Leonard Lem, DDS, MD

Think twice before you contact this unethical egoistic dentist. This matter is escalated to Dental Board of California because of Leonard Lem’s dishonest, manipulate and unethical conduct.
Lem overbooked patients (mostly non-​English speaking) before his vacation. The office ripped off patient since I have CBCT done in another OR’s office, they insisted that I repeat the CBCT in their office. .Lem was not paying attention to what I informed him and put down the wrong post-​implant frequency of pain and wrong tooth number. He refused to revise the appalling discrepancies in his report to my neurologist and my general dentist who caused me permanent brain nerve damage from an implant because of his connection to this GP who paid for the consultation. Not only he lied to cover the discrepancies in his report in terms of my post-​implant frequency of pain, he also came up with a phantom witness (his front desk staff) who was not in the room during the discussion of my pain. He lied, twisted facts and put words in my mouth. When I refused to be manipulated, he hung up on me.
Initially, I thought he might have mixed up the pre-​implant frequency of pain with post-​implant one. However, his lies and perjury on the phone made me believe it was done intentionally to down play to the general dentist’s advantage. Below please find my email to him after his call.
In your surprise call, you twisted the truth and put words in my mouth which is unacceptable. During the consultation, I informed you explicitly about my post-​implant multiple ER visits, the constant pain I am suffering from every day, to the extent that my helpers need to hold me while walking and the lack of sleep due to pain. I mentioned to you I only had three hours’ sleep the night before because of pain. How does that translate to pain occurrence of only three to five times a week in your report!
When I called your office regarding the errors in your report, Susan mentioned she was not in the room when we discussed the related issues. In fact, she ushered me in and left the room with my helper. When I was talking about my ability in handing stress, she came in and interrupted me to ask you about other patients. Other than that, she not present during our consultation. To state Susan was in the room and heard my post-​implant frequency of pain is despicable, manipulative and unethical.
You are not being impartial since my general dentist paid for the consultation. This is the reason you refuse to make any kind of revision. You asked me if I want you to be an expert witness which is ridiculous given your association with my general dentist and the lack of credibility reflected by the deviations in your report I was reluctant to have a consul with you because of this connection and poor Unilocal reviews. You are not the first oral surgeon who diagnosed me with neuropathic pain which I concurred. I only came to you based on my neurologist’s recommendation on biopsy to rule out the possibility of infection.
With the same training as or if not better than Warren Buffett, I am meticulous and responsible. I myself made several revisions in my reports even though they were not technical errors such as yours before they circulated in Federal Reserved system. I am still wearing different hats in my life now. Losing a sharp mind and having to reply on medication around the clock for the rest of my life is devastating. You mentioned that in your practice, no one has asked you to revise your report. Do you believe you are God? Even media makes corrections. I caught a crucial error in my orthopedics notes and he revised it without any issues. Like the other review mentioned, most of your patients are non-​English speaking ones. How many of them know how to fully understand your report? How many of them have my caliber to be able to detect the major deviations? You admitted that you have never come across any patient with my kind of symptom. So how can you deny and lie when patient tells you mixed up the pain frequency pre and post implant?
Post-​implant frequency of pain and tooth number in your report is major deviation from what I presented to you. You put down the pre-​implant frequency of residual pain (post extraction and bone graft) as post-​implant pain occurrence either intentionally or by mistake.
As a dental provider, it is your fundamental responsibilities to get the facts right and ensure they are truly reflected in your notes or report. Your report causes confusion and damages if this case goes to court since you made up evidence to the defendant’s advantage. The reason you chose to call vs. reply via email demonstrated it is a matter of ego vs. ethics. Is it professional conduct to refuse any kind of amendment and ask the patient to staple her email to your report?
The extremely unprofessional and unpleasant experience started from the time I call in spoke to «Curly» to make an appt. I am afraid all the Unilocal reviews are correct

I don’t even want to choose 1 star. Can I give negative stars? Because this place is a negative 5. I was referred by my dentist (who I complained to and is going to stop referring patients to Dr. Lem immediately)
Dr. Lem is an excellent oral surgeon. He’s very knowledgable and his work is clean. The issue at hand is his staff. Never have I ever been subjected to deal with such incompetence in a medical staff. They told me this doctor is in my network and covered up to 80% for my wisdom tooth extraction. My share would be $ 101 which I paid in full on the day of surgery. Turns out, he is NOT in my network, they made a billing MISTAKE and decided to pursue me for the amount of $ 600 7 months LATER. I refused to pay because they quoted me $ 101. So, they decided to bargain. They reduced to $ 500, then $ 468, then told me if I pay now they would only charge $ 400. I didn’t pay much attention to the staff because it’s like talking to a wall, actually, the wall understands more. Finally, they decided I owe them $ 234 or they would send my account to collections. Keep in mind, even though my insurance wasn’t in network (after the office «verified» that they were) the office was paid over $ 800 for services rendered. This place is unorganized, and a scam. They threatened to forward my account to collections to see if they can get a dime out of me. Do yourself a favor and don’t waste your time here. I wish I had Unilocaled this place before making an appointment. Everything was rushed, they just wanted to bill and get a payment from my insurance company without checking details to see if they were in fact covered. Your incompetence and greediness is not my problem. Deal with your mistake of billing and quit harassing me.

Dr. Lem is the best oral surgeon. My husband had 5 implants done at his office. His expertise and care are way above any other oral surgeon we talked to, and we talked to a number of them about having implants done before we found Dr. Lem. The implants were done perfectly. My husband’s bite is prefect now. The price we were quoted is the price we paid. The office is not in a new building and it’s not a fancy office. The staff was extremely kind and helpful. My husband was nervous about getting the implants done and Dr. Lem and his staff made him feel completely comfortable. The after care my husband received was amazing. The bad reviews on here must be fake. Dr. Lem and his staff are the most professional and knowledgeable you’ll find in the area. He is the best in his field.

