PRESIDIO OF MONTEREY, Calif. - The Presidio of Monterey welcomed Command Sgt. Maj. Robert N. Londers as the garrison's new senior enlisted advisor during a change of responsibility ceremony at the Weckerling Center, Jan. 10. He replaces Command Sgt. Maj. Roberto Marshall who is retiring after 28 years of service."I want to say thank you to all of my former teammates, friends that I've served with and my mentors. I wouldn't be here today if it wasn't for them," said Londers. "Now it's time to reinvest their energies into this installation and this community."Londers joins the Presidio after serving as the senior enlisted advisor of the 102nd Signal Battalion in Landstuhl, Germany. Prior to his latest stint in Germany, his career has spanned the globe with assignments in the United States, Korea and Kuwait.Garrison Commander Col. Greg Ford, Marshall and Londers took part in the traditional passing of the unit colors - a symbolic transfer of responsibility between the two senior enlisted leaders."Today as always in our business is a bittersweet day," said Ford during the ceremony. "It is bitter because we see the departure of a phenomenal command sergeant major who has made a positive impact in everything he's done, but it is sweet because you welcome another equally phenomenal command sergeant major who is excited and ready to continue those efforts."Marshall steps into retirement after 28 years on active duty and 16 years at the highest enlisted rank of sergeant major, including his final three years at the Presidio of Monterey."The last 40 months have been very rewarding," said Marshall."Everybody from the garrison team will forever have a special place in my heart."The Presidio's new command sergeant major expressed his thanks for the warm reception he has received."You have given me the keys to the castle and I truly appreciate it," Londers said. "I'm humbled and blessed to have this opportunity to serve."
