​Our Namesake

S. A. Parvin, "Parv", was my grandfather.  A man who stood for honesty, loyalty, friendship, integrity, and perseverance.  He always strived to earn and keep a good reputation by treating others fairly and with respect.  He always made you feel like the most important person in the room.  It is those same values that we aim to uphold within Parv Consulting.  

Our Vision


​Melissa Parvin completed her Master’s Degree in Clinical Exercise Physiology from Louisiana State University.  She instructed at LSU in the Kinesiology Department and worked at Pennington Biomedical Research Center as an exercise physiologist prior to becoming a stay-at-home mom.  She is committed to bookkeeping for Parv Process Consulting and Engineering, LLC.


He was an accomplished golfer and has been recognized in the Book of Golf for his many holes-in-one.​  He was a World War II B-17G pilot and flew several bombing missions over Germany before being shot down and captured as a POW.  After 13 months as a POW, he was freed by General Patton.  He was awarded a purple heart.  More details on his war experiences are available by request.


In God We Trust--quite simply, on the outside looking in, we chose likely the worst time in the last 30 years to start a engineering/consulting firm.  The decision was not made lightly, and it took a struggle of walking in faith vs. having the security of a paycheck.  In the midst of the worst downturn in over 30 years (2nd quarter 2016) we followed His leading and decided to voluntarily quit my job and start this endeavor.  Melissa said it best..."God's got this".  She was right.  God has been providing our needs and guiding us.  It hasn't been easy.  We're thankful and continue to say "In God We Trust", because we do.

To be a safe place for people to learn, apply their knowledge in a safe & practical way, and deliver value, excellence, and expertise to the engineering community.
