Professional background: I have, of course, always loved animals and was fortunate enough to be able to combine this love with my other passion for science by becoming a Veterinarian. I have worked in many different practices over the years and I believe this has given me a unique perspective. Every Veterinarian has their own way of doing things….indeed a treatment considered wrong in one practice might be used successfully in another! This has enabled me to become more open minded and flexible in my approach. I am committed to providing the highest quality most up to date medical and surgical treatments, but over thirty years of practice have taught me that simple treatments and tincture of time can cure many ills without the need for expensive testing.

Family: I have been married to David Williams, (professor of Veterinary Medicine at the University of Illinois) for 33 years. David is currently researching weight loss in geriatric cats. We have one son, Harold who received his PhD in Mathematics from the University of California at Berkeley and is now dividing his time between two jobs, one with a start-up company developing software for driver less cars and the other as a post doc in Mathematics at UC Berkeley. He was married this past fall to a lovely women with whom he has been in a relationship with for several years. We are thrilled to welcome her to our family. We have 3 cats several of whom vomit on a regular basis and one elderly dog recently adopted from Hospice Hearts, a rescue group that finds homes for pets whose owners have either passed away or gone into nursing homes.

Other interests: I have always been interested in art and enjoy drawing with pastels. Several of my pet portraits are on display in our hospital. I also enjoy horseback riding and of course being with my family.

Robin Hadley, DVM

I have been practicing in central Illinois since graduation in 2000 and I joined Mahomet Animal Hospital in October 2020. My goal is to provide compassionate, realistic treatment to cats and dogs of all life stages. In addition to private practice, I have worked in low-cost, high volume mobile clinics, and have collaborated within my community to provide access to affordable veterinary care. I represent Illinois in the Humane Society Veterinary Medical Association, a professional organization devoted to the advancement of animal welfare. I am presently seeking certification in low-stress handling and veterinary acupuncture. My husband, Carl, and I moved to Mahomet in 2014, with our cats, dogs and horses. We both love to explore the beautiful parks in our community on foot, bicycle or kayak.

Miranda – Customer Service Representative

I am new to the animal field professionally but, growing up my family fostered many pets until they found their fur-ever homes. I am a mother of 2 wonderful children and 1 very odd cat. I enjoy cooking and hosting dinner parties for friends and family. I also enjoy watching true crime documentaries.

Kayla – Customer Service Representative

I grew up on a horse farm outside of Gibson City and have been showing horses since I was 6 years old. Growing up around various animals since I was young has helped me develop my love for caring for animals. A few years ago I had the opportunity to work in the Large Animal Clinic at the U of I in Theriogenology until I found out I was expecting a little girl. My daughter is now a sassy 5 year old and we have a 6 year old boxer named Lilly. In my spare time I enjoy spending time at home with my family and bowling league with my Fiancé on Saturday nights.
