Realizing the benefits of massage therapy in a person's healing process, I organized and coordinated the massage therapy efforts for rescue workers at the Murrah Building Bombing Operations Center. Services were provided around the clock during the 2 week rescue and recovery efforts. Massage services were again coordinated with the Department of Justice for victims and survivors at Project Safe Haven during the trials of the perpetrators and later for volunteers and victims of the May 3, 1999 tornado in Moore, Oklahoma.

After long term physical therapy, cortisone injections and massage, that only worked temporarily, I finally found relief for low back pain! I was skeptical, but now am a believer in acupuncture! Thank you Dr. Gumman!

I saw Dr. Gumman throughout my pregnancy and it was amazing!! I napped during most of my sessions and always left feeling so relaxed. I had a wonderful birth and I’m so glad I incorporated acupuncture into my labor preparation!

[Dr. Gumman] has changed my life and taken away the pain from my frozen shoulder. He helped me with my range of motion too. I’d recommend him any day.

I currently live in Ada, Oklahoma. I had been searching for a colon hydrotherapist for quite some time, but I never found anything in my area. Finding Karen at Harmony Healing has been life-changing for me! Karen has made my experience with colon hydrotherapy very relaxing, and I always feel very comfortable around her. My sessions with Karen have greatly decreased my abdominal bloating and cramping, and my body feels more refreshed than ever before. I look forward to every appointment with Karen, and every minute of my long drive is worth it!
— Kelsie
This is the absolute best colonic I have ever had. I have had colon hydrotherapy sessions at numerous locations from coast to coast in the United States. Karen is a RN with many years of traditional nursing experience combined with her colon therapy training and the result is impressive. Oklahoma City is fortunate to have Karen and the beautiful spa-like hydrotherapy room with a private attached bathroom and shower at Harmony Healing Center. I highly recommend her Colonics.
