Electrical Construction
A native of Phoenix, I began my electrical journey as an apprentice working in construction, which I did for 5 years. Currently and for the past 7 years I have been working as a journeyman electrician maintaining and repairing critical infrastructure at multiple industrial wastewater facilities. The electrical field has been a blessing to me and my family and has also allowed me the ability to bless others.

In the last fourteen years I coordinated Community Health Education teams in the developing countries of post-communist Europe.
