trusting relationship

I appreciate the access to and responsiveness of Marion, along with her coordination of care with other providers.  I also very much value the building of a trusting relationship with my kids.  I think Marion is great!

she has always given me support

Just knowing I have Dr. Owen in my court is reassuring.  She has always given me the support I need.  WE both know that optimization of all aspects of the human experience–physical, spiritual and mental, are key to living the good life.

Fortunately, since lifestyle habits are utmost in my mind as the most importand means to maintain optimal health, as they are with Dr. O, I have not had much need to “see” her beyond my annual physical.  I do know that when I have needed more than that consultation, I have been in good hands, whether it be from a natural supplement or, if needed, a pharmaceutical standpoint.

unique in the market

I have found your practice to be unique in this market.  Dr. Owen’s approach to assessing and administering medical care is unlike the traditional “bandaid” approach in most practices.  Having the ability to get medical support as needed is also extremely valuable.

I feel cared for . . .

I feel cared for and that they care about me!  That is a rare but important quality for a doctor/doctor’s office.

She always goes the ‘extra mile’

I am grateful for the wonderful care my family receives from Dr. Owen.  She always goes the ‘extra mile’ – she makes all of us feel as if we are her only patient.  The time and care and compassion she extends to us is phenomenal.

– Connie Z

Love that my whole family is connected. . .

Love that my whole family is connected and can get your help at a moment’s notice.  Also like understanding of our personal health and coordination of care. Love you all.

Dr. Owen is proactive with her patients, listens carefully to them to assist us in making the best decisions to promote health and using medical interventions only when preventive measure have not proved effective.

A trusted and quick medical opinion

At the pace of todays lifestyle for most of us, it is important to have quick access to a medical opinion that you trust.  In Dr. Owen I feel secure in requesting medical opinions from someone who knows my medical histor, truely cares about me as a patient, and will respond quickly to the small concerns before they become larger concerns.  Most of us would put off seeking care for small concerns because of the time it takes to get this opinion.   The concierge medical model allows me to feel comfortable making a phone call or sending a digital message to address concerns without that large investment of time.  Then if deemed necessary further testing can follow.  I highly recommend While Family Medicine as a practice placing as much emphasis on preventative care as on treating symptoms.  This should be the future direction of medical care.

Personalized, Unhurried, Compassionate Care

I’m very grateful to have found a doctor who has chosen to practice medicine in a way that promotes optimal health. An office visit with Dr. Owen is at least 30 minutes, and this amount of time makes it possible for her to do the kind of detective work necessary to solve complex health problems. Her keen intelligence, curiosity, and eagerness to research and innovate on behalf of her patients achieve results. Her focus on the whole person, as well as her genuine interest and compassion, add immeasurably to her effectiveness as a physician. The origin of the word “doctor” comes from the Latin word “to teach.” Dr. Owen excels at this as well, and the more I learn, the better able I am to manage my health.

There are many other benefits to having Dr. Owen as my physician. It seems to me that a visit to a doctor should make you feel better, not worse. I find that other medical facilities cause significant distress—the robotic routines, the sterile waiting rooms, the relentless adherence to rules and regulations – all these leave me feeling stressed and helpless. And of course, there is always the anxiety of having to condense complicated problems into the five minutes available for the consult.

In contrast, going to Dr. Owen’s office makes me feel better every time. Her genuine interest and compassion, and her love for this work, permeate everything. The staff is kind, responsive, interested, and helpful. The office décor is comforting and beautiful. All these things promote healing.

I have found help for everything from complex, chronic conditions to more simple needs like a second-degree burn. Susan, the nurse practitioner, took such good care of me when I had the latter problem. Her superior medical skills are matched by her gentleness and kindness. Like Dr. Owen, she always takes the time to answer my questions and address my concerns completely.

Real healing takes place in the context of a relationship. It’s rare for a doctor to practice in such a way that there is time to know and understand the patient’s personal and family history. This is the way medicine should be practiced – personalized, unhurried, compassionate.

Takes ME Into Account, Not Just My Symptoms

Let me start out by saying I don’t go to the doctor much; in fact, avoid them when I can. That’s because most doctors are all about prescribing medicine, doing surgery, or some other intervention. I believe the body has its own ability to heal and that sometimes it needs a pointer in the right direction or maybe a nudge, and certainly a closer look at how it’s functioning in order to troubleshoot an issue or imbalance. That’s what I know I will get at Whole Family Medicine.

In the years I’ve been seeing Dr. Owen, Susan Castle, and the crew at Whole Family, I’ve had a handful of issues where stress pushed my body’s systems over the edge. This required a holistic approach, not just a pill. It is this whole-person management I respect in a doctor and a clinic – a system that takes me into account, not just my symptoms. It’s what’s missing in health care and many other areas of our culture.

My kids see Dr. Owen for her knowledge, holistic approach, and her accessibility. That’s probably the best thing about Whole Family. They are kind of like our family, even though we don’t see them often. All the staff has been absolutely there when we needed them, especially last-minute school and medical paperwork. My oldest daughter, now 21, has her own personal relationship with Dr. Owen, now an honorary member of the village of Mae. As a mom, that makes me so happy.

lifelong proactive medical care

Dr. Owen is that rare doctor who truly cares about her patients as individuals. With patience, she has promptly answered numerous questions both by phone, by email, and in person. Because of her knowledge, she has been able to prescribe medicines and supplements appropriate for my specific issues taking into account my body’s specific level of tolerance. Susan Castle, the Nurse Practitioner within the practice, is equally compassionate, competent, and thorough.

From the time I walk in the door in the waiting room (stocked with current, enjoyable magazines to read), until the time I leave, I feel treated with dignity and respect. I wholeheartedly recommend this practice to anyone wanting lifelong proactive medical “care.” Thank you Whole Family Medicine for helping me!

– Terry W.

Dr. Owen Is a True Gift

Thank you so much for all you have done to help me. I could tell from my first visit with you that you truly wanted to help me, really heard my concerns, and went straight for the root of the problem rather than prescriptions to mask the symptoms … it is such a relief to be back to my true self again. I feel like I have my life back! I cannot thank you and Dr. C enough. You are a true gift.

My Care is Handled Thoughtfully

I really enjoy the access to the Patient Portal. I love Susan and the front desk as well. All around I feel like my care is handled thoughtfully and compassionately, and feel extremely lucky to be associated with Dr. Owen and her practice.

immediately felt at ease

I am a fairly new patient and immediately felt at ease with Dr. Owen, Susan, and all staff members. Dr. Owen (and Susan) seemed to have a clear understanding of my health history and made recommendations based on it.
