Meet the Doctors and Your Heart & Vascular Team

The doctors and your team at the Waukesha Heart Institute and the Heart and Vascular Institute are dedicated to providing you with the highest level of care and compassion when it comes to your health. From screenings to treatment to follow-up, we’ve got you covered every step of the way.

On top of being knowledgeable, you’ll find that we are friendly, respectful, and professional. You are our priority!

In addition to our highly trained and experienced healthcare professionals who utilize the latest technology, we have a dedicated team to take care of your appointments, scheduling, registration, medical records, and billing.

Our billing department is onsite, so if you have questions on what your insurance covers, and what portion you owe, we’ll be happy to go over it with you; either in-person or on the phone. If you need to make payment arrangements, we can help you there too. We can set up a payment plan that won’t break the bank and keeps you from falling behind and into collections.

You’re in great hands at the Waukesha Heart Institute.

Meet the doctors and your heart and vascular team!
