Counseling Center


David Walden, Ph.D.
Welcome to the Counseling Center! I am the Director of the Center and enjoy creating an excellent workplace for myself and my colleagues that serves our students well as they navigate this time in their lives. My therapeutic areas of interest include romantic relationships, childhood sexual abuse, identity issues, LGBTQ and gender identity concerns, dynamics related to marginalization, oppression, and racial identity, and existential issues. My approach to therapy is grounded in a broadly humanistic perspective, and I see dialogue as a way to connect people in their shared humanity. I also value humor as a way to break down barriers to intra and interpersonal connection. In addition to enjoying my time at work, I love spending time with my two beautiful and thoughtful kids, riding my bike to work, rock climbing, and engaging in dialogue with the natural world. I'm working on combining the latter two interests with therapy and provide "Therapy on the Rocks" and the "Wilderness Adventure Quest".

Hidetoshi Hama ("Hama"), Ph.D.
Staff Counselor
Hello! I grew up in Osaka, Japan, and moved to the U.S. in 1999. Prior to receiving my doctoral degree in Counseling/School Psychology from University at Buffalo, I completed my internship at the University of Florida Counseling & Wellness Center. My areas of interest include interpersonal dynamics, international student adjustment concerns, and counseling and advocacy work with students with various dis-abilities. As for my approach to therapy, I strive to develop a strong client-therapist alliance by paying close attention to the client’s narratives and cultural contexts in which s/he lives, as well as by using humor (mindfully, of course!). In my spare time, I enjoy a wide variety of activities with my family and friends, from chatting over cups (yes, plural) of coffee, going to see a comedy show in NYC, to playing tennis and hitting the beach! I am very excited to be a part of our Counseling Center family and meet new people at Hamilton. When you spot me on campus, please feel free to say hello!

Shannon March
Graduate Intern

I'm a graduate intern for the 2016-2017 school year, and am a Clinical Mental Health Counseling master’s candidate at Syracuse University. I obtained a B.A. in Psychology from Le Moyne College. I have been a personal counselor at Syracuse University’s iSchool of Information Technology since 2015, working individually with students to encourage academic and personal growth. I'm excited to discover all that Hamilton College has to offer and to explore the surrounding community, especially the local cafes and farmer’s markets. Outside of the classroom, I enjoy exercise and wellness. I've completed three Boilermaker 15k road races and am most likely to be found walking the outdoor trails whenever the sun is out. I'm also a Central New York native and can give great recommendations about one of the area’s best assets: unique food!

Lily McArn
Therapy Dog

Lily visits the Center on Tuesdays. She is a black lab mix who came to live with College Chaplain Jeff McArn after being placed in a rescue facility. Lily’s interests focus on outdoor recreation, particularly involving squirrel life, but if a rabbit or ground hog are available, they produce a special quiver in her heart. She loves long walks on cross-country trails in the summer and golf course sprints in the winter where deer wander. While pictured above with her book Inside of a Dog, Lily cannot in fact read, but she is a solid couch potato, able to sit through multiple conversations and movie viewings at a stretch. In December, 2015, she drove to Tonowanda, NY for her certification exam to become a therapy dog. She passed her 13-point exam with flying colors and proudly wears her official insignia when she is at work. She has made official therapy visits to Community Memorial Hospital in Hamilton, NY and the Presbyterian Home in New Hartford, NY and is primed and ready to sit with students who desire her company in therapy sessions in the Counseling Center at Hamilton College.
