Max the Carolina Dingo Dog teaches kids about his body and, therefore, teaches them about their own! Read to your kids the precious tale of MY BODY IS MY BUDDY to learn about the fuel (food) the body needs to run as well as the fuel (love) that the heart needs to thrive.



Associates at Park Avenue is a practice of absolute professionalism balanced with warmth, kindness, honesty, and respect for our individuality as well as our collective humanity. Walking into the APA's lovely building on historic Park Avenue one might hear silence, soft music, sounds of water flowing, or laughter, tears and joy of true compassion, cammaraderie, humility, and fun. With about a century of experience amongst us, though we each have our areas of expertise we complement one another's work and hold ourselves accountable for the same goals we promote for our clients: to do our own work, to take responsibility and to grow with what we have; to strive for more while embracing the now. Whether we are working on our relationships, ourselves, our work environment, or our families, we believe in doing so with clear principals and goals.
