I have used Peak Performance Plus for weight loss, and a sleep disorder. The results were extremely satisfying. I will continue to use, and refer my friends and family. Dr. Sterk was particularly helpful using Hypnosis to help me take off the weight.

Miriam Sterk LCSW C-ASWCM, was very helpful and resourceful in assessing my elderly mother for appropriate living and care arrangements. The Older Adult Global Assessment Profile and Care plan was very accurate in identifying her specific needs for care, support and placement.

After months of dealing with a denial from our health insurance company and getting nowhere, I contacted Miriam. In a matter of a few months I learned the tricks of getting a claim paid and had resolve. Her expertise of knowing the right people, professional letter writing and the correct way of even mailing letters and documents was so important. I was told by the health insurance company to fax everything. (WRONG) I was so grateful for her help and will never go through this on my own again.

Dr. Sterk helped me relieve anxiety due to my inward reaction toward outside stimulus. In only 2 appointments he has given me the tools to relax and regroup and I have not experienced the problems since! He is understanding and caring and has followed up with me to ask how I have been. I recommend Peak Performance Plus to anyone experiencing anxiety for any reason at all.

I’ve taken Dr Sterk’s class and extremely impressed. With very little practice on his techniques, my first 9 holes of golf I played I had 3 birdies in a row, simply by staying relaxed and focusing better. THIS WORKS!

Navigating the world of insurance benefits and disability can be almost impossible, but with the help of Miriam Sterk, the results I desperately needed came very quickly. Miriam understands the intricate workings of the insurance industry, and is able to explain them clearly, so that I could easily choose the best course of action for obtaining the surgery I needed, as well as my Long Term Disability. Miriam Sterk is a lifesaver, and I cannot recommend her services highly enough.

I had the distinct pleasure of working with Dr. Sterk to address some sleep issues I'd been having for years.  Dr. Sterk specifically utilized some hypnosis techniques to address my issues and he gave me the tools to use on my own to continue working on those issues.  My sleep has improved dramatically because of Dr. Sterk and the work that we did together and I am very grateful for his professionalism, compassion and kindness.  I would highly recommend Dr. Sterk.

I've been an independent Health insurance broker for the past 37 years. I was introduced to Miriam Sterk about 5 years ago who has proved to be an invaluable addition to my practice and clients as a claim advocate. 
Miriam completely understands the complexities of our (broken) healthcare system and is an incredible resource when hospitals or healthcare providers inappropriately bill , fraudulent bill, double bill and literally cause frustration and  severe anguish for individuals.
She helped me personally when I was paying an unreasonable amount of money for an emergency room visit a few years ago and helped me renegotiate (no further payments). She requested  specific detailing concerning procedure codes and when the hospital became aware that we had no intention of giving up the management relented and confirmed no further payments were required! 
Recently she helped my client reduce a $27,000 charge down to about $1,200 total out of pocket. My client called me and told me the healthcare provider said Wow the claim advocate you hired really knows what she is doing!
If anyone would like more examples of Miriam's service to the community or her professional skills please call me at 480-205-8806.

I have known both Miriam and Sam for about 8 years.
I first met them as advocates for people being forgotten by our healthcare system. Miriam and Sam have been involved in this arena for decades. As a insurance broker, I have reached out to Miriam nd Sam multiple times because of their passion and knowledge with great results.
I am a better broker because of this "Dynamic Duo".
Thank you for always being there with your help.

Miriam called me every day and sometimes more often than that to provide me with comforting, common sense solutions to locate adequate placement for my mother. Miriam provided emotional and spiritual support, as well.

Miriam’s vision, common sense approaches and always positive attitude are both inspirational and uplifting. Her wit made me laugh when I was at low ebb.

The Case for Case Management!

DO YOU KNOW THE VALUE OF HAVING YOUR OWN HEALTH INFORMATION?

To whom it may concern:

  1. I just retired as an attorney effective January 1, 2020. I’ve been a practicing attorney since 1978, most of those years doing personal injury work, and in my latter years assisting other attorneys handling large personal injury and medical malpractice cases in resolving reimbursement liens by health insurance companies against personal injury and medical malpractice seminars. For some years, I was the featured speaker at the Arizona Association for Justice/Arizona Trial Lawyers Association by far most heavily attended seminar, the annual liens seminar. I regularly dealt with healthcare providers both as treating physicians and in terms of any liens they had for reimbursement of their medical bills, as well as health insurance carriers and companies representing them to collect their lien claims.

In my law practice:

Miriam Sterk has been most helpful. A number of times in assisting other attorneys on large cases I referred them to Miriam and they utilized her services as Case Manager to assist their client. As an example, I was handling liens on a large case involving a 39  year old school teacher who was seriously injured and was a near complete paraplegic as a result of a motor vehicle accident. Her health insurer, through Arizona public schools, continued to put her off and not approve essential medical care and equipment. One instance of this is they continued to refuse to pay for wheelchair with a tube that she could blow into so she could get around. My understanding from the school teacher’s personal injury law firm was that Miriam’s advise and assistance was instrumental to obtaining approval of this wheelchair and other home medical equipment, referrals, etc. The law firm told me they continued to utilize Miriam’s services on other large cases as appropriate as well.

I recall another attorney on our trial lawyer email listserve inquiring whether anyone could help a dire situation, his good family friend was in a terrible motor vehicle accident in California and suffered massive head injury, I referred the trial lawyer to Miriam, and Miriam worked with the health insurer to quickly get the person transferred to  Barrow’s Neurological in Phoenix for prompt rehabilitation thereapy. There a number of other instances like this but I cannot recall them all.

 Miriam has frequently assisted me and my family members as well. In 2014, I had a right hip replacement. Miriam warned me that the facility would probably discharge me without referring for nursing care or physical therapy, as as my wife had passed away I had no one to care and assist me when I got home. Miriam assisted me in getting the referral and placement to a skilled nursing facility for a week. Although I was advised prior to hospital discharge that they ordered physical therapy at the nursing facility, when I arrived I found out that they had not received a physical therapy referral or order, and when they tried to get this from my health insurer it was denied. Miriam quickly appealed, made a phone call, and suddenly therapy was approved. Also, when I was discharged home, Miriam set up a home health care aid to help me for some  hours for a week until I was ready on my own. When one of my daughters had her appendix removed in 2011 and the biopsy showed a small 3cm carcinoid, Miriam made a few calls and the very next day my daughter was seen by one of the Valley’s premier oncologists – fortunately, extensive tests revealed she was cancer free. And a few years later, when biopsy of a neck growth revealed that my daughter had Hodgkin’s Lymphoma, Miriam made a few calls and my daughter was again seen by one of the Valley’s premier oncologists the very next day.

When I turned 65 the other years, Miriam discussed with me the pros and cons and benefits of Medicare v Medicare Advantage healthplans, and the various Medicare  Supplement plans, thus greatly assisting me in signing up for the best plans in relation to my needs.

In all my years of law practice as well as my life, Miriam is by far the very best Case Manager I have ever met. She is quite amazing and other attorneys to whom I have referred her, and friends, have all agreed.
