Patient Comments (24)
Absolutely the worst experience I've ever had with a doctor. No communication from staff, ancient and dingy facilities. Not only were they over an hour late to see me, I had to uncomfortably wait in a procedure room for almost an hour after that. I finally just redressed and removed all their equipment and walked out and got a refund for copay.

Dr.Nimish Thaker Is the worst, the most irresponsible unethical doctor that I have experienced in my life. In 2015, Dr. Thaker left me abondoned with my bladder full of water, under serious pain and stress with no referal to another physician in the group to help me. When I under pressure went to the receptionist for help, instead of helping he pointed his finger to my phace saying "you have psychologycal problem, you get out of here". Call me for the detail. Non space to explain here.

I had a medical procedure done by Dr. Thaker in his office. I was extremely impressed by his skills and his willingness to educate me prier to the procedure, how to prep for the procedure, and what to expect following. Dr. Thaker had a medical student with him, but he himself did the procedure. After the procedure and following the recovery there were no surprises! I can't even see the incision site three weeks following. Office staff could use a consultant to bring them up to speed though.

Dr. Thaker has been my urologist for over 3 years now. He saved my life after performing laparoscopic nephrectomy surgery on me. He remained extremely caring and supportive throughout my treatment and surgical procedure. I truly believe he dedicates himself to offer the best healthcare he possibly can. His wait times are a bit long, but his calm and caring demeanor, and helpful staff are worth waiting for. I would highly recommend to those in need of an excellent Urologist.

When i was diagnosed with prostate cancer it was from a referral from my PCP, with much apprehension on this endeavor i soon found that Dr. Thacker was the perfect one to get me on the right tract. His matter of fact manner was reassuring to me as i'am not one to beat around the bush. though the decisions on a course of treatment were mine, Dr. Thacker was receptive and supportive. everthing in this process aside from the emotional was very professional. Thank you Dr. Thacker and staff.

Dr. Thaker has been my Dr for over six years with great results. He figured out the cause of my kidney stones and prescribed the correct medication to solve my problem. I have been stone free for five years.

I cannot overstate how thankful I am for the care and treatment I've received and continue to receive during my bout with prostate cancer. Dr. Thaker performed a Prostatectomy on me in Sept 2015. The surgery was difficult but Dr. Thaker proved to be very skillful surgeon. The surgery was successful and a year later I have a PSA level of ZERO. I consider Dr. Thaker an excellent doctor and a credit to his profession. Dr. Thaker's office staff are always courteous and always willing to assist.

Dr. Thaker is my urologist for about three years and he did my photoselective vaporization surgery in May, 2015. He is a good urological surgeon! I am still on medication but I am feeling better. My primary doctor recommended him to me because he is one of the best in town and I agree! He is very sincere and honest in dealing with me and I really appreciate his compassion, too. He answered my questions and give the best solutions to my problem. He deals with me professionally. Thank u Dr.!

I have kidney cancer and him and his staff have made everything easy for me to get thru this.

Dr Thaker performed a vasectomy for me. The procedure was quick and painless, and Dr Thaker gave me all the information I needed both prior to the procedure and after care. I am very pleased that I chose to go to Dr Thaker for my procedure and would highly recommend him to others.
Corona, CA |
Dr. Thaker has been treating my prostate problems for several years now. I was previously being seen by another urologist with no improvement in my condition so I decided to find a new urologist. I looked on line and was impressed by Dr. Thaker's credentials and training. He is straightforward and honest and does not recommend or perform unnecessary treatments. I would not see any other urologist.
in Ontario, CA |
I'd definitely recommend Dr. Thacker because he is such a kind professional respectful man who always takes his time explaining to me everything that is going on during every visit. He's so respectful and mindful about how I'm feeling and that means a lot to me

Dr Thaker taking care of my elderly father for many years with kindness and practical approach. He will not do any unnecessary procedures for financial reasons but discuss any issues that can cause pitfalls. He approaches patients like they are his own family. Now that he has a new practice, I felt the need to give a review in support of this great doctor - Keep it up!

Dr. Thaker, we want to thank you for taking care of our health problems. We are blessed to have the best Urologist taking care of us. God bless you.
in Beaumont, CA |
My first visit was terrible because we've waited for two hours before we were called in. But everything went well when I met Dr. Nimish Thaker. He is very skilled and kind doctor. He explains to us the procedure in a layman's terms so we can understand thoroughly. Definitely I will recommend Dr. Thaker to my friends and families!
in Riverside, CA |
Dr. Thaker is a knowledgeable and experienced doctor who really cares for his patient. I fell very comfortable to discuss with him my medical issues. I have been visiting Dr. Thaker for my checkups for the past 8 yrs. and i highly recommend him.

In 2013, my husband was diagnosed with a rare cancer, with high incidence of recurrence. Dr Thaker performed an intricately difficult surgery removing a kidney, ureter, and portion of my husband's bladder. With a high incidence of recurrence continued screening/testing is necessary and performed and monitored by Dr Thaker. Dr Thaker is a matter of fact, no-nonsense, expert urological surgeon. I attribute my husband's quality of life to the superior skill and expertise of Dr Thaker.
in Riverside, CA |
Upon finding a mass on my husband's kindey, Dr Thaker's office was able to get us in the very next day. He was very professional and informative about our options. His years of experience along with his confidence and competence was reassuring enough. His staff was helpful but Imelda went above and beyond to ensure everything was in order and authorized for surgery. His surgical skill and in-hospital management care were outstanding. We would highly recommend Dr Thaker for any surgery required.

Dr. Thacker, is a person that is in THIS business for ONE REASON!!! It has NOTHING TO DO with MEDICINE, OR HEALTH, OR THE WELL BEING OF ANYONE, but himself and his family!!! HE IS PATHETIC! HE SHOULD NOT BE IN MEDICINE! Period. He treated MY SON! THANK GOODNESS, we found him a REAL DOCTOR, who got into this field for the right reasons! MAY HE REAP HIS OWN REWARDS, based on his actions to his patients! :( I'VE WORKED FOR MANY DOCTORS, in my profession! I know TWO, exactly like THIS! PATHETIC!
in Banning, Ca |
I went to him to seek help. Instead he gave me the run around going to other doctors when he new that there was nothing they could do for me. He said i had to see for myself. What is he my parent? I also was stuck in traffic and i called to tell them i would be a little late but on my way and they decided after 5 min on the phone that i would have to reshedule. All i have to say is that he does not show concern for his patients. I would not recommend him to anyone. He was a waste of time and gas
in San Diego, CA |
The experience was horrible. The office was overrun with patients waiting to be seen. Our appointment was scheduled for 10:30AM and he did not see us until 11:30AM. Dr. Thaker was reluctant to answer our questions, The office was VERY messy with patient files piled up everywhere in the offices. Staff were unfriendly and not helpful.
in Rancho Belago, CA |
This doctor exhibits a lax attitude towards patients, and appears to only care about making money. He rushes through exams with patients and treats them like cattle. Also, he makes patients wait for hours after their scheduled appointment time, just because he is in surgery (a fact not made known until patients arrive at the office). Poor service, frustrating experience, not recommended.

1.The dr. was 2 hours late.2.We were sent to an exam room to wait another 15 minutes.3.Doctor arrived, rushed,sat down, shuffled through papers,no greeting, no eye contact, just straight into it, RUDE&UNCARING.4.Didn't seem to like my questions.5.He asked ME what dates dad was put on 2 medications:I told him to look in the documentation.6.He dropped the file & walked out (like a diva),leaving my 83 yr. old dad holding his catheter. He'll get a letter of complaint to the medical board. STAY AWAY!
