I seek to listen and understand. To cure if we can; and treat for comfort if we can't. To care, always.

Since joining the Froedtert & the Medical College of Wisconsin in 2002, Dr. Santo Tomas has led teams tasked to improve patient care and outcomes for hospital and clinic patients. Though he sees a wide variety of respiratory diseases, colleagues in pulmonary medicine have particularly sought his assistance and second opinion on patients with work-related lung disease, interstitial lung disease and pulmonary complications in hematopoietic stem cell transplant patients. He has been voted by his peers to the Best Doctors list every year since 2005.

Dr. Santo Tomas was extremely professional in demeanor and appearance, yet personable and friendly. He is knowledgeable and instills complete confidence in his judgement. Very happy to have him for my doctor!
I trust Dr. Santo-Tomas. I know I am in excellent hands when I see him.
I seen Dr. Santos last year for a second opion by my Dr. He said if for any reason I could come back. Well It's a yr. And nothing changed were I go. So I'm back and I really like him as a Dr. And I will keep him as a Dr. I drive 50miles to see him but it's worth it."Thanks to all"
Excellent explanation given for test results. Very professional staff and there was no wait once I was checked in.
Dr. Santos Tomas is a very nice man. He really paid attention to me. He's a good listener.
The dr.spent time with me at the appointment and didn't make me feel like I was keeping him from his next appointment. He looked at me when he was talking to me, not at the computer like some drs do. He answered my questions thoroughly.
Doctor was thorough. Very informative.
The nurses and Dr Santo Thomas are the best care givers I have encountered in my life journey. They are caring and helpful and I feel they are aways willing to help. That is greatly apperciated.
Appreciated Dr took the time to answer my family's questions.Especially, granddaughter in Medical School.
This was my first visit to your clinic. All the staff were very friendly and helpful. The doctor I saw was extremely thorough and listened to what I had to say about the reason I was there. I already have recommended this clinic and doctor to others.
Everyone was very professional and helpful.
Love Dr. Santo Tomas.very kind,easy to talk with,expert in his field.
Dr Tomas is a very Dr, he listens to your concerns and explains what needs to be done and orders tests that he feels would give answers to problems.
Dr. Santo-Tomas was superior with care & explanations. Entire experience was fine
Listened well to my concerns. Had my information right at hand.
It was nice that the doctor did not prescribe a very expensive drug that I did not need. He was very nice about explaining why the drug could be prescribed, but didn't feel I was ready for it
Dr provided very good advice- very insightful
Dr. Santo Tomas is very thorough and makes sure I understand before we disconnect.
