About Me

I have chosen to design this site to communicate some of my skills and abilities, rather than just be another digital copy of my resume. Which can still be downloaded from the site.

I will identify some of my signature competencies as well as some of the work I have performed in those areas. I will list a work history but only company name, title and time employed.

Most of the Silks and Abilities have been used across multiple organizations I have worked with. So rather than listing “redundant” items on my resume, I list them here. I also have a table of many of the items I have worked with; again, to keep from having a 4-7 page resume.

Honesty, Integrity and Trust

These are my core values and have been through my entire professional career, regardless of what position I held, I could be counted on to step up and complete whatever responsibility was assigned to me. Although difficult to express in writing, I have never held a position in which I did not advance with the organization, or have my roles and responsibilities dramatically increased.

Client Testimonials

  • I want to thank you again for getting my computer set up so quickly. It is working great and has all my old stuff in place where it should be. You are always quick to respond and have such a positive and professional attitude. I like what you say, every time you help someone, "Is there anything else I can do for you today?" You are a great role model to other staff. It is very refreshing keep up the great work.

  • Lonnie, at his best, is articulate, yet never condescending. He can command a room while speaking to everyone’s level of understanding. Lonnie is the epitome of customer service as he handles stressful situations with patience, respect and even a little humor. Whether in the role of a leader, co-worker, trouble-shooter or friend, Lonnie shines through with integrity and grace!

    Jayme Bandel-Gray

  • Much thanks to Lonnie in IT. There was a problem with my phone and computer, it was not able to be fixed over the phone so Lonnie took the time to drive here on Christmas Eve from IL to fix it. Since everything for admissions runs through my computer you know what a nightmare it was. So with Lonnies help I will get both my admits today !!!!! There really is a Santa Claus. LOL Merry Christmas to all.

    Mikel Drobac RN - Nurse Liaison

  • A big THANK YOU to each of you. The professionalism each of you demonstrated on Saturday did not go unnoticed by board members and other key staff. Your hard work made the Leadership Summit a big success. That would not have been possible without your dedication and commitment to excellence. Your team work is one that establishes the standard that others should strive towards.

    Renee Deevey - VP HR/IT

  • Tomorrow is my last day of employment at Lutheran Life Communities. Before I leave, I wanted to take the time to tell you how impressed I am with Lonnie Lehman. In my three months at LLC, I have had the pleasure to work with Lonnie on several projects and issues. Lonnie approached each challenge with such enthusiasm and professionalism. Even when the issues were particularly frustrating and difficult to diagnose Lonnie persisted with grace, and a welcome dose of humor, until he found a solution. He always came through and is very, very good at what he does!

    Patti Steele - Foundation Operations Manager

  • What I like about you at your best is how well rounded you are as a leader. You have great depth and expertise in your chosen subject matter (which varies on a multiple of subjects to begin with!), but in strong leadership fashion the first thing you always do is listen…well and intently.
