“Back in the 1980’s I was very fortunate to have had Alex McDonald as my journeyman when I served my apprenticeship at Alpha McDelta Engineering.   The work ethic that Alex instilled in me and the skills he taught me have been very been instrumental in the success of my business. Alex was a hard task master  who took exceptional pride in his work and expected nothing but the best from us at all times.
