About Diana & Dennis

QuickBooks & Computers

About Diana & Dennis Makes … we love to work together

When we met in May 1988, Dennis was the Co-Founder and President of Ophthalmic Imaging Systems (OIS).  Diana joined his business to temporarily fill in for the bookkeeper, but that assignment turned into 4.5 years of employment.  We worked together to help the company complete an IPO on NASDAQ in 1992.  Dennis remained in the company for another 6 years, while Diana retired and spent 5 years teaching herself  computers, web design, and Intuit QuickBooks software.  In 1997, Diana started the The Efficiency Experts.  In 2000, we left Sacramento and moved to Sahuarita, Arizona ~ just south of Tucson.  Dennis became the IT Specialist for The Efficiency Experts in 2002.

We both love computers and technology.   Diana’s focus is software training, with a strong emphasis on Intuit QuickBooks.  Dennis’ focus is on computer hardware including acquisition, troubleshooting, maintenance and repair.  Together we make a full-service team offering support for your PC computer and software programs.  We certainly have evolved through a lot of innovation and change in the computer industry since 1988, and we’re still curious and excited to grow with the ever-changing world of technology.

Our Clients

Our QuickBooks and Computer Clients

… mean everything to us.  We feel very blessed when they take the time to tell us how our QuickBooks and Computer services have helped them.

“Words cannot describe the professional work you do for our company.  Without The Efficiency Experts, we would be lost.  Every challenge our company has faced, whether it be QuickBooks or our computers, you have always found the solution.  I am very blessed to have Diana & Dennis as part of my team.”

Ivonne M., Port Devanning Services

“Sincere and heartfelt thanks, Efficiency Experts, for your invaluable help this week!  The rekindling of TV-SOS for my upcoming consulting project required a full rebuild of the financial, communication tools, and overall organization.  Diana and Dennis, you two put the pieces together so smoothly and capably that it just again proves your company name is spot on!  You and your knowledge are invaluable to anyone in need of the broad scope of services you provide to your client list daily.  With Gratitude”

Robb G, TV-S.O.S.

“Thank you, Dennis.  It is comforting to have someone like you to rely on for our computer needs.”

Clarke and Carol L. , Home Office

“I have worked with The Efficiency Experts for a number of years and recommend them without reservation. Dennis and Diana quickly resolve any technical or operational computer problems (always an emergency), address bookkeeping issues (think income tax) and respond to requests for business related administrative advice. They handle my unrepentant, perpetual computer illiteracy with patience and good humor. Good people – professional and very competent. I trust and depend on them.”

Bob M., Home Office

“May I be the first to congratulate you on the 20th anniversary of the Efficiency Experts.  What a huge accomplishment!  You’ve changed so many lives and businesses.  And it wasn’t just your expertise with QuickBooks and computers – it was your kindness and good humor no matter the circumstances.   Congratulations!”

Kathy W., Pacific Music

“Thank you for looking out for me the way you do.  You are both remarkable and wonderful.”

Terry F., Options & Resolutions

“I have known Diana for over 40 years and her husband, Dennis, for over 25 years.  They have been taking care of my computer needs for at least the last 20 years and have never had anything but great service and quality work.  I recommend them to anyone in need of a computer or service for your existing computer.  Tell them Carns sent you!”

Dennis C., Home office

“You are just great!”

“Dennis is truly such a wonderful person to work with! He is always helpful- no matter how complicated or simple our computer issues may be. Recently, we had a very challenging computer problem. Dennis worked tirelessly through the weekend and communicated with us every step of the way until we were up and running again on Monday. Being a small business we rely greatly on our computer to keep our business running smoothly. It is a great feeling to know if anything goes wrong we have such a highly skilled and equally enjoyable person to help us!”

“We really appreciate your dedication to our finances and your support of our mission.”

“From 1991-2005 I did everything, from invoices to payables to record keeping by hand.  I literally did not even have a computer.  So with a highly regarded recommendation to “get with the program” I called The Efficiency Experts. First thing we needed to do was to have Dennis set up our computers. Next step was to have Diana spend “endless” hours of teaching us how to work them.  Now here we are, 12 years and a few computers later, we can say that we know how to operate our PC’s.  Thank you, Dennis & Diana, for your unwavering commitment to be the best “computer nerds” ever!”

Judy & Eddie H., Vista Service Station Maintenance
“I appreciate the complimentary time.  Hopefully we will be working together a lot in the future.  You’re an awesome teacher!”
Tracy J., Independent Court Reporter

“Dennis, you remain on my active list for most prized tech person.”
