John J Guagenti, MD

I’ve been to this Dr. Multiple times for a couple different issues. Both times he knew exactly what the problem was right away. Both times he gave me samples that he had in the office instead of giving me a script that I would have had to pay for. And both times the samples he gave me fixed the problem within a couple days or so. Thanks Dr. G

On my first appt. with Dr. Guagenti he did not tell me that using the Laser would need to be pre-​approved by ins. until I asked. He then said «I don’t know». I had to ask him to please check b4 he treated me. He did and said that I would need pre-​approval first. So I left with no appt. I was called a week later and was told that I had only ONE approval from my insurance, we set an appt. for that treatment. I asked for them to contact my ins. again for the additional treatments, they said yes they would, but I never heard from them again. When I went in for my first treatment two weeks later, I was told Dr. Guagenti was to busy to request the additional treatments. Then they said «besides he needed to see you again to request more treatments, I asked „why“ since nothing had changed since my last visit there»?, they had no answer for me. I was so stunned that I gave them a «Deer in the headlights look, and went to sit down». FYI using the Laser means there should be treatments set for once or twice a week continuously until treatments ends. With no addition treatments approved I would not be able to come back for at least two weeks, which would disrupt the normal treatment flow. When Dr. Guagenti came in the room to see me I told him that I was disappointed that approval had not been made for the future appointments, at that point he said «the approval is done for you as a courtesy since the girls in the office do not get paid for that. I then said «well I can not call the ins.» and he stopped me and said «OH YES YOU CAN, LIKE YOU DID WHEN YOU YELLED AT MY STAFF, THAT WILL GET THEM MOVING». I never called and yelled at his staff, and that day there were other people in the small waiting room and I did not want to make a seen. Right then and there I decided I would not come back to his office. I have reported his actions to the insurance company and found out that the Dr. Guagenti and his staff lied to me. My insurance had approved 10 visits from the time of the first request from the staff. I have made an appointment to see a new doctor. I would not trust this doctor!!!

The main reason for writing this review is because, of all the reasons I would never go back to this office (see below), this one thing pisses me off so completely, if it convinces at least one person to have second thoughts about doing business with Dr. Guagenti’s office, I will be satisfied. Here is it: I called the office to make an appointment for a free consultation as advertised on their website in large bright blue font. Then I received a $ 90+ bill for the free consultation. WHEN SOMETHING IS ADVERTISED AS FREE, YOU CAN’T BILL PEOPLE FOR IT!
Additional complaints:
1. Office looked very cheap and outdated.
2. The doctor barely spent anytime with me (who cares if it’s free, right? but if I’m getting billed for it, it better be a experience I will value).
3. The doctor didn’t even address what I came in for (laser repair for subaceous hyperplasia)
4. I was told by the doctor, dissmissively, my «problem» wouldn’t go away.
5. Disconnect between knowledge of staff making phone reservations and what doctor is capable of.
6. After including a screenshot of the «Call today for a free no obligationcosmetic consultation 818−242−6357» and asked to have the charge removed from my account, I got another bill.
7. Billing department doesn’t understand what the word «free» means (free — adverb — meaning without cost or payment).

I called earlier this week to make an appointment with Dr. Guagenti. The receptionist scheduled me for an appointment just two days after! I arrived early to fill out new patient forms and I was taken in shortly.
I explained to the nurse my concern and Dr. Guagenti came to see me shortly. I was so glad that things went well. The procedure took no more than 5 minutes and I was on my way!
Overall, there was a great staff, very organized with their time, and got the job done! I definitely suggest Dr. Guagenti to all!

As a first time patient of Dr. Guagenti’s, I have to say he was one of the nicest, sweetest, gentlest doctors I’ve had the privilege to work with.
Polite and communicative, Dr. Guagenti removed a wart/​mole of my nose with me barely feeling a thing. Precise and well versed in his field of medicine, he handled the procedure with ease and finesse which put me at ease through out the process.
His assistant nurse as well was a doll as the needle she gracefully injected, given her supportive and calm demeanor helped make the pain of the poke not that painful.
I left the office feeling better than when I’d arrived.

