Allen Tollefson | Facilities Management, 25 years
![Allen Tollefson](/sites/g/files/dgvnsk3426/files/styles/sf_medium_width/public/media/images/allen%20tollefson.png?itok=XfsGHgDG)
Allen Tollefson’s remarkable 25-year journey at UC Davis Facilities Management began when he joined as an assistant superintendent in 1999. He retired on July 1, as the Facilities leader of the largest UC campus in terms of acreage, keeping our 5,300 acres and 14.6 million square feet of campus facilities safe, clean and operable through severe winter storms, wildfire smoke events, COVID-19, Picnic Day and many perfect spring days.
As Allen embarks on a well-deserved retirement, he eagerly anticipates spending more time with his family, especially his grandchildren, and taking some trips to ski and attend IndyCar races in far-flung places. "Not getting up at 5 a.m. every morning to prep for work will be a welcome change," he shared with a smile.
Reflecting on his 25 years at UC Davis, Allen marveled at the remarkable transformations on campus, particularly around its physical expansion and technological advancements. “Yet amidst these changes, what I will miss most are the connections forged with individuals and the dynamic atmosphere that constantly evolves,” noted Allen. “My hope is that UC Davis and Facilities Management continue being recognized for leading in so many areas, taking care of its people, and delivering top-notch work.”
Leading campus facilities is no easy task, especially given the size and age of our campus and our limited financial resources. Despite these challenges, Allen was able to pivot every day to meet the needs of our many stakeholders and respond quickly to the most pressing and complex needs. Allen’s leadership ensured our facilities were always safe, sustainable and operational. He was 'on' 24/7 and always made UC Davis his focus and priority." – Clare Shinnerl, FOA Vice Chancellor

Alan Winchenbaugh | Admin IT, 36 years

He soon transitioned into a full-time role, accepting a position in the Financial Aid department and later moving to the Accounting and Finance office, where he became involved with campus financial reporting and information processing.
Although Alan has worked in off-campus offices since 1997, he has always appreciated UC Davis’ mission for higher education through his participation in campus events.
One of Alan's notable contributions during his tenure was his work on the fiscal close process. He maintained an automated system for generating entries for the central accounting office. This crucial project required a dedicated block of time each year to ensure a smooth financial year-end close.
In retirement, Alan plans to reduce his screen time and replace it with gardening and physical activities like biking and hiking.
The growth of campus over the last 36 years has made it a privilege to be employed at UC Davis." – Alan Winchenbaugh

Pravin Sharma | Supply Chain Management, 22 years
![At Bulk Mail Services, senior mail processor Pravin Sharma uses a new machine that automatically wraps a pallet full of bulk mail; the pallets can then be moved easily by pallet jack. Previously, employees moved bulk mail in carts that weighed 700 to 800 pounds each when fully loaded. Be Smart About Safety paid $14,425 for the pallet wrapper, which eliminated most of the manual labor involved in moving the carts. As a result, employees will experience less stress and strain to their backs, shoulders and leg](/sites/g/files/dgvnsk3426/files/styles/sf_medium_width/public/media/images/Pravin.png?itok=EVJENVCg)
Pravin's journey at UC Davis began with night shifts in Custodial Services. However, after his children were born, “and started needing help with homework!” Pravin jokes, he transitioned to a daytime role in Bulk Mail Services. He loved the atmosphere, diversity and prioritizing customers. He cherished the relationships with his coworkers, who became his work family. His colleagues fondly remember seeing his kids grow up and participate in “Bring Your Kids to Work Day.” Pravin also treasured the annual tradition of attending Picnic Day with his family, an event they eagerly anticipated and never missed.
In retirement, Pravin is excited to attend his daughter's wedding in Fiji. He plans to spend time improving his golf game and, with the extra time on his hands, looks forward to being with his family, including his golden retriever, Lucky, and embarking on new travel adventures.
There are many great stories to tell and I hope I’ve left an awesome impression on each of my customers, management, and coworkers. I will miss this place.” – Pravin Sharma

She then transitioned to supporting UC Davis Student Health and Counseling Services as a purchaser in Supply Chain Management.
All the teams and departments Jenny worked with and supported highly regarded her efforts to go above and beyond. “Whether she was offering guidance on complex tasks or lending a helping hand during challenging times, Jenny consistently proved herself to be an invaluable asset to our team," said Katarina Mitchel, business supervisor with FOA Business Partners.
In retirement, Jenny plans to pursue several interests, including cooking, gardening, traveling and continuing to learn English. She looks forward to embracing this new chapter with the same enthusiasm and dedication she brought to her career at UC Davis.

During retirement, Chris plans to pack up his RV and continue his journey around the United States. He is excited to spend more time with his seven grandkids and enjoy his favorite pastimes like golfing, fishing and biking.

Over the years, Dharandar worked on many important projects, including upgrading floors and assessing buildings. In 2008, he was selected to work on time studies for Custodial Services, a testament to his commitment and expertise.

Scott Arntzen graduated from UC Davis in 1993 and joined Design and Construction Management (DCM) in 1994, eventually rising to senior project manager.

Highlights of Scott's time at UC Davis include working on every utility operated and maintained by the university, such as award-winning exterior lighting projects and a state-of-the-art cage wash facility certified LEED Gold.
While working for UC Davis, Scott gained tremendous knowledge about systems and equipment that he believes would have been difficult to learn anywhere else. He will miss the camaraderie and collaboration on interesting and critical projects but feels it is time to step down and allow new talent to bring their energy and vision to the campus.
I am confident the gains and strides will continue to keep UC Davis in the forefront of energy efficiency while providing for world class research now and in the future. Go Ags!” – Scott Arntzen

- What's one of your happiest moments from your time at UC Davis?
Being able to assist the School of Veterinary Medicine with general support and improvements to their compensation program has been the highlight.

- Tell us more about rescuing German Shepherds, please.
- In retirement, Carl looks forward to living life by the seasons, angle of the sun, and condition of the sky, rather than by the clock. He plans to vacation and travel without a schedule.