I had a wonderful experience at Dr,.Lem’s office. The staff were very kind and compassionate. Dr. Lem was amazing and he spent at least 30 minutes going over what procedures are necessary. He was very thorough and never did I feel pushed to finish so he could be on his way. It was a very positive experience and I am very grateful to Dr. Lem and his staff,.

My experience at Dr. Lem’s was over all great! I was referred by my orthodontist to get my wisdom teeth removed. The assistant staff were all really nice, especially Heather who made sure I was comfortable before I was put under. She by the way was the nicest assistant I’ve ever met. The surgery went without a hitch and I woke up in a chair with a blanket and a nice heater. I was overall very comfortable and very happy with the procedure. I got my stitches removed the following week and that was quick and painless. As a whole I was very satisfied with my experience here although it’s a bit pricey.

I even dnt want give 1 star. This place is HORRIBLE. DNT WASTE your money and time there. First of all, I totally agree with the first two people writing reviews. The front desk women terrible, they even tell me different prices. It’s all about Scam. BE AWARE they tell you one price, but when you pay they ll charge different prices, way too much beyond what they told you at beginning. 2^nd I paid more than 100 dollars consultation fees to Dr Lem, he even not spending 5 mints to explain. He took only 1 mint and left. 1 mint =100 $, that’s such an easy money for him. But not worthy for you at all. An caring doctor not spend 1 mint to patient. Once again, DNT GO there. EVERYTHING is OVERPRICED. Find a doctor who really caring but not all for money. Find one be there for your teeth. good luck. Hope my review helps you.

I loved my experience here! I didnt wait long at all when I got there and I was in and out for my wisdom teeth extraction in about an hour including xray! Dr. Lem was very knowledgeable, answered all my questions, and was appropriately humorous! Everything went smoothly :)

I’m surprised at all the negative reviews on here for Dr. Lem. I was referred to Dr. Lem by my dentist since I had to remove a wisdom tooth out.
I remember the nurse telling me that this would be the best nap I’ve ever had. The next thing I remember was waking up and seeing the nurse next to me. I asked her when were we going to get started and she informed me the procedure had already been done. It was indeed the best nap I’ve ever had.
I think Dr. Lem did a great job because I didn’t swell up nor was I in any pain what so ever. I returned back a week later for a check up and everything was great. I was back to eating solid food and using mouth wash again. Yay!
I’ll admit the procedure was a bit costly. I paid cash and spent a little under $ 800 for 1 wisdom tooth. They told me mine costed more because of how impacted it was and not to mention I was put to sleep. Best decision ever! since I don’t endure pain well.
They do accept credit cards but will give you a discount if you agree to pay in cash. They have a parking lot that they share with other offices so at times it maybe difficult to find a parking spot.

I DO NOT recommend Dr. Lem either. My daughter needed her wisdom teeth extracted so we decided to use Dr. Lem because his office is conveniently located close to our house. However, I don’t recommend him because he doesn’t take the time to assure his patients that they’re in good hands– A brief 5 minute or less consultation where he just walked in, spoke a few words and left costed me $ 100 and when my daughter’s operation was done and she was in the recovery room, Dr. Lem was nowhere to be found and didn’t bother coming to talk to my daughter to tell her what to expect, how to take her medications or anything! A week later we went back to have my daughter’s stitches taken out and not suprisingly, once again Dr. Lem was not there. One of his assistants took the stitches out and that was it. The operation went fine with no complications whatsoever but the overall care for his patients is terrible. Definitely not worth the $ 2,000 spent.

Don’t go here. I know why there’s no reviews on him. Most of his patients are older, non-​englishing speaking patients.
The staff are a bunch of ravenous used-​car saleswomen. They are ready to use every kind of scare tactic to get you to spend money on their I-​Cat xray or panoramic x-​ray system. They tell people that you have to get one, if you don’t you might get so sick that you will end up in the emergency room spending more money. I heard the office manager tell another patient that when he needed an extraction and brought in his x-​rays from his own doctor’s office. They said it was infected and probably infected to his sinus. Thing is, they said they would still pull the teeth but that they would treat it with different antibiotics… come on, why not just treat him with the better antibiotics anyways? They did the same to me. When I saw the dentist for an implant, he explain his hack job to me impatiently, gave me a quote and then hurriedly left the room. Then they came in with my developed x-​ray, the one they forced me to take. THE DOC DIDN“T EVEN NEED THE X-​RAY TO GIVE ME A QUOTE. AND any good surgeon would not have to rely on an I-​CAT x-​ray to perform an implant — they should just do a complete flap removal.
AVOID THIS PLACE AT ALL COST… it’s in such a run-​down building that if there was an earthquake, the building would most probably collapse.
AS FOR THE STEM CELL IMPLANT??? Why take bone from your wisdom area — if there is any bone there if they’ve all been pulled and then HAVE TWO SEPARATE HEALING SITES after the surgery??? Then you have double the amount of worry when it comes to healing and infections, two sites of PAIN, not to mention the higher chance of nerve damage with two sites compared to one.
Trust me, you’ll want a doc who cares about you enough to want to talk to you before, during, and following-​up after a surgery. Certainly not Dr. Lem who couldn’t spare more than 2 minutes of his precious time.
And be super wary about 5 star reviews written by people who have only 1 REVIEW — come on, how obvious can it be that it’s fake???
BTW, my implant is now done and such a success! Read my other reviews if you are interested in which doc I finally chose! (after months of searching!)