Dr. Guagenti is a very friendly, personable doctor who seems on top of things. Unless you get there early and can park on the street, you have to pay for parking in the garage.
I’ve been to many other derms and Guagenti is the only one I’ve visited that is willing to freeze or remove several moles or what have you in one visit. It’s expensive, of course, but you get your money’s worth.
The office is professional. The front office staff isn’t nearly as friendly and warm as the doctor is, but they’re all pretty and I guess that’s what counts most. Hmmmm. The back office staff are much more personable.
The only thing that keeps them from getting a 4^th star is that there always seems to be some weird billing issues that take time to resolve. Aside from that, Dr. Guagenti is A-​OK in my book.

Billed me multiple times for the same thing. Phone number doesn’t work. RUN from this guy.

I have been a patient at this office for about 5 years and always have a pleasant experience. I have seen both Dr. Guagenti and the PA, Robin. Both are fantastic. I recommend them to all my friends.

Unfortunately, I cannot review Dr. Guagenti because I was seen by the P.A. She was very professional and thorough and gave me educated reasons for all of the treatment options offered. I was ten minutes early and had to wait about 30 minutes, no biggie but it felt a bit long. I would have liked to have seen the MD because this was my first visit, but overall it was a pretty positive experience.

I highly recommend Dr. Guagenti. The office is very clean and inviting, and easily located in Glendale for a Silverlake resident. He is very friendly to the gay community, which I appreciate a lot.
I was initially embarrassed to come in, but he put me at ease and quickly solved my problem (that I will not mention) in one visit. I have been back several times since.
Also, I recommend him a lot to friends and family.

I had an appointment with a physician’s assistant. It was last minute, which I was grateful for. However, I ended up not even getting the medicine I needed. The physician’s assistant didn’t call the pharmacy for prior authorization, which she should have known she needed to do because of certain questions she asked me regarding my insurance. It was a Friday afternoon, so by the time the pharmacy tried to fill it I could not contact the doctor’s office, and couldn’t get my medicine since it was the weekend and the office was closed.
On top of that, I received a shot which they did not mention would cost anything, then I got a bill in the mail for $ 90. (+ my $ 55 copay).
That’s a lot of money for dealing with a lot of BS and getting practically nothing in return.

I had struggle with acne for yeeeeeeears! I went to many dermatologist different primary doctors and nothing they ever gave me worked. I was hesitant to go see him because my insurance wouldn’t cover him. after becoming engaged I decided to give him a try since I wanted to have beautiful skin on my wedding day. I was EXTREMELY glad I went to see him within a month my skin began to clear with topicals and meds he prescribed now 6 months later my skin is amazing! i haven’t had a single pimple in over 4 months! His entire staff is very friendly and his PA-​C Robin is the best!

the Dr. was OK, he pretty much left the work to the nurses. I give the nurses here 5 stars, they are hilarious & good at what they do. the prices here are affordable too for someone like me who has no insurance.

Worst doctor I’ve ever been to! His procedures never worked! Collected so much from my PPO insurance for nothing! I asked him about 3 concerns that I have about my skin which I wrote on a piece of paper but he just dismissed me! Said we can discuss about other things on my next visit! Was in a hurry and didn’t seem to be knowledgeble @ all! I am a nurse but didn’t mention that to him just so I can figure out if he knows his stuff but he doesn’t… Did biopsy on my mole but never returned my call to give me the result! Don’t EVER, EVER, EVER go to this doctor! And I mean EVER!

One of the worse doctors I’ve seen in 20 years! One of his procedures didn’t work and yet he planned to sue if I didn’t pay for it, he wouldn’t give me lab results despite repeated requests, when I told him something was on my toe nails after showering and I asked what it was he said, «Don’t touch your toe nails after you shower!» I pushed further and that’s all he would say. Strongly recommend not going to this guy.
