Complete Commercial Janitorial Services

"Our Business is Maintaining your Business"

Servicing CT, MA, and RI Businesses Since 1988 

It is with both happiness and sadness that I announce the retirement of two valued members of the COBM Team,
Deniz Galeano and Alba Mejia.

Deniz joined COBM in 1999 as a part-time office cleaner and was quickly promoted to his current position of Manager on our Special Services Division where he was responsible for overseeing our carpet cleaning, window cleaning, floor stripping and refinishing, water damage restoration, etc. Alba joined COBM in 2000 also as a part-time office cleaner and was promoted to work with Deniz in Special Services. The two of them have worked together for the past 20 years and were well known and requested by COBM clients across Connecticut and Massachusetts.

Together they have been an invaluable asset to COBM helping to grow our Special Services Division from 2 full-time employees to 20 full-time employees. I have valued and appreciated their dedication and loyalty over the years and their efforts in contributing to the growth of COBM. I, along with everyone at COBM wish them well in their future endeavors.

Also, at this time I am pleased to announce that Segundo Vilchez, a long-time employee under Deniz, has been promoted to Manager of Special Services.
