Why home vet care? Do you dread having to fight with your cat to get him or her into the carrier? Does your pet hate car rides, or even get sick in the car? Does your older dog have a hard time walking on slick clinic floors? Do you have multiple pets that you would like to have cared for at once? These are just a few of the many reasons people choose to have the veterinarian come to their home.

Having a vet visit in the comfort and familiarity of home makes the entire process minimally stressful. It also helps the veterinarian see your pet in his or her home setting, as they really are. Yes, they often still get poked with needles, and there may be other “insulting” procedures, but having these done in a familiar environment makes the whole process a little better. And, without leaving the house, your cat or dog won’t come home “smelling different” and causing potential inter-pet anxiety.

I chose being a veterinarian as a sort of “second career” and have never looked back! I was earning a PhD in molecular cell biology at Washington University School of Medicine, when I adopted two rescued dogs. After becoming more involved with dog rescue, I realized veterinary medicine would be the best career for me. I went to University of Illinois College of Veterinary Medicine and graduated in 2004. My favorite topics are dermatology and internal medicine, which also happens to be the majority of what I deal with on a day-to-day basis.

I base my practice on a simple concept: treat people the way I would want to be treated. I take the time to explain diagnostic and treatment options, no matter how complex. I have found that when you break it down, nothing is so hard or complicated that a loving owner couldn’t understand. My clients appreciate my directness and honesty the most, even when it’s “brutal honesty” sometimes. And, I have learned that laughing a little goes a long way in this job!

My clients know I am a doctor, but I am a real person. Some of my dogs eat poop, no matter what I try. I often have pet hair on my clothes. I am a pet owner, and I know what it is like to love your pet like any “human” member of your family. I must admit that older animals hold a special place in my heart (the skinny old cats and the old arthritic dogs).

I look forward to getting to know new people and their pets! Nothing makes me happier than helping a cat or dog who has been itching, sick, or hurting, and making life better for the whole family!
