Leadership and Program Managers

Heather Gehrke, Executive Director
Heather graduated from UW-Milwaukee with a Bachelor of Business Administration, majoring in Finance and Real Estate.  She has also taken non-profit management courses through UW-Milwaukee. Most of Heather’s career has been in the non-profit sector.  It is Elmbrook Humane Society (EBHS) who moved Heather to become involved in animal welfare.  After adopting Teki from EBHS in 2000 during the first ever “Scratch and Dent Sale” of 2000, she was moved by the great work our team at the time carried out each and every day and became a volunteer.  She spent time with our dogs, volunteered at Wag Walk (now Wagfest), and served on our Board of Directors before moving to Onalaska, WI.  Heather was the Executive Director of Coulee Region Humane Society from 2004-2012.  She took a short break from animal welfare and joined the EBHS team once again in April 2013. When Heather thinks about the work we do every single day to positively impact the lives of animals and humans, she can’t imagine anything more rewarding!  Heather is very lucky to have parents who involved pets in her life since childhood!  She has currently been adopted by a 7 year old Siberian Husky who is deaf and super smart, knowing sign language and working to become a pet therapy dog. She also has an 8 year old DMH feline who found his way into her life first as a foster as the result of being a burn victim and then permanently as a result of adoption. Heather enjoys traveling – returning from time to time to a few of her favorite spots as well as exploring new places. When not traveling, working, or volunteering, she enjoys sticking close to her home spending time with her dog and cat, family and friends, and relaxing in her backyard. Choosing a quote is tough as there are many quotes Heather finds inspiring; one of her favorites is, “I’ve learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel.” ~ Maya Angelou


Anita Alfaro, Annual Giving and Special Events Manager

Anita attended UW-Whitewater with a BA in Communications and a minor in Recreation. Before working at EBHS, Anita’s family fostered cats and kittens through another organization for four years.  Anita has worked in development and event planning in the non-profit sector for over seventeen years and she loves it!  Anita’s family has three cats (Nacho, Sweetie and Callie), two cockatiels (NeNe and CoCo), and five goldfish that have all been won at area church festivals by Anita’s son. In her free time, Anita loves spending time with her family and friends, crafting, reading, shopping, being active at her son’s school, and watching Brewers games.  She and her husband also enjoy watching their son swim, playing video games with him, and watching him play percussion in his Middle School band. Two of Anita’s favorite sayings are “You Rock” and “Always Smile”!

One of Doreen’s favorite quotes from a woman she admires is, “One thing life has taught me: if you are interested, you never have to look for new interests. They come to you. When you are genuinely interested in one thing, it will always lead to something else.” ~ Eleanor Roosevelt

Shelby hopes for a program that she can help out with that includes animals and the elderly as it is very therapeutic to them. During her free time, she loves to be at home with her two cats, Callie and Tweet who were adopted from EBHS, visiting her past residents, camping, being around family, and enjoying life as it is. Shelby’s favorite quote is advice from her father, “If it scares you or it’s out of your comfort zone, do it anyways, it will almost always be the change you needed”.
