Changing any information for your medical alert systems account is easy. All you have to do is give us a call… We will ask for either the home phone number of the person using the system or your account number, and then we can get in the medical alert account and change whatever you need. It's good to look over your personal list of contacts a couple times a year. People's lives change suddenly. You may forget that your neighbors who have moved are still on your list. It's important to always have the most current information with your medical alert systems account - this of course includes your address information, phone number, any changes to your phone service, and your billing information. Once you are a customer, give us a call a couple times a year just to go over your medical alert information.
[Read More...]When you order our system you get your choice between the medical alert necklace and the wristband. Now, most of our customers already have a preference and would be more comfortable wearing one or the other with their medical alert system. If you don't have a preference here are a few things to think about: Do you wear necklaces or a watch already? Perhaps you are already comfortable wearing something around you neck. You might choose the medical alert necklace then. Or maybe you feel like the necklace button would get in the way of the other necklaces you wear. The wristband may be for you. Ultimately it is your choice! Whatever you are more comfortable wearing everyday is the best choice for your medical alert.
[Read More...]In an industry riddled with annoying and frustrating sales calls we know how very important it is to be different. We consider it disrespectful to call seniors at home, interrupt their days, and try to pitch our medical alert service, and we know you would feel the same way. Not only do we not make sales calls, we don't call you to follow up even after you call us and express interest in our service. The decision is yours. And you would need to call us back if you have any follow up questions or want to place an order. We encourage all seniors and their families not to support the ongoing cycle of aggressive sales calls in the medical alert industry. If you are getting a follow up call from a company and you didn't even leave them your phone number, don't order with them!
Lately, lots of seniors across the country have been getting called by a company called "Senior SafeAlert." Their website is SeniorSafeAlert.com, and when you try to call the number on their website, it goes to their voice mail. Due to the similar name, we have received calls from angry seniors who have confused our company with Senior SafeAlert. It is important to note that Senior SafeAlert is a different company than us, and we do NOT make any sales calls.
What can you do to stop these annoying sales calls from that company? There are a few important question to ask, so don't hang up! Who is calling? What is the name of this medical alert company? What is their website? What is the name of the person you are speaking to? Where are they calling from? Write down the caller id that this call came from. Any and all information you can gather will help stop these robocalls! Beyond asking them to put you on their Do Not Call List, you can file a complaint with the Federal Communications Commission at: https://esupport.fcc.gov/ccmsforms/form1088.action?form_type=1088B … Doing so will help stop those calls and help protect seniors across the country!
[Read More...]One fall can sometimes mean the difference between healthy later years and ongoing health problems. Sometimes in this great country of ours preventative medicine is a little overlooked. Getting ahead of a problem before it can really improve your quality of life though - especially with dangerous falls that seniors sometimes have! A lot of seniors end up choosing to use an elderly monitoring systems, or medical alert, only after they have already had a serious fall. It's important not to wait to long. It’s never too early to plan for a long happy life living in the home that you love so much. Home is where you should stay, and taking preventative measures like using an elderly monitoring system will absolutely help.
[Read More...]Its important to always think about your situation and what you need - sometimes your health can change awfully suddenly and its good to be prepared. Seniors who live with family are often less likely to feel the need to have a medical alert in their home. While its nice to have family around through part of the day, chances are you spend a number of hours each day alone. Emergencies can happen at anytime. This could be when a family member is around and able to help or it could be when you are alone. You could have a fall when it is late at night and everyone else is asleep. If falls or medical emergencies are a concern, don't wait to get yourself protected. A medical alert helps immediately to get you help instead of waiting to be discovered by a family member or hollering and hoping someone hears you. Whether you are alone or home with family all you would need to do is press the medical alert button to get the help you need. It's a smart idea for all seniors.

"I'd like to take a moment to commend one of your employees, Casey… Casey was very patient and took me through step by step of what to plug in where… My mother is 89 and lives alone. Your service is vital to her staying in her home with some level of independence.
Casey is an example of a caring, knowledgeable and patient customer service representative. He portrayed your company in a very positive manner. I hope you are proud to employ (and reward) such a wonderful person."
Sincerely,
Jeannine L.
Maryland is a wonderful place to be. We have supported so many health agencies and fire departments in Maryland with the Vial of Life program and we have 100's of medical alert clients throughout the state. I had the best Crab legs and ate at some great restaurants. I was also lucky enough to catch a Ravens game. I found I always liked the people in Maryland.
I spent a day at the Baltimore Harbor recently at the recommendation of one of our medical alarm system customers. After an afternoon at the Aquarium, I had some great salmon at Rusty Scupper. What a fun city!
Last summer I drove through Pasadena on my way into Balitmore. As is my custom, I had an opportunity to visit 2 of our personal medical alert system clients. I had great chinese food at Lucky House near Riviera Beach. What a nice community you have there! What a lovely group of people and senior citizens in Maryland.
I have heard a lot about Columbia. Its interesting that its separated into different villages to keep the small town feel. I hear that Merriweather Post Pavilion is a neat theater - I would love to see a performance there! What a unique place!
We service customers in all of Maryland's cities. If you don't see your city or town listed rest assured that we still do cover it. We cover the entire state of Maryland including all rural areas…
