Exciting Maxwell Group News


Please help us welcome the newest additions to our practice Dr. Rayette Casiano and  
Dr. YuJie Shui.

Dr. Casiano is Board Certified in Internal Medicine and has been practicing for over 20 years. Dr. Shui is Board Certified in Family Medicine and has just completed his
residency training at Kingman Regional Medical Center in Kingman, Arizona. Please inquire now regarding appointment opportunities.

Dr Medina is knowledgeable, thorough and attentive. It is important to me that she knows what she knows and when something is different than her skill set, she refers me to a subject matter expert. Some doctors aren't so wise. She is patient and answers questions, which is important to me so I can better understand my role in improving my health or getting well. I referred her to my wife, who is now her patient, need I say more.

John T. | Nov 04, 2022

Dr. P has been my doctor since I moved to Arizona 21 years ago .He has always taken good care of me. As I reach the twilight years and go through the aging problems ,like I am now, I have all he faith in Dr. as I have the last twenty one years. As he said "we're in this together" I would implore anyone who is looking for a great internist to use Dr. P. Richard C .Wiles a friend and patient

Richard W. | Nov 03, 2022

Scott H. | Nov 03, 2022

Always an excellent visit with Dr. Piette. He always listens to your concerns or questions. I am very happy to have found him available to be my primary care physician.

Scott N. | Nov 03, 2022

He took the time to listen to your concerns. Then went over all your results and provided a plan of action going forward.

Brenda N. | Nov 03, 2022

It was a pleasure to visit with this doctor, you can tell when someone cares I hope she is my doctor for a very long time Gene Turiano Sr.

Gene T. | Nov 03, 2022

Sam Bob | Nov 03, 2022

Dr Shui was very helpful in recommending a solution for a chronic knee problem. His suggestion provided almost instant relief.

Kenneth H. | Nov 03, 2022

Dr. Palanati went over my results and he's given me direction. Now it's up to me.

Thomas H. | Nov 03, 2022

I find Dr. Narayanan very kind and thorough. Doesn't rush you through your appointment.

Madelon J. | Nov 03, 2022

One of the best Dr visits in a long time.

Skelli Dedmon | Nov 03, 2022

I like the fact that Dr Narayanan is a young doctor and teaches geriatrics. He is not afraid to consult with other doctors for over all heath of the patient to provide him with complete knowledge of the person he is serving. He takes his time to consult and listen which is key for us old folks.

Joan C. | Nov 03, 2022

George Morgan | Nov 03, 2022

Becki B. | Nov 03, 2022

Steven Shockome | Nov 03, 2022

I have always felt that I am getting the best care with Dr Narayanan.

Mary M. | Nov 03, 2022

Listens and is very personable. She agrees with my own beliefs that diet, exercise, healthy exposure to sunshine, practicing a healthy mindset all make difference in health. It is through hard work and not always achievable or even curative. In which case Dr. Casiano will prescribe the correct prescription medications and if needed can also refer her patients to the correct specialist.

Willard K. | Nov 03, 2022

John Suhumskie | Nov 03, 2022

Betty Lust | Nov 03, 2022

Very interested in my health. Takes time to listen. Makes you feel confident and comfortable in his presence.

Butch E. | Nov 03, 2022

Kerry Grant | Nov 03, 2022

Dr Palnati has always been punctual with timing of our appointments, very courteous & listens carefully to our concerns & addresses them appropriately. He clearly reassures us about what test results are not of concern but on the other hand which of them need our attention to be dealt with as needed.

Lois R. | Nov 03, 2022

Just started going there and so far am very happy with the service and attention.

Bill Mosienko | Nov 03, 2022

Discussed my concerns and appreciated feedback. Physical exam and electro cardiogram done. Will schedule lab work and follow up.

Donelle D. | Nov 03, 2022

Dr. Medina, although knowledgeable, could not wait to move on to the next patient when we go to see her. She would not stay in the room and discuss how I was doing, she left and had her assistant come back. It made us feel that she didn't care about my health at all. All of this after a hospital stay for mental health issues. Very sad.

Joyce K. | Nov 03, 2022

John Dockham | Nov 03, 2022

Dr Palnati and his staff always take really good care of me!

Glenn | Nov 03, 2022

First time seeing Dr. Shui. I was comfortable. The med he prescribed is working. I’ve 24 more hours left taking this med. I’m hopeful the condition will not return.

Katherine W. | Nov 02, 2022

With out question Dr. Johnson is the best physician I've been blessed to see. He is professional, caring, un-hurried, through, attentive to detail. He honestly cares for his patients and their outcomes.

Robert Shelton | Nov 02, 2022

Quality geriatric care can be hard to come by, but my experience with the Maxwell group denies that statement. From timely appointments to great follow-up, I've had no complaints. I find it especially comforting to know that my young primary physician is fully tuned in to elderly health concerns and honestly cares about guiding and helping patients with their aging health issues. Of course, learning to say and spell Narayanan was a steep learning curve, but well worth it!

judith darrh | Nov 02, 2022

I was very happy with my visit.

Catherine K. | Nov 02, 2022

Dr. Palnati is very caring

Carolyn Schnickels | Nov 02, 2022

This is the first time I saw Dr. Casino and was very pleased. She is very competent and thorough. She answered all my questions and did not rush the visit.

DAVE B. | Nov 02, 2022

I was very impressed with Dr Shui. I saw him in the absence of MY PCP, and as a follow-up, it was obvious that he had read my chart before seeing me, which is often NOT the case. He was very knowledgeable, explained things in terms I could understand, and was very kind and empathetic. If I were looking for a new PCP, he would be a TOP PICK! I highly recommend him.

Patricia Heathershaw | Nov 02, 2022

Dr. Palnati, and his assistant Maria, truly care about their patients. We have been seeing Dr. Palnati for many years and have complete faith in him. We have always been more than pleased with his services.

Northwest Valley church of Christ | Nov 02, 2022

This was my second visit with Dr Shui and I was more than pleased with the quality of care and the whole process. He is a very good listener, offered a range of opinions going forward, and follow on plans were discussed. His MA, Amber, is also a very positive contributor to the experience in his office. Will definitely recommend him to friends and family.

Gabriella Attryde | Oct 27, 2022

Jeanie Cole | Oct 26, 2022

I had a very good experience, exceptionally thorough, & pleasant, with the tests performed. Dr. Casiano explained all to both my husband and me. I am very pleased & confident in having her as my personal physician at Maxwell, and most certainly see her as being a five star physician.

Catherine Huffman | Oct 25, 2022

Maxwell Group is a terrific medical practice. I recently was a patient of Dr. Casiano who is new to the Medicare-focused practice. (My regular PCP did not have an opening. Dr. Casiano was engaging and concerned. She listened and paid attention to me. She provided care and suggestions in a friendly and straightforward way. I recommend Dr. Casiano to anyone seeking a PCP.

Judy Schneider | Oct 25, 2022

Dr. Medina & I discussed my fall which broke my wrist in 3 places. She has suggested that since I have fallen & broken bones I should use a cane or walker. She had that ordered for me. Dr. Medina is very caring & SHE POINTED OUT MY KIDNEY PROBLEM. By doing this I am under the care of a kidney doctor. This could save my life.

Patricia B. | Oct 25, 2022

Dr. Palnati actually looks at your charts and paperwork before he comes in the room. He is very attentive to what you say and takes the time to explain things to you.
