09/10/13 5 2 1 1 In 1988 my six year old son developed a sebaceous cyst in the Nasolabial fold. We were referred to Dr. Guenther by our Family Practioner. All these years later I have never forgotten what a cold, uncaring doctor she was. We visited her clinic regularly for injections to reduce the size of the cyst, she then opted to remove it. I asked if there would be much scarring, and if a referral to a Plastic Surgeon was the next step. She laughed at me and said she would do the procedure. My son has been left with a significal scar all these years. She commented since he was a boy, that any minor scaring wouldn't matter. She treated me as if I was an idiot. She was not kind, gentle, nor compassionate to my son who was extremely polite and well behaved in her exam room, but naturally leaned away as he was being injected, and she even yelled at him to "hold still" during the surgery. He was barely moving, and was just a little boy. I had to ask to be allowed to hold his hand.

09/07/12 4 4 4 4 I have severe psoriasis and have participated in 2 biologic studies, the first from a dermatologist in London whom was horrible and the second with Doctor Guenther. Her staff is very friendly and helpful. Wait times have not been more than 5 minutes and Doctor Guenther has been very thorough spending adequate time with me to answer any questions or concerns. I've seen three dermatologists in London and Dr. Guenther has impressed me most to date.  Respond

24/01/12 3 2 1 2 I do not mind waiting half an hour to see a doctor. However, I do expect to be treated with respect. Dr Guenther had me strip naked & slowly rotate in a circle while she sat on a stool 4 ft in front of me to inspect moles. This was my first meeting with her and there was no introduction. Her manner was abrupt & spiteful. I was so embarrassed. I asked her about some other discolorations on my skin that my family doc told me to show to her while I was there. She refused to answer me! On my second (&last)appt her attitude was no different. My husband has since been to her and she apparently treated him very well. I think she only likes men. I overheard her talking to some factory workers exposed to chemicals and she was falling over herself with kindness. I even wondered if it was the same doctor.I have spoken to 2 other women with the same experience as me. My doc admitted that she has other patients that will not see Guenther any more.  Respond

23/11/11 3 1 3 2 1. Punctuality: I've gone four times and always waiting 60 minutes. Two of those times they apologized for the wait. So, bring a good book. 2. Patient assessment: Did not listen to my complete story, cut off my words, did not make me feel welcome, did not leave any time for my questions. Appointments are all under 5 minutes.3. Meds: I said up front no accutane for acne, so I'm using tetracycline and she's aiming for the lowest possible dose, which I respect, but she hasn't taken any time to understand when it doesn't work. This is the most disappointing part. 4. Overall: It was clear to me before reading any other posts that she overbooks and is more interested in cancer patients as a specialty. She would be well advised to get a second doc in there for more routine cases if she really cared (and stopped to think) about the best way to practice for the good of patients. I would prefer to see Dr. Gilpin if I could. Her pesonality suggests she wouldn't care about ratings.  Respond

12/01/11 2 1 2 3 this doctor is totally disrepectfully to patients. I have taken my daughter perhaps 5 times and each time have had to wait an hour for 2 minutes of her time. My daughters skin is exactly the same-she has no concern. Her nurse attempted to make me feel guilty about the amount of time I waited because of the cancer patients the doctor was seeing. Her office overbooks -this is an understatement. I will not go back.  Respond

15/04/10 4 1 1 1 I saw Dr. Guenther for a red patch on my back. The first time she misdiagnosed it as excema and upon second visit and my insistence that it was more than excema Dr. Guenther non-challantly stated, "Oh yah I think it is skin cancer. If you want to stay I will biopsy it after my physio appointment." In her rush to get to her appointment she made my son and I feel that we were on an assembly line. My mole check which I was also referred for couldn't have taken more than 20 or 30 seconds. Needless to say I did not stick around. I went back to my doctor and asked for a referral to a competent dermatologist. This new dermatologist biopsied the patch on my back and a nearby suspicious mole she found. I am now being treated for melanoma. I feel so blessed to be in good hands and getting the care I need. I am very concerned for the health of others. Please avoid this doctor.  Respond

02/02/10 5 4 5 5 The staff were very efficient, professional and polite. The nurse took an extensive history of my son's condition and we came prepared with a list of all medications that had previously been prescribed. Dr. Guenther did a thorough examination and recommended a treatment program which began that day. All questions were answered by Dr. Guenther or her staff and questions that arose after our appointment were cleared up by a quick call to the office. I noted a number of complaints surrounding wait times however our wait was pretty standard in our expereince to see a specialist with this level of expertise.  Respond

26/03/09 1 1 1 1 It took me longer to walk back to my van than I spent with this Doctor.She was 50 minutes past my scheduled time to see her.Which leads me to believe she over books.She never looked at my skin,or ordered any tests.Asked only 2 questions and then spoke over me,when I tried to answer them.She was already writing a prescription before anything was asked.She prescribed over the counter skin cream,which I had already been using.Which she would of known if she didn't interrupted me in my attempt to tell her this.She had no answers what happened to my skin.10 Months wasted waiting to see this fool. This Doctor is a complete ripoff to the Ontario Tax payer and OHIP.  Respond

19/02/09 3 3 1 4 Even thou Dr.G is known as an industry expert, i get the impression she is really only interested in extreme cases for her "clinical trials". I agree with what many have said - her bedside manner is horrible and she brushes you off if your problem is deemed "minor" to her. You can see that she herself had skin probs when she was younger so i think if you show her a red patch/blemish that are a concern for you, she sees that has so minor compared to what others/she had to deal with. But she forgots that those blemishes are a big issue to someone that hasnt had them before. She needs to be more understanding of her patients that arent great clinical opp's for her - they are just patients wanting proper diagnosis and care.  Respond

