Invest in Your health

Core Concierge Health

Your Mind, Body, and Soul Deserve the Best - Invest in our Core Transformative Health Program today!

At Core Concierge Health, we believe healthcare should do more than treat illness, it should transform your overall well-being. Our approach, which we call Transformative Health, focuses on proactive, personalized, and preventative care designed to help you feel your best every day. 

Transformative Health is about shifting the focus from reactive medicine to proactive wellness. Instead of waiting until you’re sick, we work with you to prevent illness, optimize your health, and support your long-term vitality. It’s healthcare that transforms how you feel, function, and live your life. 

What Is Concierge Medicine?

Healthcare should feel personal, accessible, and centered around you. In this short video, you’ll learn how concierge medicine offers a more personalized approach to primary care, providing longer visits with your physician, easier access to care, and a stronger focus on prevention and long-term wellness. By caring for a smaller number of patients, concierge physicians have the time to truly understand your health, answer your questions, and build a meaningful partnership in your care. Watch to discover how concierge medicine works and the benefits of a more connected, patient-focused healthcare experience at Core Concierge Health.

Have you decided to invest in a 401k or real estate because planning ahead to secure your financial future is a priority for you?  Possibly you have made other financial commitments such as a car or opening a college savings fund?  What about investing in your health? Your health is your greatest asset, are you investing in it?

Investing in your health now is a proactive step towards a happier, healthier life that will reap many rewards over time.  Taking control of your health is a concept lost in modern society because the current medical system is designed for medical professionals to focus on the volume of patients that come through their practice.
Insurance companies are becoming the main decision makers which requires most doctors to see 30-40 patients per day to meet their overhead expenditures.  It's created a patient care pandemic where studies show that the average doctor's appointment takes about 2 hours of time, but only 15 minutes is actually spent with the doctor.

You owe it to yourself to INVEST in, not neglect, Your Health.

The mission of Core Concierge Health is compassionate care centered on You.

Your Core Concierge PHYSICIANS

At Core Concierge Health, our physicians believe concierge medicine restores what healthcare should be—time, access, and a true partnership with patients. By caring for a smaller number of members, we are able to listen closely, focus on prevention, and provide personalized care that goes beyond rushed visits and fragmented systems. Concierge medicine allows us to be proactive, accessible, and deeply invested in each patient’s long-term health, not just their next appointment.

What Our Clients Say

Joyce Customer

“Tom and I just wanted you to know that today's yoga class with Mary was terrific. We have both done yoga (on and off) for over 30 years and had lots of teachers and she was just wonderful. She was non-judgmental, encouraged us to ask questions and to comment, was an excellent listener and made excellent judgements about our abilities and simultaneously gave us great anatomical info related to a given pose. We haven't only done one in person class since before COVID. It was awful - the teacher was slow and judgmental and had no ability to offer modifications for different levels of ability. Mary was able to both challenge us and keep us safe - a difficult balance.

Just a thought - if you put a place on the website for testimonials - we will be happy to write one about our experiences with Core Concierge so far. Keep up the good work!

thank you! Joyce”

Core Concierge Health has been a wonderful investment for my husband and I. We were totally invested in Kathryn Grinnen and when she decided to go Concierge, we decided to follow her. She is a very knowledgeable, thorough & thoughtful doctor who is insightful into your particular issues. She has given me (us) referrals that have been so helpful & perfect for our needs. She has an incredible knowledge of connections in the other areas of medical needs. The Health Concierge offers free classes of Yoga, Strength & Balace, Chair Yoga & others. It’s such an amazing doctors service that I could never imagine. I feel so privileged & so secure! Check it out!

Dr. Grinnen has been my doctor for four years. I love her expertise and personal care. Because she is such a great doctor, my husband & I followed her to her new Concierge practice . Core Concierge offers FREE classes in Yoga strength & balance, Pilates and tai chi, and even programs on healthy cooking, memory health, etc! I especially love the mat Pilates class with Stacey!

Absolute phenomenal care! I’ve been with Dr. Grinnen (Internal Medicine practitioner) over eight years. When she left the Beebe system and started the new practice with Dr. Gulab, I didn’t hesitate to follow even though a concierge approach was foreign to me. Dr. Grinnen demonstrates the ability to carry out excellent medicine. The concept of the practice is to meet patient's need. I can’t tell you the number of times that I’ve needed same day or next day service, and they make it a priority! And, when you walk in you are greeted by name before you even get to the front desk- imagine?! Personal care, attentiveness, insight with a well rounded scientific approach, NOT RUSHED, willingness to listen to the patient, and a phenomenal supportive & friendly staff create an exemplary medical practice. I am incredibly cared for. As a bonus with my membership, I can access nutritional, cooking classes, seminars, and exercise classes. I am grateful, truly grateful and recommend her care to all ages, for everyone.
