I genuinely appreciate the warmth, empathy & encouragement expressed by Dr Cox & his staff. Enduring illnesses can be very scary, but thankfully amazing doctors such as Dr Cox exist who reminds us that we aren't in the "battle" alone. To him we aren't simply a job. Our health & wellbeing genuinely matter to him & he's appreciated more than mere words could ever express.🥹