18/02/09 3 1 1 1 I waited 13 MONTHS for an appointment and spent less than 2 minutes in her office! She looked at the bumps I had beneath my eye and said "There's nothing I can do. But you do have rosacea - see the desk". The desk gave me "her" cream and a business card for her friend the Laser Doctor. My cosmetologist said I do not have rosacea, just redness on my chin. I never did find out what the bumps were. NEVER NEVER NEVER again. I'd rather treat myself. I have seen alot of Docs (fibromyalgia) and she is by FAR the rudest and worst I have ever seen....she seems like a very angry woman, time to leave her practice maybe?  Respond

18/01/09 1 1 1 4 I was referred to this Dr. by my family doctor for redness on my face, caused by acne. The cream she told me to buy, from her internal 'store' had the one and only ingredient in it that I specifically told her I was allergic to. I had to do my own research to find the product ingredients, because my condition was getting worse, and this was after I specifically inquired at her office about the ingredients, and was told the product was fine for me. Does she listen? hmmm....I won't be back.  Respond

06/01/09 3 3 1 1 I've gone to this doctor a total of 3 times and I think I've only seen her face for a total of 15 minutes. Her diagnosis always seems to be the default medication for whatever the problem is, even if I've used it before and it didn't work. Perhaps if she worked more than the barely 30 hours a week she's have time to talk to her patients.  Respond

28/10/08 5 5 5 5 Lyn is very respected in the medical community. She works very hard to deliver good care. People often get sent to her if they are not sure what to do. I think people are negative because she is so busy and can't spend a lot of time with her. The problem is not enough doctors!!!  Respond

19/10/08 3 1 2 2 I saw this doctor for 4 years for having bad acne. I was never a big fan of hers but what really made me a bit peeved was when she prescribed me accutane (most serious treatment for acne) for the third time, which I'm not even sure if people are supposed to go on and off of it three times, and told me I would have the driest skin I've ever had. I asked, drier then before? She replied, Oh you've already been on accutane?!? Therefore she has little interest in her patients and seems to have wanted me out of her office as soon as possible. She was also rude when I asked about dermatologists in the Waterloo area since it is closer to my school and she suggested I just take a bus to London! No big deal! Uhh makes me angry thinking about the time I wasted under her "care".  Respond

27/09/08 2 5 2 3 I had the impression she is inundated with patients and could care less about individuals. She missed a huge problem I repeatedly pointed out to her. Average time spent on several visits over the years is 2 minutes per. If she gets paid per patient visit she is a zillionaire.  Respond

12/04/08 3 1 1 1 I have seen her twice and each time waited over an hour in the waiting room. She barely looked at me when we did meet and she didn't say much either - spent more time writing notes and writing up a prescription - she barely looked at my skin condition. She only met with me a total of 5- 10 mins each time and seemed to be in a hurry even though the waiting room was empty. The prescriptions did not clear up my condition either.  Respond

30/01/08 3 2 1 1 Very unhappy with the experience at this clinic. I believe I was not given enough info to give an informed consent with respect to liquid nitrogen being sprayed on my face to remove sun spots. I found this Dr. to be very abrupt, and quick. I followed up with her 6 weeks after the procedure, teary and mortified by the outcome. I was told, "this sometimes happens, hopefully it will fade over time" Hopefully she said?, no reassurance, so offer to fix it, nothing. I was not aware of the risks involved and the damage that could happen or the price for that matter until the procedure was done, I was burnt and I was handed a bill for the priviledge. It has taken over a year for the scars to lighten up but they are permanent and look worse and are bigger then the sun spots that I originally went in for. My advice, I would get a second opinion, or 3 or 4 before trying any procedure like this to help with something cosmetic.  Respond

05/12/07 1 1 1 1 I've been seeing this doctor for more than 2 years and just keep on coming back for nothing, it seemed like she was always in a rush when she comes to see a patient and it doesn't last for more than 5 minutes for her to see her patient, I think ir's just a waste of time and money on my part , nothing is changed on my problem.  Respond

03/12/07 1 2 1 2 this doctor has seen me several times for about one minute each time and barely looked at my psoriasis and has been of no help for my condition.she is very interested in studies for psoriasis but nothing done to help the patient. I felt like I was an interruption and I will not be back.  Respond

03/12/07 2 2 1 1 Dr. Guenther has to be one of the worst physicians I have ever encountered. She seems to be able to diagnose skin conditions without even looking at the patient's face, and makes the patient feel like they are seriously interrupting her day. The whole visit (roughly 60 seconds) is spent with her simply writing out a prescription and rushing you out the door, without explaining anything about your condition and simply answering any questions with 'yes' or 'no' responses. If you're lucky, she may shove a pharmaceutical company-sponsored pamphlet about your condition at you, taking the place of actually having to you herself. A very unfortunate experience.  Respond

26/04/07 1 1 1 I waited a year to get into see this doctor only for her to tell me that I should come back if the symptoms get worse becaus by the time I got to see her it was not as bad as it was when I was referred. Why should it take a year to see a specialist??????????????????  Respond

01/12/06 2 1 2 I can't tell you how much was paid to this woman because in Ontario patients are not consulted re the cost of doctors' services. This is between the doctors and the province. Not a system I approve of. All Dr. Guenther ever did for me was spray my sun spots and other skin problems with liquid nitrogen. Some of my meetings with her were over within about one minute. This is not an exaggeration. Some might have taken two minutes. She took no interest in me as a person and hardly any interest in my medical condition. She said little or nothing by way of greeting or explanation of what she was doing or why, and on one occasion when examining a lesion on my back actually groaned is disgust. I have never encountered a doctor lower in my opinion than Dr. Guenther. It is hard for me to rate her knowledge because she said and did so little in the four or five times I saw her before finding a dermatologist who is truly compentent and compassionate.  Respond
