Allow me to introduce myself to those of
you who don't already know me. My name is
Chrissy Cebollero, and I am the current President
of our chapter, and have been involved on the
board over the last 4 years. I currently work at
Lowell General Hospital, and have for the past 17
years. About a year ago I became an
Administrative Coordinators (nursing supervisor)
and for the 11 years prior had been a staff nurse in
the ICU. I am married (to a nurse), and we have 3
kids in 3 different schools who are involved in
more activities than I can list.
I have been thinking and thinking about a
theme for this year. If you follow the newsletters
sent out by AACN they always have a letter with
suggestions on how to apply the theme of the year
or examples of how it was applied. Last year was
DARE TO... and this year is STEP FORWARD...
I thought of combining the two but instead have
decided on BE INVOLVED!
I would like to challenge you to BE
INVOLVED in something important to you. It
can be something small like voicing your opinion
about changes on the unit where you work. It
could be something bigger like joining a
committee which could make practice changes
hospital wide. I would love to challenge anyone
of you to be involved at the board meetings, or to
help plan our next program. Your involvement
may not have anything to do with nursing, but
something else you are interested in.

One event you may start with is our fall
program... Bundles, Guidelines & Pearls: Sepsis,
PAD and ABCDE. The all day program is being
held on October 22 at the Westford Regency.
Program brochures are available for download on
the MVC AACN website (accessed through
AACN.org). We will be having our next board
meeting following the program for anyone
interested in joining us.
Another upcoming event is the 3 day
Regional Horizons Conference. This time the
venue is Portland, ME and is being held April 2,
3&4 2014. Flyers will be mailed after the New
Year. You can look at HORIZONS2014.org for
more information.
Lead through example and BE
INVOLVED in the process.
Thank you and looking forward to another great
year,
Chrissy Cebollero BSN RN CCRN

2013-14 AACN Theme
(Submitted by Ellen Stokinger – MVC Membership Chair)
In May of 2013 “Step Forward” was announced at NTI as the new theme for AACN. Each year the
incoming president of AACN presents a theme to carry forth in her year as president.
Last year’s theme of “Dare to” … leads into this years’ theme “Step Forward”. Think of your own
practice/ profession, many days as a patient advocate you have dared to step forward and say your gut
feeling and you have pushed for further testing or further observation of your patient. In the rush to make
beds available in ICU how often do patients get pressed to move on to step down units. Are you there to
step forward and say they are not ready yet? I am sure there are many more situations to which we can
carry this theme.
In 1985 the Merrimack Valley Chapter started with 20 members. Now there are 120 members and
growing each year. Please Step Forward and exercise your ability to show leadership traits. There are
opportunities in the chapter to join a committee, attend board meetings (the Oct. meeting is after the
program). Then once you are familiar with the board activities you can and should run for office. Many
chapter officers have transitioned from staff to management positions possibly because they have “dared
to” “step forward” “with confidence”.
P.S. membership dues age 55 years and five years are reduced to $59/year; Also Submit four members for
AACN renewal together and save $10 off each - see forms on AACN website.
Don’t forget to renew your annual Chapter membership! Go to the AACN.org website to
obtain a MVC application.
