Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Dr. Tilles does not know anything about skin cancer. After a few years of being told that a large apparent mole on my flank was nothing to worry about, that "nothing" has since been diagnosed as a melanoma and a deep one. Surgery and possible thyroid cancer treatment are in my very near future. I should have listened to my instinct!

Dr. Tilles has been my primary care physician for almost 15 years. I have a high confidence in his ability. He clearly explains why he does and doesn't recommend things.

Dr. Tilles has been my personal physician for many years and is, in my judgment, a top notch doctor who has always treated me with great care, experience, knowledge and thoughtfulness. He is always caring, friendly and respectful and has always prescribed the best treatment for my specific conditions as required. My current visit for my annual physical was no exception and in spite of the current pandemic, I felt perfectly comfortable and safe his offices in which the most careful procedures were in place and observed by him and his staff.

I would definitely recommend Dr. Tilles to my family and friends. I started seeing Dr. Tilles over 20 years ago when he was at Concord Hillside. I just transferred over to Emerson Primary Care when I heard he was taking on new patients. Dr. Tilles has always been someone I have been able to relate to. He has always displayed an interest in my overall activity and advice when he believed it was relevant.

Dr Tilles is an excellent PCP. His appointments are timely and most times does not keep you waiting. He is thorough with his process, and he cares about his patients. He balances his recommendations/care with reasonableness and thoughtfulness. I've been going to Dr Tilles for many years and followed him to Emerson from his prior office.

Very easy to schedule an appointment with Dr. Tilles. He is very thorough and knowledgeable. He was able to provide very practical advice that I was able to apply on my own without additional treatments. His personality and bedside manner are great and I felt very comfortable with him immediately.
