Mark Sanford: A Life-Changing Career

By James Florence, Diamond Certified Resource Reporter

WALNUT CREEK — Mark Sanford may have come into the audiology field by chance, but there’s nothing coincidental about the impact he’s had during his three decades of professional practice. “When I first went to college, I wasn’t sure what I wanted to do,” he remembers. “At one point, I took a class on communication disorders, which is where I first encountered audiology. I found it interesting on both a medical and technological level, and I also appreciated how versatile it was: you could work in a hospital, have a private practice, do research or go into education. With all of these different avenues available, I decided to stick with it and see where it took me.” Ultimately, Mark chose to go into private practice, where he’s been helping people preserve and improve their hearing ever since.

Today, as president of Better Hearing Center, Mark says his favorite part of his job is the opportunity to change people’s lives. “I love helping someone who’s suffering from hearing loss and reconnecting them with their loved ones. It’s not unusual to have a patient come to tears after being fitted with a hearing aid, because they’re suddenly able to hear and communicate clearly again. It just doesn’t get any better than that.”

A resident of Carmel (where he lives with his wife, Pam, and their daughters, Isabel and Natalie), Mark expresses his appreciation for life in the South Bay Area. “The quality of life is great here. The people are wonderful, and I think the technological advancement over the last 30 years has made a big difference. If you find a better place to live, let me know and I’ll move there!”

Outside of work, Mark enjoys activities like golf, gardening and travel, but most of all, he likes spending time with his family. “On a typical weekend, my family and I might go on a hike or head to the beach. Right now, our lives revolve around what the girls are doing, which includes activities like Irish dance and musical performance. They’re involved in a lot of things.”

In regard to his professional practice, Mark believes in taking a team approach rather than trying to be a one-man show. “I think my staff and I share the same passion for changing people’s lives, so we’re all on the same page in terms of our commitment to quality care,” he says. “Instead of micromanaging my staff, I give them space to make decisions. Certainly, the buck stops with me, but at the end of the day, we’re in this together as a team.”

When asked what his future retirement might look like, Mark says he’ll be intentional about staying active. “I’ll probably do a lot of the same things I do now: go for runs on the beach, play golf and hang out with my family. I think it’s important to stay active, especially in retirement—you need to have a reason to get up each day.”

Ask Me Anything!

Q: What’s your favorite sports team?
A: I have a few: the San Francisco Giants, the Golden State Warriors and all of the teams at Stanford University, which is where my wife and a lot of my family went to college.

Q: What’s your favorite thing to do on a rainy day?
A: Read a book.

Q: Do you have a favorite book?

What To Ask In Person
What to Ask in Person at Santa Clara County Hearing Aid Centers

When you have finished interviewing hearing health personnel on the phone, narrow the field to your choice of the best hearing aid centers in Santa Clara County for you.

Look for a local hearing health care professional that will help you select hearing aids with appropriate features. This professional can offer recommendations and advice to help you find the hearing aid that will work best for your hearing loss and your lifestyle. No hearing aid style is better than any other hearing aid. You must simply choose the one that is right for you.

The hearing aid provider will consider:

  • lifestyle needs
  • hearing aid functionality and cost.
  • your ear anatomy
  • manual dexterity
  • your particular hearing loss
  • cosmetic preferences

Don't go alone for this interview. Bring along a friend or family member for support. It's likely that you will be presented with a lot of information and options, and two people will usually hear and remember more.

Here is a list of possible questions:

  • Is the hearing assessment included in the price of the hearing aids or is it separate?
  • Is there a trial period?
    Many times hearing professionals will offer a trial period, so you can try a set of* hearing aids for 30 to 60 days. During this time, the hearing aids can be returned for a refund. Also the hearing professional can adjust the hearing aids to give optimal comfort and sound, so you can know what it is like to wear hearing aids daily.
  • Is financial assistance available for purchasing a hearing aid?
    You can sometimesget government support and insurance coverage to help with the cost of hearing aids and hearing evaluations. Make sure to ask your hearing professional for more information.
  • What type of hearing aid does the hearing professional feel is best for your type of loss?
    Remember that mail order hearing aids won't take into account the your type *hearing loss. You should avoid these offers.
  • What kind of add-ons can I get? Never feel pressured into buying something you don't really need.
    Those extras come at a price, but there are benefits. For instance, directional microphones help you in noisy places. Tele-coils assist with phone conversations, and feedback cancellation keeps the aid from squealing. Wireless technology will assist with cell phones use and televisions. Just remember to consider which hearing aid functions you really need.
  • Ask for a contract that explains everything that you are buying.
    Include the make and model of the hearing aid in the contract. Know the exact price and the trial period. Also get the warranty information. Set the dates for the follow-up visits. Usually there are three or four visits in the first eight weeks.
  • What kind of training is given with the hearing aids?
    Just fitting the hearing aid in your ear is not all there is to buying a hearing aid.. You actually hear with your brain. When you get hearing aids, your brain does not know what to do with the sound. You will need aural education and rehabilitation. Some of this training can be done at home on your computer or through group sessions.
  • Do you recommend one or two hearing aids for my hearing loss?
    Hearing professionals typically recommend wearing two hearing aids for people with a hearing loss in both ears. The name for this is binaural fitting. Also two hearing aids help improve hearing in noise, and improve sound quality and clarity. You can ask for the pros and cons of one or hearing aids.

