributions to the field.  This is all because of the efforts of structural engineer Nels Roselund.   He spent his half century long career as a Historic Building Preservation Engineer and building code development, specializing in the seismic retrofit of old buildings.  Thankfully, over the past twenty five years he has been teaching  me everything he knows about residential seismic retrofit engineering free of charge.   This comes from his strong belief that engineering should be used for the good of humanity.  I will forever be in debt to him.

I believe I know more about seismic retrofit engineering, especially how to apply these principles to actual houses,  than any other engineer in the field, except Nels.   He also introduced me to the leading seismic engineers at universities and research labs in the country.  He is not only the best structural engineer I have ever met, but is also a fine human being who believed, and showed by example, that earthquake engineering should be used to protect the public. Much of the information on this website is my attempt to do just that.
