Hammond Knoll’s Story

Local entrepreneur Ed Cartozian started cleaning oriental and area rugs in Tacoma in the 1930s. After WWII, the cleaning company moved to the present location on South G St. in Tacoma. In the early 1950′s, Ed began selling the newly popular broadloom carpeting (known today as wall-to-wall) and sold the cleaning business to two of his employees with the last names of Hammond and Knoll.

In 1987, Matt O’Haleck bought the local carpet store and building from owner Ed Cartozian. In its first year under new ownership, revenue increased 400 percent. The business has continued to grow 15 times larger since 1987, expanding from three employees to thirty. Today, Hammond Knoll continues its tradition of excellent service established by its founders.

Hammond Knoll’s people and workmanship are the keys to our pride and success. Employees strive to provide the best cleaning and service to our valued customers. By taking the time to learn and relearn, we keep abreast of new fabrics, carpet fibers, and cleaning techniques – which has made us the area’s best problem-solvers.

Marissa has a soft spot for pets, prior to working with HammondKnoll she managed a Petco.  She is a proud momma of a very small but very loud, full-of-herself Chihuahua and Min Pin mix.


There is a good chance you will talk with Lydia on the phone as she is part of our fantastic front desk team, and if you do, you are lucky because she is super sweet.

When Lydia is not working you can find her all cozied up with a book in her hand.  If you are a reader yourself you can ask her for the list she has built since being shut down with Covid.

While Lydia is reading she most likely has one or both of her dogs at her feet- Bagles the Beagle or Pepper the rat Terrier, Corgi mix (she says the only way you can tell Pepper is a Corgi is by her little butt!

He also enjoys rock hunting and fishing when he can grab a few minutes for himself.


Trevon brings a big smile to the pick-up and delivery team as well as one of the team members that does an amazing job cleaning your area rugs.

When Trevon is not driving the truck, he spends time outside working out as well as he enjoys going to the gym, one would say he is a bit of a “workout” freak.

Before working for HK, Trevon worked at Quality Stitching doing embroidery and screen printing, as a matter of fact, he in the past was the person to do our HammondKnoll shirts!