  • What To Ask References
    What to Ask References for Hearing Aid Centers in Santa Clara County

    It is smart to select a Diamond Certified hearing aid center in Santa Clara County because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a hearing aid center in Santa Clara County and the greater Bay Area, you can have confidence picking a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

    If you can’t find a Diamond Certified Hearing Aid Center within reach, you’ll have to do some research on your own. If you do, it is a good idea to call some references provided by your doctor. Remember though, that references provided to you by the doctor are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

    When calling references on your own, specifically ask for a list of the company’s ten most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

    Following is a list of possible questions for you to consider when speaking with references about the hearing aids:

    • Were you happy with the hearing aids the hearing center provided?
    • If there was a problem with your hearing aids, did the Santa Clara County hearing aid dispenser honor the warranty?
    • Did the local hearing aid center offer payment plans that worked well for you?
    • Were you confident of the hearing doctor’s recommendation of the type of hearing aid?
    • Are you happy with the training and aural rehabilitation you are receiving to use the hearing aids?
    • Does the staff take time to make sure you are comfortable with your hearing aids?

  • Review Your Options
    How to Pay for a Santa Clara County Hearing Aid

    The Diamond Certified symbol has been awarded to companies that scored Highest in Quality in an accurate ratings process.

    An important consideration of hearing aids in Santa Clara County is the cost. Hearing aids are quite varied in price, so before deciding on the top hearing aid to buy in Santa Clara County including in the major cities of San Jose, Sunnyvale, and Santa Clara, there are some important things to consider.

    Medicare currently will not pay for the price of hearing aids, but they will pay for the exam to get hearing aids. Some private insurance companies will also do this. If a physician prescribes an audiologist hearing test, Medicare will pay for that. Private insurance companies may pay for portions of hearing aid costs or may not pay anything. You will need to check with your insurance to find out what your coverage is.

    Some of the following questions should be considered when buying hearing aids?

    • What are the billing practices of the hearing aid center?
    • What payment options does the facility offer?
    • Can I obtain financial assistance for a hearing aid?
    • What is the quality of the staff of the center?
    • Do you assist veterans in getting help with hearing aids?
    • Does Medicare provide any benefits for this service?

  • How To Work With
    Learning to Adjust to Wearing New Hearing Aids

    After working with a Santa Clara County hearing aid center in selecting hearing aids, you will begin the transition to feeling at ease wearing them. This will take some time. At first, it will be helpful to use the hearing aids at your home or in quiet surroundings. You will learn how hearing aids magnify the noise in the background. That makes settings, like restaurants and church, seem very frustrating. Remember to ask about aural rehabilitation. Rehab will assist you with the frustrations of learning to use hearing aids.

    Other issues may appear also. New hearing aid users will find their voice sounds very loud or maybe plugged up. (That is an uncomfortable feeling that is like putting your fingers in your ears when you are talking.) This can be a problem with all hearing aids; however, it is a bigger problem with the type of hearing aids that fit deep in the ear canal.

    Problems may arise when you find that your cell phone is not compatible with your hearing aid. Usually the hearing aid will cause a buzzing sound during usage. To stop this problem, you can use a hearing aid with Bluetooth wireless technology. With this, you won’t need to raise the phone to your ear.

    Your hearing aid provider can adjust the hearing aid by drilling a small hole in the ear mold. Or you can change to a different hearing aid style. The open ear hearing aid might be better for you.

    Feedback might be a problem. This is where you have the high pitched screeching sound from the hearing aid. Learning to adjust the hearing aid correctly should solve this problem. This can be taken care of in the training classes.

    Tips for Hearing Aid Users
    Some tips for hearing aid users to follow are:

    • Thoroughly read the hearing aid manual. Reading this will help you get the best use from your hearing aid.
    • In theatres, conference halls and churches, you will want to sit near the center of the building. That is the spot with the best acoustics.
    • You will want to sit close enough to a person speaking so see his/her face, but don’t sit too close.

    • Ask your hearing aid center if you should call to check on the progress or if he will call you with updates.
    • When the Santa Clara County hearing aid center contacts you, return calls promptly to keep the hearing aid contract on schedule.
    • Be clear and upfront with the hearing aid professional and/or the staff. Let them know what you want from your hearing aid, the long-term outcome you're expecting and specific ways they can satisfy your expectations.

They feel frustrated because they feel others are mumbling, and they must ask often people to repeat themselves. Some will find that others mention how loud they are listening to the radio or television. If hearing loss is suspected, you should have tests done to make sure it is diagnosed and treated properly, and also to confirm that isn’t another disease or ailment.

Q: What are the various types of hearing aids?

A: Behind-the-Ear (BTE) – This hearing aid will sit behind your ear. It is attached to an ear mold that fits  inside your ear with tubing. An ear hook is used to fasten it on the ear. The molds are custom made for each user.

In the Canal (ITC) and Completely in the Canal (CIC) – With ITCs and CICs, the entire hearing aid fits inside the canal. CICs are extremely small in size, and nearly invisible. ITCs are usually larger.

Disposable hearing aids – You can choose a disposable hearing aid. They have a built-in battery and after a certain amount of time or use, the person will replace the whole hearing aid.
