J Keith Lemmon

Dr. Lemmon is an excellent allergist. He was able to diagnose and successfully treat my very complicated medical condition. Because of him, I no longer suffer from debilitating asthma and allergies. He is a compassionate doctor with an awesome bedside manner. I’ve recommended him many times over the past 5 years and all of my friends and family are pleased with his service, as well.

Dr. Lemmon is simply an outstanding physician. He's friendly, responsive, and eager to resolve a health concern or issue. Both my kids and I see him and he's great with all ages and conversations. Very thorough and patient. I highly recommend him.

Brilliant, friendly, empathetic. This one man show is better run than any big health system. He is the 3rd allergist I've ever worked with and never in my life would I leave Dr. Lemmon, he's just great to work with. He will get to the bottom of your issue no matter what it takes. Getting an appointment, billing your insurance, answering follow-up questions after the appointment - it's unbelievable how well he runs his practice. I can't say enough good things about my experiences with him.

I highly recommend visiting Dr. Lemmon. He is brilliant. I have been seeing him for allergy shots for a few months now and already feel a difference in the day to day. He is very charismatic and passionate about his practice. He genuinely cares for each of his patients and makes you feel super comfortable. I would also like to point out how organized and methodical he is which is incredibly important in his field. He is flexible and will do his best to make sure you get in when you need to. I have a pretty last minute schedule myself and he is always accommodating to last minute appointment changes. Not only is he a trustworthy healthcare provider but he is a complete joy to visit. From the music he plays in his waiting room to the thought provoking and goofy conversations, I always learn something new and enjoy visiting him. Great guy, great doctor!

Dr. Lemmon is a caring and compassionate solo practitioner who always goes the extra step to meet the health care needs of his patients. You would thin that since he operates without staff that it would be hard to get a hold of him--but the exact opposite is true. If you need him for an urgent health issue he is available. I couldn't be more pleased to have access to him as my allergist/immunologist.

I moved here to Glenview and needed a new allergist. Looked up AllergiSt’s in my area and he seemed to have the best reviews. Reviews weren’t wrong, Dr. Lemmon is an amazing allergist. He listens to you, answers your questions patiently and explains things thoroughly. I never felt rushed and he knows what he’s doing. I recommend him if you are in search for an allergist.

Dr. Lemmon is amazing! He has a great set of soft skills along with a high level of knowledge and expertise in the allergy and immunology field. He is very accommodating and helpful. I would highly recommend him!!

I have been seeing Dr. Lemmon for two years. It started with a referral from my internist - a test to see if I was allergic to a particular medicine. We started talking about allergy shots so I could get some relief from allergies. Fast forward two years: things are going great - I am feeling better than ever. Keith is a great doctor - an amazing combination of smarts and warmth. He is expert and also caring and I'd recommend him for children and adults.

I have been seeing Dr. Lemmon for 10 years. He is my favorite Doctor as he always demonstrates concern, knowledge & care for all of his patients. He even made sure I was well taken care of when I lived in Spain. Dr. Lemmon will take the time to listen to you and thoroughly provide advice and care to all of his patients. He is also amazing with young children. Asthma can be a scary issue to deal with but Dr. Lemmon keeps it under control. You would be crazy to see anyone else. HE IS THE BEST!

One of the most proactive things I've done to improve my health was to see Dr. J. Keith Lemmon 7 years ago. He diagnosed me with severe allergies, started meds and shots and I feel like a new person. Dr. Lemmon is an outstanding medical professional who really listens to his patients, and really cares about their health. He returns all calls himself. makes himself easily accessible, is current with all the latest allergy and asthma innovations. and never makes you feel rushed. THE PERFECT DR.!
