Andrea Oct 2014

Andrea Herzberg

"The women of SHARE were there for me 17 years ago when I was diagnosed with late-stage ovarian cancer. I am lucky to have done well, partly because of prolonged treatment and partly because a friend and fellow survivor at my doctor's office led me to SHARE. The personal experiences, wisdom and humor of our community go a long way toward easing the upheaval created by life-threatening illness. It is a gift to now work with volunteers who supply information and encouragement to others affected by the disease that impacted my life so strongly."

Andrea is the Coordinator of SHARE's Ovarian Cancer Helpline.

Arlene Matlick

"I first became involved with SHARE as a volunteer on the breast cancer helpline and quickly learned how valuable, necessary and appreciated a survivor's support is to a newly diagnosed woman. When the corporate Pink and Teal Seminars program was initiated in 2009, I became part of SHARE's staff. I was and am still thrilled to be part of this dynamic program that educates employees in their workplace about breast and ovarian cancers and empowers them to be proactive about their health. This work, and all the work at SHARE, is challenging, but it has great purpose and is incredibly rewarding!"

Arlene is the Pink and Teal Manager.

Christine Benjamin

"I first worked with SHARE as a consultant in cultural competency and the lesbian, gay, bisexual and transgender community. I was impressed by the many programs, services and support offered by SHARE's dedicated and passionate women. When I was asked to apply for my current position, I felt honored to be considered. Now I feel honored to be a part of such a dynamic organization. My areas of particular interest include programming, training, and support services for women with metastatic disease, BRCA-gene-related cancer and triple-negative breast cancer. As a clinical social worker who has been treated for breast cancer, I hope to build a program that meets the unique needs of women with advanced disease."

Christine is the Breast Cancer Program Director.

Diane D'Angelo

"I was diagnosed with breast cancer in January 2012.  It was then that I discovered SHARE's Breast Cancer Helpline.  My mentor called me every week and helped me get through every doctor's visit, chemotherapy and radiation.  She inspired me to get through each day and gave me hope.  SHARE was there when I needed them and I wanted to become the lady on the receiving end of the phone.  I wanted to help others, listen and give compassion to women who are facing breast cancer.

I became a breast cancer helpline volunteer in November 2013 and in March 2014 I joined the staff.  I continue to work on the helpline and have become the Breast Cancer Helpline Scheduler.  I am proud to be part of SHARE."

Diane is the Breast Cancer Helpline Scheduler.

Gladys Udewitz

"I learned about SHARE through the American Cancer Society. After participating in support groups and reading SHARE's newsletter, I wanted to become more involved. I became a volunteer nearly eight years ago and later a staff member. I am a survivor and a volunteer on the breast cancer helpline. I feel that providing support for women with cancer is extremely important."

Gladys is the Development Assistant.

Ivis Sampayo

"I am a proud 21 year two time breast cancer survivor and have been with SHARE for over 18 years! Originally I was the LatinaSHARE Director and worked with a wonderful group of volunteers and part time staff to accomplish the many goals our program had. We were able to enrich this program from 1 educational program a year to over 57 programs and we also increased our community efforts and Spanish support groups! Now as the Senior Director of SHARE I am able to work with a wonderfully dedicated staff to enrich all our programs and to increase diversity. SHARE continues to amaze me with all the love, support and hope we bring daily to other survivors and their families and friends."

Ivis is the Senior Director of Programs.

Jackie Reinhard

I knew about SHARE's fine reputation from my work at the Lymphatic Research Foundation, and I learned the value of peer support from my own experience with breast cancer. Once diagnosed, I turned to my best friend, who was also being treated for breast cancer, for advice. Now I feel privileged to lead this organization that is accomplishing so much to support people affected by breast and ovarian cancer."

Jackie is SHARE's Executive Director.

Jennie Santiago

"I became involved with SHARE as a member of the LatinaSHARE support group in Queens when I was diagnosed 10 years ago. I soon realized how fortunate I was to be bilingual and able to advocate for myself as a patient. Many of the women in the group were native to South America, spoke little or no English, and were in this country alone facing a major health crisis. I began volunteering and was so impressed by LatinaSHARE's efforts to help Hispanic women that I recommended that it be honored at the Annual Gala of the Latino Lawyers Association of Queens County, which recognized LatinaSHARE with a generous donation and an award for community service."

Jennie is a Co-Director of LatinaSHARE.

Kari Reynolds

"I have spent much of my career and volunteer time advocating and fundraising to advance women's health and rights. Having lost friends and relatives to breast cancer and having been a care-giver, I was drawn to the opportunity to join the SHARE team — incredibly dedicated staff and volunteers working to provide hope, support and empowerment to women affected by breast and ovarian cancers."

Kari is the Director of Development.

Marina Mazina 

"After working at SHARE for 18 years I was diagnosed with breast cancer myself.  SHARE became the best place I could be for my situation.  I had the best of everything - the best advice in every little step starting from the surgery and going through chemo, radiation and recovery, and I had the best support I could ever have.  I was in exactly the right place at the right time."

Marina is the Program Manager.

Deb Hackenberry

"In a doctor's office I saw SHARE's Program Guide. The breadth and depth of support and information SHARE provides for women in their hour of need really impressed me. I wasn't sure where I was going to do the greatest good but I just knew that I wanted to part of SHARE. Four years later I continue to co-facilitate a  DCIS support group and am a peer on the Breast Cancer Helpline."

Deb is the Data Manager.
