Deborah Mitchell, D.V.M., M.S.
Our Medical Director and Practice Manager


Dr. Deborah Mitchell is still as passionate about pets as she was as a 6 year-old in a crumpled and dirty Sunday dress, being scolded by her Mom. Her Mom recalls telling her that she shouldn't have been getting all dirty by playing with strange dogs and cats, and hearing: "But Mama! They're NOT strangers - they're my friends!". 


Today, Dr. Mitchell feels as privileged to care for your pets as she did when she first earned her veterinary degree from the University of Illinois in 1983. And, she still speaks the same Dog, Cat, and Bunny that she learned from her animal friends on those long-ago Sundays. Dr. Mitchell's overall medical focus is wellness maintenance. In other words, she works with you to show you the tools you need to keep your pet vibrantly healthy and happy. She understands that for pet-lovers like herself, our pets are our family and our dear friends.

In addition to serving as our hospital's Medical Director and Practice Manager, Dr. Mitchell sees patients at our hospital Monday through Friday every week. She will maintain this schedule through all of 2021, and is available by appointment only. 


Dr. Mitchell practices integrative medicine - not holistic medicine. This means that as appropriate, she combines the best that her traditional Western medical training has to offer with the best of the alternative therapies in which she is trained. This gives your pet more tools for healing - and for wellness maintenance. For consultation patients referred by other area veterinarians, the integrative therapies she offers can greatly enhance the work that your primary care veterinarian is doing to keep your pet healthy and happy! 


Dr. Mitchell  shares her life with her partner and with two four-legged friends: Cairn Terrier Bettina, and Terrier mix Walter, both "rescued" pets. Walter and Bettina come to work with her every day, and would love to meet you. In her spare time, Dr. Mitchell gardens, reads, kayaks, continues her studies in integrative veterinary medicine, and is active as a volunteer with the Greater Chicago Food Depository. As a recognized expert lecturer in veterinary acupuncture, veterinary chiropractic, traditional Chinese herbal medicine, Reiki, Bach flower therapy, homotoxicology, and integrative small animal medicine and practice management, Dr. Mitchell lectures to veterinary audiences nationwide.

Knollwood Extern
Wictora Niewiadomski 

Wictoria is a student at the College of Veterinary Medicine, at Warsaw University of Life Sciences in Warsaw, Poland. She's from Lincolnshire and earned her B.S. from The University of Madison in Wisconsin. She's previously completed externships at Piskatee Bay Stable in McHenry, where she worked primarily with horses, and at Spay Me! Veterinary Clinic in Madison, WI., where she worked with small animal surgery patients before, during, and after their surgeries.

Wictoria has a strong, life-long interest in holistic and integrative medicine, and hopes to gain more knowledge to help provide her with a good foundation in this important aspect of animal care. She also has special interests in cardiovascular patients, and is hoping to work with as many Knollwood pet parents as possible during the month of August, when she will be here during all hours of hospital operation.


Michelle Alcantar, RDH
Hospital Administrator, Head Nurse, CPR-certified (ACVECC pending)

Michelle has been utilizing her Dental Hygienist, Veterinary Nurse, and management skills in Chicago-area veterinary hospitals for nearly 30 years. She worked for our hospital in the 1980's, then moved up the management ladder, culminating in assisting with opening a major specialty center in our area. In 2020, with her 2 children grown (the youngest just finished high school), she felt ready to come back to a more relaxed and integrative style of practice. She contacted Knollwood, and we were delighted to welcome her back.

Michelle possesses top-notch communication, team-building, and leadership abilities, and is an exceptionally skilled dental and surgical Nurse. We'reloving working with her again, and know that you will, too! At home, Michelle enjoys the companionship of a Doberman, a German Shepherd, and two rescued kitties.  


Kimberly Jones
Head Receptionist, Integrative Consultation Coordinator

Kim grew up in Bloomingdale, IL. and has many years of experience in serving the public, starting out as a gift shop manager on a cruise ship. She then developed a stellar customer service career in the travel industry as an agent for over 18 years, including during the unimaginable stress of 9/11. Kim's career in veterinary medicine began in August of 2012 at a Glendale animal hospital, where she remained until relocating to our area recently. Her amazing sense of humor has us all laughing even on our busiest, most hectic workdays.


Pets have always had a special place in Kim's heart. She shares her home with two senior rescued kitties, Charlie and Oliver - and she is thrilled to be a part of the Knollwood cat-loving family!  Kim is assisted at the front desk by Nurse Hannah.

Client Connection Specialist 

Maureen's years of experience working in a large area vet hospital, before jointing our staff in 2019, remain as much of an asset to us as is her caring demeanor and calm,positive energy. Maureen headed up our Reception Team before family needs required a move back to her native Arizona. We were delighted that she chose to remain with us, working remotely as the need arises, to bring news and updates about Knollwood events and integrative healthcare to our clients via electronic media.

So...when you're freezing your tootsies off during a cold Chicago winter, you can think about sun-drenched Maureen in Arizona - and perhaps feel just a little warmer!
