Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

NEVER
DR LAMBERT'S STAFF IS TERRIBLE. THEY'RE STANDARD PROCEDURE IS TO NEVER RETURN TELEPHONE CALLS. MY LAST EXPERIENCE TOOK 3 WEEKS AND FOURTEEN4 LEFT MESSAGES FROM ME, AND FOUR MESSAGES FROM MY CARDIOLOGIST SURGEON BEFORE THEY RESPONDED, AND ONLY AFTER THREAT FROM MY SURGEON; AND THEN THEY SENT THE WRONG REPORT. MY LATEST ONE FOR A PRESCRIPTION HAS TAKEN FIVE MESSAGES WITH NO RESPONSE. IT IS OBVIOUS THAT DR LAMBERT HAS LITTLE CONCERN FOR HIS PATIENTS.

Get ready to wait
If you have time to waste and enjoy sitting around, this is your place. I went twice and won't be going back. First appointment took 2 hours for about 10 min of face time. For the second appt I waited an hour before being told I would have to reschedule due to broken equipment.

Your heart health isn’t important here
No one answers phone. Messages are never returned. Wait time is hours. You have to physically go to his office to make contact. You would think Dr Lambert would care about his practice and how his staff represents him but he doesn’t care. Go elsewhere!

I find Dr. Lambert to be a very good doctor. He has helped me on multiple occasions and takes all of my concerns very seriously. Getting a call back from his office staff is sporadic and from the office manager, well it never happens. If you want an excellent doctor, choose him. He has called me himself when I needed medical help and/or advice. If you need help with paperwork, you may need to go into the office. I don't think it is fair to rate him and his office staff together. I find the people at the front desk to be friendly, but unreliable for callbacks. I don't think you could find a better cardiologist. Since the question is would I recommend Dr. Lambert, the answer is absolutely! Therefore I can only give a five star rating.

Poor Experience - Dr. Lambert is a good doctor and takes time with his patients. However, the office is poorly run and the office manager schedules so many simultaneous appointments that the wait time is hours. There is no respect for your time. So if you have better things to do than wait for hours to see the doctor - find another.

I have decided to leave Dr. Lambert after many years with him. The reason is that I needed a cardiac clearance for surgery from another doctor and nobody on his staff would return my calls for help. Four days and four polite but urgent messages left on his nurse hotline resulted in not one returned call, despite the greeting promising a return call by the next business day. My urologist finally was able to get his clearance at 4pm the day before the procedure. Meanwhile I was stressed, not knowing if my heart could reliably withstand a general anesthesia. I never want to go through that again.

If being able to reach a nurse for urgent advice is important to you, consider that I left messages for four consecutive days on the nurse's hotline and never got a call. I needed a cardiology release for a pending surgical procedure. I was stressed and unable to get ANY response from his office. My surgeon's assistant took up the cause and finally received the release literally two hours before the operation (after trying for over a week). I was left hanging (and fasting), not knowing whether the procedure would proceed or not. No excuse for this when his nurse's phone greeting says they will return all calls within one business day. I will be changing cardiologists after many years with Dr. Lambert because I feel that access to a health professional within 24 hours is not something I can sacrifice.

Dr.Lambert is a great dr, my mother has been coming to him for years. However his office manager Danielle is a joke I have never met anyone more rude in my life. she has no idea how to run an office, it makes me think a little differently about Dr. Lambert that he allows her behavior. she bad mouths patients, has a dirty mouth constantly cursing about something, treats the check in and check out girls like complete garbage. shes the only one that can make a double booked appointment, then you wait 3 weeks to even get that when the dr wants you back in 2 weeks. the last 3 times we were in there shes to busy socializing on her cell phone( I've been a nurse for 22 years and I know that's a hippa violation) sexual comments that come out of her mouth towards the male medical assistants in there.. I CANT EVEN BELIEVE DR LAMBERT ALLOWS HER TO WORK IN HIS OFFICE AND BE AN OFFICE MANAGER AT THAT. She needs to be let go then I will consider bringing my mom back in again.

Dr. Lambert is knowledgeable for sure and got me to a position of stability with my heart, but there are a lot of issues regarding follow-up by staff, communication to client (myself) and overall office etiquette. I have never directly been able to communicate with him outside of office visits. That leads me to why I am reviewing his staff more than Dr. Lambert. After 7 minutes on hold, the office manager who was a compassionate as a frog in boiling water came on with an attitude that led to arguing back and forth regarding lost or not received test results which are normally available by computer by logging into the hospital portal. To have to argue about no communication of why a procedure was cancelled last minute a week before, lost test results that were supposedly read, and how people are satisfied with him and I had had enough. I ended up getting a second opinion and immediate results in one day which says it all about his support team.
