What our patients are saying

Dr. Scott Herbert, thank you for helping to give me more time. Saving lives is the most heroic work of all. I feel that I’ve been the luckiest person in the world… to have lived to almost 90 is a huge gift! Thank you for your part in that gift, and thanks to all the Nexus team.

Dear Scott,
as you know my dearest friend died on March 20th. My heart is broken, and these have been difficult days. One of the rays of light in the past few months has been you. Your home visit helped my friend cross over onto the path of palliative care and prepare for death with dignity. You have always amazed me with your insights and compassion for human life. Your presence moved me to tears. My friend deserved the best and you were the best person to help her. I miss her so much. Knowing you were with her brings comfort to my heart. Thank you for being you.

Dr. Snyder and wonderful staff, all of the best to you at this great looking and comfortable facility! Quoted from Oxford Dictionary, “Nexus, the central and most important point or place”. My family and I agree! Our thanks to you for all you have done over the years. Salud!

I saw Dr. Bulthuis for an ankle sprain/fracture. He explained the healing process of my ankle. I had been given conflicting information from other providers and he spent the time to explain why he gave me the plan he gave. He answered all my questions without being rushed. The staff was also efficient, professional, and attentive. I highly recommend Dr. Bulthuis and the staff. I left the office encouraged and with a clear plan.
