September 30, 2019 7:00 PM

Dr. Elgar was a very nice and caring doctor. When I came to my first appointment, she was so smart compared to other doctors I had regarding PCOS and made sure she came with some conclusion about what to do by the next appointment.

September 29, 2019 7:00 PM

I love Dr. Elgar - her office is in St. Charles where I live on Mondays, so it's convenient for me. My mother & sister referred her to me after I gave birth and my original OBGYN doctor moved out of state. She is the best and makes me feel comfortable at every visit!

September 27, 2019 7:00 PM

Dr. Elgar is a wonderful, compassionate, and effective doctor. She listens to concerns and helps to tailor the experience to my needs and concerns so I walk out of the office knowing I am being taken care of well.

September 26, 2019 7:00 PM

August 25, 2019 7:00 PM

I love Dr. Elgar! She has a great bedside manner. Very friendly and personal.

August 23, 2019 7:00 PM

Dr. Elgar not only always goes above and beyond to help me with my medical needs, but goes out of her way to let me know that I am important to her as a person not just a patient!

August 18, 2019 7:00 PM

I was nervous going into this appointment. Dr. Elger was very nice and talked to me like I was a person. she took the time to answer questions and explain everything that was being done and why they needed to be done. I would definitely recommend Dr. Elger!!

July 21, 2019 7:00 PM


June 29, 2019 7:00 PM

Dr. Elgar has helped my daughter with her gynecological concerns in the past. I was so pleased with her service with my daughter so I wanted to meet with her for me as well since I didn't have a Gynecologist.

June 21, 2019 7:00 PM

I had a great visit with Dr. Elgar. it was my second time seeing her and I'll always go back, she actually cared to listen and try to help me and understand what I was going through at the time. I'd recommend her to everyone.

June 20, 2019 7:00 PM

dr. elgar is a kind,caring physician. she is very knowledgeable. always makes me feel at ease.

Dr. Elgar has been seeing me for the last 9 months for my first pregnancy. she has taken care of all my needs and has been a great listener.

June 14, 2019 7:00 PM

always pleasant visits

May 20, 2019 7:00 PM

Really seems to care about my health.

May 13, 2019 7:00 PM

She is amazing, makes me feel so comfortable every visit. She is compassionate and checks on other things in life not just what I'm there for. One thing that I know to be true at every visit with her after we are done she will lift you up and get you feeling great and smiling before leaving. This is great because you leave happier than you thought, especially if you get some not so good news.

April 19, 2019 7:00 PM

Wonderful! My husband and I both loved Dr. Elgar.

April 16, 2019 7:00 PM

She was great. Great bedside manner.

April 14, 2019 7:00 PM

Corissa Elgar is very attentive to my questions and needs. She is very informative with information she provides whenever I have a question regarding issues I may be experiencing.

March 28, 2019 7:00 PM

Easy to talk to & understand. Love her!

March 27, 2019 7:00 PM

This was my first visit with Dr. Elgar for a routine OB visit. I enjoyed her straight forward and jovial attitude, and loved that she had a full face of makeup! It made her relatable.

March 2, 2019 6:00 PM

Dr. Elgar is professional and easy to talk to. She is concern and takes time to listen.

February 27, 2019 6:00 PM

Dr. Elgar was amazing as always. A womens' wellness exam is not the most comfortable experience, but Dr. Elgar has a way of making me, and I'm sure the rest of her patients, feel so at ease the whole time. I recommend her to all my friends.

February 24, 2019 6:00 PM

I usually go to the St. Charles location and wait for a very long period of time and typically do not have a great experience. I went to Aurora due to scheduling conflicts, and I will be going to this location going forward. The staff was wonderful and friendly and I was shocked at how quickly I was in-and-out, while still completing a thorough visit.

February 17, 2019 6:00 PM

Dr. Elgar has been fantastic! We've recommended her to several family & friends already.

February 17, 2019 6:00 PM

Very good.

February 6, 2019 6:00 PM

love dr Elgar! always open, honest, straightforward, and she listens and asks questions

January 25, 2019 6:00 PM

love my doctor she is wonderful I would never go to another Gynecologist. She is great at what she does. Very caring and helps explain everything you have questions about. The rest of the staff is very helpful and knowledgeable as well.

January 14, 2019 6:00 PM

I thoroughly trust and have a great relationship with Dr. Elgar. However, I am recently less satisfied with the scheduling process at the reception desk. At my most recent appointment yesterday on 1-14-19, I arrived at my assumed scheduled time, to be told there was no appointment in the system that day for me. The office staff accommodated my need and I was able to see another doctor. Before leaving I requested a list of upcoming appointments to which I found another error in appointment times for the next weeks that I had to reconcile. I'm concerned that my appointments will be confused at another time, and I want to be able to rely on this office.

January 13, 2019 6:00 PM

I love Dr. Elgar! She is wonderful.

January 13, 2019 6:00 PM

I absolutely love Dr. Elgar! She is an amazing person as well as doctor.

January 13, 2019 6:00 PM

Dr. Elgar is professional, knowledgeable and approachable. I feel that I am on very good hands with Dr. Elgar. She has an ease about her alongside a wide knowledge base. I ha e recommended her to friends.

January 13, 2019 6:00 PM

Dr. Elgar is the OB I had always hoped I'd have. She's VERY personable, explains everything well, and talks me down off ledges when my anxiety grows! I can't say enough great things about being under her care. I feel very fortunate to have found her.

January 13, 2019 6:00 PM

I drive an hour each way to see Dr. Elgar. She always respects my time, never makes me feellike my questions or concerns are not valid, and somehow manages to make an overall uncomfortable appointment very relaxing and comfortable. I can't imagine seeing anyone but her!

December 1, 2018 6:00 PM

Everytime I go to Dr. Elgar I feel my concerns are validated as she answers each of my questions. I always have concerns about my reproductive health and EACH sand EVERY time she listens and answers those questions compassionately. You can tell she loves her job since I have always met her with a very positive deameanor throughout my visit. I had gone through a few gynecologist through your practice and once I met her I have and will NOT switch doctors.

December 1, 2018 6:00 PM

I couldn't ask for a better doctor.

November 26, 2018 6:00 PM

The front desk receptionists were very nice and helpful. I was seen in 2 minutes; no waiting!! Nurse that took my vitals was very professional and nice. Dr. Elgar was a sweetheart. Dr. Elgar was helpful, offered some great advice, very friendly, nice. All were very impressive.

November 26, 2018 6:00 PM

With the doctor was very good.

November 26, 2018 6:00 PM

Dr. Elgar is amazing. This was my first visit with her and she explained everything to make me feel comfortable. Thank you so very much!

November 19, 2018 6:00 PM

I found Elgar to be the best doctor amongst all I have met, I would love if she delivers my baby.

November 18, 2018 6:00 PM

My visit was excellent!
