Urology
Med School/Year Graduated: University of Chicago, 1992

Which are the most common issues you treat? Are any urological issues trending downward thanks to advanced technology or awareness?
Prostate cancer is the most common condition that I treat, although I treat the entire spectrum of urologic malignancies. The advancements in prostate cancer management, particularly in the area of medical therapies for advanced cancer, are thankfully extending the lives and minimizing the harm caused by this terrible disease to patients… and new advancements are continuing to occur at warp speed!

People tend to think of urology as a field geared toward male patients. Is this true? What proportion of your patients are women?
Urology is a field encompassing care for conditions specific to both males and females. While I see a majority of male patients due to having a practice focused on prostate cancer, approximately 35 to 40 percent of my patients are women who are seen for other urologic malignancies including bladder, kidney and upper urinary tract malignancies – as well as kidney stone disease.

Do you keep in touch with any former patients? Is there a case that was especially gratifying?
Yes… I was gratified to have cared for a patient who had given birth to her first child and two weeks later was diagnosed with a large kidney mass that proved to be malignant. She underwent surgery and has remained cancer-free. She has since had another child as well, and to see her family grow over time and hear the stories about all the love and life she continues to share with her family is an incredible gift in my life.

What is benign prostatic hyperplasia? What causes it and how is it treated?
Benign prostatic hyperplasia is an enlargement of the prostate that occurs in men as they grow older. Men often notice its presence if they start to have to get up at night to empty their bladder, as the enlarged prostate prevents the bladder from emptying completely. There are a variety of medical and surgical therapies available to treat men with this condition, depending on the size and anatomic configuration of the prostate. Prostatic arterial embolization is one of the new additions to the treatment options showing great results for patients.

You’re a big traveler! Which destinations are next on your bucket list?
I would love to take a trip to Antarctica! No immediate plans, but when I can find the time, I would love to go.

“If I wasn’t a doctor, I’d be…”
A foreign service officer. I’ve always been fascinated with the workings of international diplomacy and often wonder what a life lived in that world would be like.

Vascular Surgery
Med School/Year Graduated: Rutgers University, 2009
Years in Practice: 9

On which part of the body do vascular surgeons do most of their work? Where does vascular surgery end, and cardiovascular surgery begin?
I actually get this question often from acquaintances as well as patients and agree that it can be confusing. While practice patterns do differ across the country and between institutions, generally speaking, vascular surgeons operate on all blood vessels, including arteries and veins, outside of the heart and brain.

Your field requires you to plan and perform multidisciplinary procedures. What do you enjoy most about working with other physicians to improve patient outcomes?
Vascular surgeons are in a unique position to help other services when operating on or near major blood vessels. These multidisciplinary cases are some of my favorites, because each one is unique. Mayo Clinic does a great job at facilitating this type of multidisciplinary care, and it’s always a great feeling when you can walk away from a complex case with a team win.

Surgery is so complex and technical. Did you always have an “engineer’s mind” that wanted to understand how things work? Did you take things apart and rebuild them as a child?
I’ve always liked technical challenges, but there’s an element of art in medicine, and surgery enables simultaneous technical and artistic expression. The spectrum of treatment modalities in vascular surgery is extensive – from the latest in minimally invasive technology to operations which have not changed significantly and been the gold standard for many decades. I love being challenged by different types of surgeries and tailoring the treatment to each patient.

Do you have any interaction with patients post-surgery? Have you kept in touch with any over the years?
One of the things that I love about vascular surgery is the longitudinal care we provide patients. We follow patients long-term to monitor symptoms or to ensure that surgeries that have been performed continue to serve the patient as intended. When we are not planning an operation, our primary interaction with patients is frequently explaining a new diagnosis – for instance, carotid stenosis or peripheral arterial disease – which does not require immediate intervention, and these interactions are focused on surveillance and long-term follow-up.

What are your interests and hobbies outside medicine?
I love spending time with my wife and daughter when I’m not working. We just adopted a rescue dog named Squirt to join our small but growing rescue family, which already includes a cat, Badger, and a dog named Boots.

What are you streaming on TV these days?
My daughter and I are working through the MCU [Marvel Cinematic Universe] movies in order. It’s fun to see her experience the years-old franchise for the first time.
