Merry Christmas & Happy Holidays!

Hi Dr. Mikhael,
I just wanted to tell you that I am still doing great. I am so happy my RSD is gone. I played catcher on this softball team this year. I wasn’t able to play softball for 2 years because the pain of RSD. I am so thankful that you were able to help me. Have a great summer!

Dear Dr. Mikhael
Since October 2003 you have decreased my pain from a 9 to a 3-4! That is Heaven sent! I see that you truly care about me and the rest of your patients. You are a very caring king, generous, compassionate and understanding doctor. You will forever be in my thoughts because of all that you have done for me (and my family) and continue to do! I can’t thank you enough for sharing your talents with the world! You should be very proud of yourself.

May the Holiday Season bring only happiness and joy to you and your loved ones.
You are an amazing juggler. I know it’s your job to make arrangements for procedures etc. but you do it with such patience and extreme pleasantness. SO many thanks for being there doing a tremendous job.

Dear Dr. Mikhael,
I wanted to let you know I had my back surgery Dec 13th with Dr. Ceverha. I am doing great. This is to thank you for all of your loving care that you gave in the past few years. I only wish I had done it sooner to advoid all the shots I had to get. Your care is never forgotten and if I ever have to go through this again, I will only want you to be my doctor. Your experience shines.

Dear Dr. Mikhael
My mother, Bonnie, who has been seeing you for the past 5 or 6 years, has been advised by Healthcare Partners Medical Group that you are no longer a contract provider for the Long Beach area. She cannot, therefore, continue to see you under her present insurance coverage. She is very sad to receive this information, as am I. From our first visit with you to this very day, you have been the most caring and professional of any of the healthcare providers she has seen. She has received excellent care from you and always looked forward to seeing you because of the dignified, friendly and caring way that you have treated her these past several years. Your prompt attention to her needs has been greatly appreciated. You have really become one of the family and we will miss you greatly.
Over the past 15 years, I have seen the level of caring among healthcare providers deteriorate and it gives me great hope for the future when i meet someone of your character. There is no doubt that the medical profession and the country in general, needs more men like you! Take care of yourself and god bless you.
Most Sincerely,
Richard and Bonnie

Dear Dr. Barreto and Staff,

My wife passed away on Saturday, Jan 30, 2016 at Hoag Hospital in Newport Beach. Her name may appear as _____________ in your records because that is how she was identified for Medicare Purposes. As a 14-year lung transplant patient, her body was unable to recover from the trauma of abdominal surgery necessitated by a sudden and completely unexpected bowel obstruction on 1/19/16.

My family and I want to express our sincere appreciation and gratitude for the health care you provided for her over the long struggle she experienced with pulmonary difficulties. We wish the best of health and well-being to all of you.


To Dr. Barreto

To Dr. Messiha and all of the Pain Clinic Staff,

Thank you for your kindness, and of taking good care of me.

To Dr. Messiha and all of the Pain Clinic Staff,

Dr. Mikhael,

I call her my mom. I am so happy that you have and are practicing medicine.

Good Afternoon Zally and Dr. Mikhael,

(Zally, I don’t have Dr. Mikhael’s email. Could you pass this along to him? Thank you.)

I just wanted to write with good news. Today, just 7 days after the bilateral greater and lesser occipital Nerve RFA, I am PAIN FREE. Last night I slept a full 8 hours which I have not done in over 8 months. I have not used ANY NSAIDS or pain medicine in 36 hours. Honestly, I cannot put into words the hope and ease the work you do, how it changes lives, I awoke this morning and my first sensation was quiet. When one wakes in pain every time our eyes open, one learns to dread being awake. This morning, I laid still for 20 minutes listening to stillness in my own body. It is truly why I keep moving forward, for these little pockets of ease, of normalcy and of hope.

I realize your days, life mine, are filled with dealing with pain and the effects that pain have on peoples’ bodies and lives. I just wanted you to know, today, in this moment… what you do REALLY TRULY makes a difference. I feel like myself and can feel my own soul. That is so overshadowed when pain is present.

THANK YOU FOR EVERYTHING YOU DO AND EVERYONE YOU HELP. It makes all the difference in the world.

with a sincerely grateful heart,

Melissa M.

Dr. Mikhael & Dr. Baretto,
Our mother passed away peacefully at her home on Jan 16. As a patient of yours, she was ever so grateful for the care she received from you. Without the pain control, she would never have been able to endure her treatments and enjoy a lovely holiday season.
Sue, Rusa, Dave and families.

Dr. Mikhael,
Just a note to thank you and the girls in the office for your kindness and support. And thank you so much for honoring Dr. Ceverha’s request to give me the “family” discount. Your kindness has touched my heart. And for that I am so thankful.
I am very happy to report that my back and leg is doing much better. It must be very rewarding for you when you are able to give someone back their normal life. My son is so happy that I can do thins with him again.
Please know that your kindness and compassion will always be remembered.
You and your office and of course, Dr. Ceverha are the very best. Thank you so much for everything

Dr. Mikhael,
I just wanted to send you a note expressing my thanks for all your help. The shot I received on Friday has worked wonderfully for me. By Sunday I was feeling great. I have been able to eat without any pain! Best of all I have no longer been getting ill after eating. So, again, Thank you.

Dear Dr. Mikhael,
Its so nice to be greeted by friendly happy people in your office now who know how to smile and talk to patients.
Your patience & caring is appreciated more than you’ll ever know. And, of course, you know how glad I am to have Kris bank great move – good choice…

It is very seldom that you find a medical group that is kind and considerate. Your office staff has a great caring attitude.

Dear Dr. Mikhael,
I’m so glad that my father (Manny) encouraged me to see you for my back pain. I wanted to let you know how much better I feel. Thank you so much for taking me as a patient.

I’m so grateful, Im still purring And I owe it all to you. Thank you Pain Management!

There are no words to explain our gratitude for your dedicated long hours and healing hands. We have been blessed to come to you. Last year was the continuation of a four year nightmare; last month was the awakening from that state. To go from “ I cant remember what it feels like to have a good day” to having fruitful days; this is where there are no words. Only tears of joy.
Cindy and Tom

Doctor Messiha,
I just wanted you to know how much I truly appreciate all that you and your experience is providing me. With every procedure and every follow-up appointments with you, I find myself feeling better and in need added control of my pain your dedication to your profession has given me a quality of life in lesser pain where two years ago I didn’t know what else to do. You take time with me every single visit to listen and to hear me where other Doctors have not. I feel comfortable and for less anxious with you at the helm more so then I have with any past experiences. I know you are a person with his own life outside of your workplace and with that comes highs & lows, yet you never show anything but encouragement and your entire team makes going to the Doctor actually pleasurable. Thank you for that Dr.

Doctor Messiha, I truly appreciate you

Dear Dr. Mikhael,
I could not let any more time go by without thanking you from my heart – For the great medical are you provided through the last few years, but particularly your extreme and effective attention following my series of hospital at who in 2005-2006. In today’s medical world it is the norm for doctors to shrug and say “good luck” I was beyond fortunate that you were overseeing my pain care. I will never forget your many kindness. I am finally in the hands of good pain management md’s here in Palm Springs; without your help. Though, there would have been a gap in my care that would have been most damaging
Thank you

Dr. Mikhael,

Itss so refreshing to know there are people who really care!

You and your staff are awesome!
