Overall disappointed. Never punctual with scheduled appointments. Examinations feel rushed. And a lot of questions go unanswered. This is probably why; the waiting room isn't busy, his schedule is always wide open, he accepts any and all insurance under the sun, and he is always looking to find new patients.

All That I Want in a Doctor

After experiencing a string of PCPs who didn't work out for various reasons I happened upon Dr. Erler. With many doctors you feel like they're rushed, your problems aren't very important to them, and the relationship between you and them is like the relationship between a pompous professor and a freshman. Not so with Dr. Erler. Dr. Erler provided all the time I needed to describe my concerns. He didn't interrupt, but did take the time to ask about my problems in detail. It appeared to me that his examination was thorough and his recommendations correct. Most surprisingly, when I asked him a question he didn't know the answer to he actually said he didn't know but would investigate and get back to me. The tenor of the interaction was just what I was looking for: that of two intelligent, concerned, and reasonable people working together to solve my problem. I couldn't ask for anything more.

One of the worst doctors I have seen

This doctor is horrible, he refused to treat my back pain because he considered it "chronic" and doesn't treat chronic pain. I had back surgery six months ago and have been recently been having increased pain, I explained this to Dr. Erler and also that I have an appointment scheduled with a specialist, but it takes about a month to be seen at any of the places I called. He proceeded to tell me that he could refer me to a specialist, but could not treat me. If I needed immediate treatment for my pain I could go to the emergency room. Also, during his initial questions he asked me several times if I could be pregnant and to explain to him speciifcally how I knew I wasn't. He then asked me to change so he could examine me, why did he need to examine me if he couldn't treat me? I left the office literally in tears with two hours of my time wasted. This guy is horrible and shouldn't be licensed to practice medicine.

Very thorough and professional doctor

Doctor Erler is very thorough and professional. Of all of the doctors I have visited over the years, he is easily the best. My wife and I followed Dr. Erler from the Brookline office to the Lexington office (much further drive) because he is the best.
